ExNotes Product Review: Continental Twinduro TKC-80 Motorcycle Tire

By Joe Gresh

I’m probably the worst person to review a motorcycle tire. Round and black are my two major criteria for tire performance. If the tire meets those benchmarks it’s okay by me. I’m not sensitive enough and I don’t ride fast enough to push any tire to its limits and I couldn’t tell you if brand A is better than brand B on the street if my life depended on it. Which is why the Continental TKC-80 is such a revelation on the Husqvarna SMR510.

It’s not easy to find a decent 17-inch front tire for the dirt. The front tires I had been running on the SMR510 were those hokey, 70%-street/30%-dirt or 80%-street/20%-dirt tires that are all really just street tires with a few extra adventure-grooves cut into the tread pattern. The street-based tires worked well on the street (see my criteria above) but were horrible on the dirt. The Husky’s front end would push through corners completely devoid of grip or feedback.  I had to sort of square off turns: enter straight, come to a near stop, change direction and exit under throttle.

I don’t need the Husky for street duty now that the Kawasaki ZRX1100 is running.  Long time ExhaustNotes readers may recall my failed efforts to convert the Husky’s tiny, 17-inch front wheel to a more dirt appropriate 21-inch size. That was a real debacle that cost me hundreds of dollars resulting in the 17-inch wheel going back on the front of the motorcycle.

Having wasted so much blood and treasure on the front wheel conversion and coming up empty I decided to try the tire everyone told me to get in the first place: Continental’s mostly off-road TKC-80. Originally made for giant, 600-pound ADV bikes I figured the TKC-80 should hold up well on the lightweight Husqvarna.

The improvement is so dramatic even I can tell something good happened between the Husqvarna’s handle grips and the ground. The Husky actually steers in the dirt now. It goes in the general direction you point the handlebars. I can take a corner in the dirt leaning the bike over like I’m on pavement and the front end feels planted. It’s like I have a whole ‘nother end of the motorcycle to work where there was nothing but push before. Soft sand is no problem, graded roads with a thin layer of dust and pebbles feel almost grippy. I haven’t been in the mud yet but the 80 has to be better than the slick tires I was running.

Needless to say I’m sold on the TKC-80, so naturally there is some confusion (on my part) about the future availability of the 80 series. Apparently, there was a recall on a bunch of Continental tires including the 80 series due to tread cracking. The best I can sort out from the Internet is that TKC tires built between January 2019 and April 2022 are affected by the recall. I’m not even going to look at the date code on my tire because I’m not taking it off. One of my moto-insider buddies says Continental is discontinuing the TKC-80 series. I haven’t found confirmation on that but as of today you can still buy them. I have noticed that TKC-80s online have gone up quite a bit since I bought mine at $120 a copy.

If you own one of the Super Motard type bikes with 17-inch rims and want to play around in the dirt without having to convert your front wheel to 21-inch, the TKC-80 is your tire. There is no cheaper or easier way to improve the front end of your motorcycle. I can’t speak to the TKC- 80’s longevity as I only have around 500 miles on mine and it shows little wear. If the thing lasts 2000-3000 miles it’s well worth it for the offroad performance. Hopefully I’ll be able to buy another one in the future because it’s about the only option for a 17-inch knobby that will fit the Husky’s wide rims.

The Motorado Vintage Motorcycle Meet, Santa Fe, New Mexico

By Joe Gresh

We were flying low and slow, like vatos do, heading north from Mountainair, New Mexico. The Mud Chuckers, one on a Buell 1000, one on a Kawasaki Vulcan 750 and me on the 1974 Yamaha RD350. It had been a few years since the last Motorado event and we decided to ride up as a group. Covid and inertia combined to equal a 4-year gap since the last Motorado event. Last year in 2022 we held an unofficial Motorado rump-meet at the traditional location. About 15 old bikes showed up and no one drank beer because the pub was closed. There was a swap meet going on and we drew some interested lookie-loos. It was better than nothing for sure and I was prepared to go do it again this year but the real Motorado got on the pipe.

Saturday’s weather was warm and sunny and none of us felt in the mood to go very fast so we burbled along at 50 miles per hour enjoying the beautiful, two-lane New Mexico scenery. Traffic was typically light.  Three cars passed us. At this stately pace the old two-cycle, twin cylinder Yamaha RD350 progressed 58 miles for each gallon of gas. That number would be a lot more impressive except the ancient, 1950’s era Sportster motor powering Mike’s Buell did 68 miles per gallon. Long stoke, four stroke, no poke, no joke.

A Vulcan 750, an RD350, and a Buell.

The unofficial, official motel for Motorado 2023 was the Sunset Motel in Moriarity, New Mexico. The Sunset is laid back and low slung just like us. You don’t get breakfast at the Sunset but you do get a monster homemade muffin, which is almost the same thing. After getting settled in our rooms we rode off to get dinner at Shorty’s BBQ joint.

Shorty’s has the best BBQ brisket in Moriarity but the place is always in kind of an identity crisis. The first time I ate at Shorty’s the walls were covered with Jesus stuff, bible quotes and crosses.  A few years later I stopped by and the entire restaurant was a shrine to Donald Trump. The Mud Chucker’s are about as far from liberal as you can get, but are also not too fond of The Donald so I feared the worse going in, but the décor had changed again. Now the place was Jesus-lite® without a single reference to our 45th President and a marked reduction in Christian symbolism. You get to experience Shorty’s political and spiritual evolution through the walls of his establishment and eat a great brisket sandwich to boot.

Late September in New Mexico is prime motorcycle riding season. The mornings are cool, gradually warming to hot afternoons. Elevation changes and drifting clouds create a seesawing temperature landscape. The Mud Chuckers were moving slowly on Sunday morning and I’m of that certain age where I no longer care whether I arrive anywhere at any particular time, so we managed to pull out of the motel around 11 a.m. From the Sunset, it’s a straightish shot up Highway 41, through Galisteo to Highway 285 and then north a few miles to the Motorado.

There was a good crowd at the 2023 Motorado. It looked to me as though they had not lost any attendance despite the 4-year layoff. All brands of old bikes were represented and several shops had booths selling whatever it is they sold. I hit the Motorado T-shirt booth first but they weren’t set up to take credit cards and I had a limited amount of cash on hand.  Once again it was no T-shirt for me. This whole T-shirt thing is out of control.

One of my dream bikes, a Kawasaki Avenger 350. These disc valve two strokes were pretty fast back then and still fast today.
High pipes on a Norton P-11.  This is pre-isolastic mounting so you get to feel every vibration the parallel twin puts out.
Every Motorado I see a bike I never knew existed. Here’s a Taurus diesel that looks a lot like Royal Enfield running gear strapped to a diesel engine.
This over restored but still beautiful Ariel Square Four was a stunner. I hung around to hear it run but got tired of waiting.
The oldest bike at the event, a 1906 Fairy opposed twin. Not sure of the horsepower but they made 2-1/2 to 8 horsepower models. I bet the 8 was a real screamer.
This bike is the great grand-daddy to the RD350. Two generations behind the RD it’s still a sweet looking bike.

After a few passes we had seen pretty much all the bikes in the show and the swap meet. The Chuckers and I took the long way home on the Turquoise Trail through Madrid, New Mexico and got back to the Sunset motel at Sunset. Moriarity rolls up the sidewalks on Sunday night and all the regular places were closed so we retreated to a 24-7 truck stop that had the worse spaghetti ever made, and then we called it a night. It’s tough eating night-spaghetti.

The morning ride from Moriarity was brisk bordering on cold and our rag-tag group made the 200-mile rode low and at our now standard slowpoke speed. I’m very happy the Motorado is back in business and barring another world-stopping pandemic I hope they stage many more years of vintage shows. As long they hold the meet I’ll be riding an old bike up to Santa Fe to check out the hardware. I’ll see you there next year. Swing by the Sunset Motel and we can ride the last 50 miles together.

ExNotes Review: Oxilam LED H4 Headlight Bulb

By Joe Gresh

The Carrizozo Mudchuckers and I took a spin over to Jerome, Arizona last week. The trip was around 1200 miles all in and we ran late getting home, which meant I had to ride 100 miles in the dark. Normally I avoid night riding because most of my motorcycles have terrible headlights and my night vision was dim before I had both my cataracts replaced with new lenses. Plus, at night you can’t see anything except the road ahead.  It’s pretty boring.

For the Jerome trip I was riding the Kawasaki ZRX1100; that bike has the best headlight out of every motorcycle I own. To my surprise the night ride was not as bad as I thought. I could see fairly well and made it home without running into an elk. Which got me thinking about the shorter days of fall and the fact that I sort of enjoyed that 100 miles of darkness. Could I improve on the acceptable Kawasaki headlight?

Enter the Oxilam LED H4 bulbs I purchased on sale from Amazon at $39, shipping included. They are a tad pricey but you do get two of them. Oxilam’s ad copy makes wild claims about 500% brighter and 10,000-hour life span. I can’t speak to the lifespan but the bulb sure doesn’t look 500% brighter.

The Oxilam came securely packaged in a nifty carton with a fitted foam insert. Included in the box was a pair of gloves so that you don’t get your greasy fingers all over your nice, new bulbs. It’s a beautiful product presentation and gives a real sense of value to the whole operation.

Installation was easy as pie: remove your old bulb and insert the new one. The dimensions of the Oxilam are nearly the same as a standard H4 bulb so you don’t have a big heat sink or cooling fan jutting out the back of your headlight housing.

The Oxilam has a tiny cooling fan built into the front of the bulb. That worries me a bit but I’m rolling the dice here. Some reviews of the Oxilams claim the fan to be noisy. I don’t see how such a tiny fan can make much noise and I can’t hear it.

I couldn’t find a watt rating anywhere except an ad copy line stating the bulb draws a similar amount of current as a standard H4 so computers will not act up thinking a bulb is out. Lumens are a claimed 18,000 so I guess that’s good.

Maybe not 500% brighter but the Oxilam LED bulb is noticeably brighter than the original 24 year-old halogen bulb it replaced. Low beam is a lot better with a sharp cutoff so you don’t blind oncoming cars. Low beam is wide and bright.  The 6500 kelvin white light makes colors pop a bit more at night. Grass looks greener and the road edge is more obvious. The light produced is evenly distributed without any hot spots. It’s really wonderful. The Oxilam is worth it to me for the improved low beam performance.

High beam was also improved but not as dramatically as low beam. High beam seemed to reach a little farther out than stock and the white color was nice. One drawback to the increased lighting power was that reflective road signs were very bright on high beam, bright enough to cause me to drop back to low beam until the sign was passed. Installed in the ZRX lens there is an overly bright spot 10 feet ahead of the front wheel, I feel those lumens could be put to better use 100 feet down the road. I suspect the Oxilam will project differently depending on which headlight housing it is installed.

The Oxilam bulbs are worth the $39 to me. With my creaky vision I need every advantage I can get at night. It was actually not bad riding in the dark with the Oxilam and the new bulb will extend my riding time by a few hours each day. That’s got to be worth something, right?

Becoming Vulcan Part 1: The Vevor 130

By Joe Gresh

I first started welding when I was around 12 years old. My Pop gave me a few tips and handed me an oxy-acetylene torch. He showed me how to set the mixture with a haze of blue slightly beyond the core blue flame. He told me the filler rod is used to cool the puddle, not to melt into the gap. And he told me to keep moving when laying down a bead or you’ll burn through. With these simple lessons I never learned another thing about welding. When I worked at SWATH Ocean building aluminum boats I did a bit of MIG and TIG welding as needed for my electrical work. I could make a passible bead but I never knew why or how it worked.

At SWATH the real welders would set up the machines so that even an idiot like me could weld without an understanding of welding. We used giant, high-frequency start, Syncrowave machines that crackled all the telephone lines in a 500-foot radius. Orange colored MIG (metal inert gas) spool guns tied to large power supplies were strategically placed throughout the vessel making it super easy to attach brackets or braces as needed. During working hours the air inside the boats sparkled with aluminum dust and smelled astringent from the inert argon gas. We used to joke that cigarette smokers were the healthiest workers at SWATH because they breathed through a filter.

Over the years I’ve lost the muscle memory for welding and my beads are a jumbled mess. My hands are shaky, my near vision is compromised and I can no longer make presentable welds using any process. I’ve decided to educate myself on welding in general and welding processes that didn’t exist 40 years ago. Thanks to the global economy, welding machines (like most electronic products) have dropped dramatically in price. The advent of the small inverter welder for home use has been a giant leap forward.

I purchased this Vevor 130 multi-process machine from Amazon for only $120, shipping included. The Vevor runs off a standard 115-volt wall receptacle. In the past (where I spend most of my time) a machine with this capability would be ten times the price. The “multi” in multi-process refers to the Vevor’s ability to weld with flux core spooled wire, stick weld or TIG weld. The unit came with all the cables and guns needed for each type of welding process. It did not come with a cart, argon bottle or flow meter. The Vevor is meant for welding steel but there are some stick (also called MMA for Manual Metal Arc) rods available that will weld stainless. You might be able to weld stainless with the Vevor TIG (tungsten inert gas) torch but I haven’t tried it yet.

In stick mode the Vevor is a pretty standard welder like the ones that have been around forever. The old buzz boxes put out alternating current unless you bought an expensive AC/DC box. I had a Miller 225 AC/DC unit that suffered from a lightweight transformer and it was a bitch to strike an arc with the thing. As soon as the stick drew current the voltage would drop and weld the stick to your work. My Pop’s old Lincoln AC welder weighed a ton and I could strike an arc easily with that machine. Hysteresis matters when it comes to the old-style arc welders.

The Vevor puts out DC current all the time and being so light it’s hard to get the thing going in MMA/stick but if you scratch around long enough you can get an arc struck. Once burning, the Vevor seems to work like any other arc welder. Rated at a doubtful 130 amps, my Vevor tripped the 15-amp breaker in the shed at around 90 (indicated) amps. You’ll need at least a 20-amp rated receptacle to access all 130 amps, maybe even a 30-amp socket. Like all welding, stick welding is an acquired skill. The rod is continually getting shorter so you have to move your torch hand closer and closer to the work to maintain the correct distance. When your glove starts smoking it’s time to stop and get another rod. You’ll need to practice quite a bit before you make decent looking beads with stick. There is also a bit of splatter with stick.

Flux welding is a lot like stick, except instead of flux-covered rods you use a spool of steel wire with the flux inside. Flux core seems the easiest process to me. Setting up the machine is important but once you’ve got the wire speed and amperage right it’s pull the trigger and go. And go you can because you don’t need to stop and clamp a new rod in the holder to replace the ones you’ve consumed. The welder keeps feeding wire to the gun at a pre-set pace and your hand maintains the same distance the whole way through. Eventually the spool will run out but that’s after many feet of weld beads. Flux core also starts easy, for me anyway.

Flux core also splatters a bit like stick, maybe less. It’s no big deal (you can knock off the slag and balls of spooge afterwards). I am a total rookie at flux welding so I’ll need a lot more trial and error to get things right. Most YouTubers will tell you to buy a better roll of flux wire as the roll supplied with these cheap welders is not so great. After I run out I’ll buy a name brand roll of flux core to see if it makes a difference.

TIG (tungsten inert gas) welding is the coolest process of all. TIG usually uses an argon gas bottle to supply a flow of shielding gas to your weld. The actual process of welding is similar to oxy-acetylene welding except the torch is electric. With argon you don’t need flux but your material needs to be fairly clean. Unlike stick welding, you can’t just plow through rust and contaminated metal. TIG uses a tungsten rod as an electrode, but the rod is super tough and does not get consumed very fast.

My biggest problem with the Vevor in TIG mode (besides the fact that I am a terrible welder) is I forget to turn on the argon gas at the torch handle resulting in a burned mess and contaminated tungsten. More expensive machines do this automatically. The Vevor uses TIG lift, a method to strike an arc that seems to work fairly well most of the time. The expensive machines I mentioned above have a high-frequency start that keeps you from sticking the tungsten into the work and contaminating the rod. The TIG lift system works pretty well, I have no problem getting a TIG arc started with the Vevor.

With TIG you’ll usually need to add in filler rod just like torch welding. This is another hang up for me as my control of the filler rod is shaky. I often stick the rod onto the tungsten then I have to stop and clean the tungsten before going on. Dirty tungsten produces a crazy arc that wanders around or shoots out the side. The melted weld puddle is all over the place. It’s like playing whack-a-mole when this happens.

As I’ve said before, I’m a terrible welder so don’t hold these sample beads against the Vevor 130. A welder who knows what he’s doing will have no problem making decent beads with this machine. I am practicing on thin sheet metal mostly because I have a lot of it I cut out of an old file cabinet, and welding thin metal develops a better feel for heat control. I’m constantly burning through thin stuff. In these sheet metal samples the TIG produced the best-looking welds, although all of them are horrible.

As you can see from the backside, penetration on the thin steel was not an issue. Everything I did was too hot and was on the verge of burning through.

The above samples are on 1/8-inch thick steel. It’s an assortment of stick, TIG and flux core. If you look closely, you’ll see fleeting moments when everything was going well, followed by disaster. I give the $120 Vevor 130 high marks for economy and it really does weld all three processes. I haven’t yet welded long enough to overheat the machine, a common problem with cheap welders. If you want to weld 8-hours a day, you’ll need to spend a few thousand dollars.

I’ve been watching tons of how-to-weld videos and I plan on taking a welding class at NMSU next semester (Go Aggies!), my goal being to sort this mess out and produce some decent welding before I die. Note: All the samples in this story are just running beads. It’s harder to actually stick two pieces of metal together. Hang around ExhaustNotes.us long enough and you’ll see if I ever do become Vulcan.

ExNotes Product Review: Waymo Self-Driving Cars

By Joe Gresh

There is a megacity out in the Arizona desert. It runs for miles and miles, ever expanding into the scrublands. Phoenix, Chandler, Tempe, Scottsdale and other towns have merged into one, giant, golf course subdivision splattered with Wal-Marts, drug stores and tilt-up warehouse mattress vendors. It’s hot, dry and thirsty. I don’t understand why so many people willingly bake in the sun. Waymo, the self-driving taxicab company has found a way to eliminate a few of those people.

ExNotes tested the Waymo’s plying the streets of downtown Tempe. Laid out in a grid pattern with tall buildings blocking radio signals Tempe would be a tough test for Waymo. How the system works is you download an app and enter your information. Next you order a car telling Waymo where you are and where you want to go. How long you wait for a car depends on traffic or rider loads. CT and I took Waymo rides three times and the usual wait was 5 or 10 minutes. The Waymo cars we rode in at Tempe are made by Jaguar and look like any generic, white SUV-ish car, except the Waymo’s bristle with cameras and sensors on all four corners and the roof.

Let me cut to the chase and tell you the actual driverless-car part worked great. You can sit in the front seat or rear seat, once inside with your seatbelt on you push the start field on the dash display. The Waymo will watch for traffic and pull out onto the street just like a person is driving. The car still has a steering wheel that spins around as the car makes corners. The Waymo doesn’t pussyfoot around, either. It accelerates right up to speed and takes curves with a bit of hustle. It stopped at stop signs, circled roundabouts and waited patiently at traffic lights.

I felt totally comfortable sitting in the passenger seat letting the computer drive. I suspect that’s because I’ve been installing autopilots in boats for 50 years. From the first Metal Marine Pilot to the latest digital units tied into GPS and radars. I’m used to sitting at the helm with the boat steering on its own. Of course there are a lot less things to run into on the water compared to downtown city streets, but I saw the Waymo as just a fancier version of electronic stuff I’ve dealt with for years.

As there is no driver, there is no need to tip. The short Waymo rides we took cost around $4 each and the money is charged through the app. You get in, arrive at your destination and get out. Oddly enough, the technology of the self-driving car wasn’t where Waymo fell down on the job.

Our problems came during the pick up process. Waymo’s app will tell you to walk 700 feet this way or head 350 feet south on Fifth Street feet while you’re waiting for the car. You can watch the car’s progress on the app and judge arrival time. After following the apps instructions we found it best to ignore the app and stay in one spot and wait until we could see the Waymo, and then walk towards it.  Pick up was usually fairly close but one time the car waited for us about a block and a half away.

We were walking all over trying to find the thing. Waymo’s app has a toot horn feature and we used this to echolocate the car. Upon our arrival the car decided it had waited long enough and drove off. We were 15 feet away. It’s kind of dumb because Waymo knows your location via the phone app. It knows how far away you are and can see you moving towards the car. Also, Waymo needs a “Pick me up where you dropped me off” feature to cut down on walking time. As the software is configured now Waymo might drop you at the front door of your destination but when you call for a pickup the car might be down by the river.

Long time ExNotes readers will know I’m not the sort of guy known for embracing the future. But being a motorcyclist I can see the advantages of ever-vigilant computers replacing the brain-dead car drivers that kill us so often. I’d rather ride in a megacity full of Waymos than the usual collection of phone texters, blind drunks and road ragers.

It’s still early times in the self-driving car business and the road driving part is already amazingly good. I could tell no difference between the Waymo and a human driver. The weather was perfect in Tempe so I can’t speak to how the car would perform in a snowstorm or on icy roads. Maybe it defaults to park? I can see personal self-driving cars becoming popular if we can figure out all the legal ramifications and who gets the blame in an accident. But it’s not like we don’t have accidents now. I say bring on the future.




ExNotes Product Review: Harbor Freight Double Cut Saw

By Joe Gresh

Harbor Freight’s economy brand, Chicago Electric, has been much improved over the years. Back in the 1990s you were lucky to get a few months use out of a CE tool before it burned up. Of course, what did you expect from a 10-inch circular saw that cost 15 dollars? They were sort of one-use tools, bought for a particular job then tossed in the trash after the job was done. This early crappiness has tainted the Chicago Electric brand and there might still be a few dud CE products out there.

I’ve had pretty good luck with more recent Chicago Electric stuff. Their paddle-switch 4-inch grinder has lasted 10 years for me and is still going strong. I have a Chicago Electric sawsall that is pretty old and it has held up well. You no longer get smoke pouring out of a Chicago Electric tool the first time you plug it in.

This Chicago Electric Double Cut saw is marked down on clearance at 44 dollars. In Harbor Freight land a clearance item usually means the tool is being discontinued and when they are out they are out. I had to get my local HF technician go into the back of the store and rummage around to find one. You may have to visit several stores to find one. Clearance tools are usually superseded by a similar tool with a possible upgrade in quality or just bold new graphics so if you can’t find a Double Cut saw just wait a bit and another one with a different part number will appear. Although, it won’t be $44.

I’m impressed with the improved quality of the CE Double Cut saw. The castings, both metal and plastic look well made and finished nicely. This saw has a bit of heft so at least there is some copper and steel in the thing. The saw comes mostly assembled, you only need to put the grab handle on and feed a lube stick into the nifty feed hole provided. Like most CE power tools the cord is stiff and plasticky I guess it’s better than the SO type of cord with the easily damaged jacket. The saw comes with a nice little wrench for changing the two (included, carbide-tipped) blades.

Ergonomically, The saw has some issues for me. The power switch is an odd, push down and forward, deal that takes some getting used to. You have to hold the switch on, this puts your hand close to the front of the saw and your other hand is holding the grip nearby. I would move the switch aft on the tool to give better hand separation and thus more steering control. By necessity, the saw blades are almost completely shielded which makes seeing your cut line impossible. There is a V- notch in the front of the blade housing that gives an Idea of where the cut will be. If you want a precision cut you’ll need to rig up a fence. By the way, don’t even think of removing the shields as the Double Cut puts out metal particles when it plows through steel. Wear safety goggles!

What makes the Double Cut somewhat unique is the two, counter-rotating blades. This arraignment cancels out any kickback or climbing out of the cut. Cutting round stock is a breeze, as the material doesn’t try to spin when the blade makes contact. The saw feels wonderfully neutral in action and not the least bit scary cutting steel. The saw is useable on most any material: steel, aluminum, and wood. There is a blade lube feature for use on stickier metals like aluminum or sappy woods. I bought the saw for metal.

I’ve used the saw on 1/8” mild steel and it cut like a hot knife through I Can’t Believe It’s Not Butter. Again, there’s a fine mist of metal particles generated while cutting so wear those goggles. The finished cut is clean with no sharp flashing like with a 4-inch abrasive cut off wheel. On sheet metal roofing the saw cuts as fast as you can push leaving a clean, square edge to slice your finger on when you hoist the panel onto the roof. If you do metal roofs you need this saw.

I probably should take the saw apart and grease the internals but the thing might fly apart on disassembly so I’ll use it as is for the foreseeable future. The depth of cut is only 1-1/4’ but really, if you tried cutting steel that thick you’d probably burn up the saw. Blade depth adjustment is in your hands as there is no hinged foot to set the blade. I don’t know how long the blades will last cutting steel and if the saw is truly discontinued you might want to stock up on replacement blades available at your local Harbor Freight store.

The verdict is in and I pronounce the Double Cut a fine deal at only 44 dollars. If you work with thin-ish metals, say 1/8” to sheet metal this could be your saw. For complex cuts I still use the 4” grinder with an abrasive, metal cutting blade because the line of sight is better, you can see exactly where the blade is. Harbor Freight isn’t the only company that makes this type of saw. Other brands are available, here’s one online at Amazon and the saw looks about the same.

ExNotes Book Review: Mi Papi Tiene Una Moto

By Joe Gresh

If you’re looking for the rare children’s book that features a motorcycle as the prime mover, Mi Papi Tiene Una Moto is the book for you. Mi Papi Tiene Una Moto is made of sturdy paper and the covers are thick cardboard so the thing should hold up well to repeated reading by destructive little hands.

Warning:  Spoilers ahead!

Mi Papi Tiene Una Moto is written by Isabel Quintero in Spanish so your target child will learn a few Spanish words along the way, unless they already speak Spanish. Who knows, maybe reading Mi Papi will generate a life-long interest of languages in your spawn. With my very basic Spanish skills I was able to figure out most of the text and any words I didn’t know I looked up on the Internet. Even if you don’t understand a single syllable of Spanish the beautiful illustrations by Zeke Pena tell the story in an exciting and colorful way.

The book begins with a young girl’s father coming home from his job as a carpenter and the two go for an afternoon motorcycle ride. During the ride the have various little adventures. They visit folks picking lemons; they are chased by dogs; Papi stops and chats with some fellow workers.  There’s even a fantasy sequence involving old style racecars on a circuit through town (maybe it wasn’t fantasy, my Spanish comprehension is not so good).

These micro adventures really remind me of why I like to ride a motorcycle. Simple acts seem more vital: making a turn, waving to a bored kid staring out a car window or just feeling the breeze. Mi Papi Tiene Una Moto’s motorcycle trip ends like all of them should: at the snow cone vendor for a sweet treat.

If you’re an ATGATT Nazi you probably shouldn’t get Mi Papi Tiene Una Moto.  They wear helmets but the hot weather finds them in shorts and light clothing. Spare me the clichés: “Dress for the slide not the ride.” “Gear is cheaper than skin grafts.” You make your choices and the riders in Mi Papi Tiene Una Moto made theirs.

I’ve only shown a few of Zeke Pena’s fabulous artworks in the book and just looking at the stuff made me want to go for a ride. It’s that exciting. Amazon has the book in hard cover for $17 and that’s the only way you should buy the thing. You need to feel the solid way the cover opens and the smooth, cool pages. Kids get enough content with their phones, give them a real world, tactile experience that will create a lifetime memory. I think there is an English version but reading Mi Papi Tiene Una Moto in the original Spanish makes it seem more like a secret world that only your kid can access. At least I felt special decoding the thing page by page.

Mi Papi Tiene Una Moto reminds us that we don’t need to do heroic, epic rides every time we swing a leg over our motorcycles. We don’t need the latest electronic buffoonery to enjoy the simple act of riding and interacting with our environs. I highly recommend Mi Papi Tiene Una Moto for both kids and adults who are not yet dead inside.

Evans Brasfield

By Joe Gresh

I have conflicting emotions writing about Evans Brasfield. He was killed on a motorcycle recently and he was my editor for a brief time at the website Motorcycle.com. The thing that bothers me as a writer is: Am I doing this out of respect or will people think I’m somehow using Evans’ death to fill space in this web site? If you write a lot of stories like we do here on ExhaustNotes.us there is an endless search for topics. I hope I’m not doing that but Evans would totally understand my quandary and I hope approve. Lots of people knew Brasfield much better than I did. I should probably shut up and let them tell his story. Still, I want to write about this man I never met in person and only emailed with or spoke on the phone.

After I was booted from the paper motorcycle magazine I was writing for I tried a few other venues to publish my stuff. The pay was ridiculously low compared to the magazine and I stopped writing altogether as it didn’t seem worth my time. Most writers are a mix of hubris and insecurity; you need to think highly of yourself to suppose someone would want to read what you write. At the same time, deep down inside you need to be told you don’t suck at the job.

After a hiatus I pitched a story to Evans and he liked it. He told me he liked it, which was like crack cocaine to me. I needed someone to tell me I wasn’t washed up. I followed up the first story with several others. The pay wasn’t horrible and Brasfield made big of my efforts, swelling my ego to no end. In the comment section after my oddball stories Brasfield would write how fortunate he was that I submitted stories. When Brasfield said you were good enough you were damn well good enough. The guy was an absolute sweetheart and I felt like valued contributor.

Covid hit revenue for all businesses and overnight the economy collapsed like the house of cards it was. The Internet motorcycle websites were no different than the rest of the world. Brasfield told me in an email that they were dropping freelancers and going with mostly staff-written content. I didn’t like the news but at least he told me where I stood and we parted friends.

Hearing that Evans was killed in a motorcycle accident shocked me more than usual because he was such a vital presence online. I followed his Facebook page and we frequently exchanged comments. He was like a real life friend in that way. Everything I’ve read about Brasfield was positive and his own postings were typically positive. He loved his beautiful family and life must have been damn near perfect for him.

Motorcyclists live in denial. If we ever thought about what we were doing, putting a fragile bag of water atop a speeding, two-wheeled machine with next to nothing for protection, we wouldn’t do it. My feelings of “It could never happen to me” are gone now. If a good man and skilled rider like Brasfield can die in a motorcycle accident, any of us can. Hug your loved ones and enjoy the moment. Feel the warm sun and the cold rain. Look out at nature and marvel in your sentience. There are no promises in life and I wish I had known Evans Brasfield better.

Wayback Machine: British Motorcycle Gear Adventure Pants

By Joe Gresh

As any loyal reader of ExhaustNotes.us knows, I recently got all new riding gear from British Motorcycle Gear. In this blog we tackle BMG’s Adventure pants, a lighter weight alternative to BMG’s Pioneer pants. When I say lighter weight I don’t want to mislead you; the Adventure pants are still heavier than denim jeans.

The Adventures have two zippered vents on the front side that let in a lot of air when you stand up on the pegs like a real adventure rider is prone to doing whenever there is a camera around. Sitting down like a lazy chopper rider, the vent flow is less powerful but you can still feel it. There is a mesh liner that combined with the 500 denier shell gives a good compromise between protection and sweating.

One feature that stands out for me is the heat resistant, Nomex inner-calf panels. The high-mount, left-side Husqvarna exhaust system has burned a hole through several of my rain pants and street slacks. So far I haven’t been able to melt the Adventure pants.

Another feature I like on the Adventure pants are the three belt loops. I’d like to have a few more loops but three loops beat none because I wear a belt. You’d have to have a misshapen body like mine to appreciate the extra security a belt gives you in big-air situations. There’s nothing more embarrassing than getting pantsed by gravity.

On the sides of the Adventure pants are waist adjusters. These are handy for postprandial riding when your belly is bloated from too many carbohydrates. My odd combination of fat waist and short legs make finding motorcycle pants to fit a real challenge. I’ve been riding motorcycles for 50 years and the BMG Adventure pants come the closest to fitting in all those years. The 29-inch legs could be a 1/2 –inch shorter but as long as I have my belt it’s not a problem.

My Adventure pants came without armor, which is fine with me. I also have the much heavier-duty, armored BMG Pioneer pants to test but that will have to wait for cooler weather. The Adventures have long leg zippers but I didn’t need them to enter or egress the pant. If you are a weirdo who puts their boots on first, then your pants you will find the zippers handy. There is a short piece of zipper on the backside that can connect to BMG’s line of jackets. I never use those back zippers but I bet they stop drafts pretty well. The back zipper will also keep your jacket from riding up in a crash and possibly save a few square feet of road rash. Hmmm…maybe I should start using that zipper!

I’ve worn the Adventure pants down to 40 degrees with only a thin thermal underwear layer and was warm and comfortable. For my personal thermostat 40 to 80 degrees F was right in the Adventure pant wheelhouse. Above 90 and into the 100’s the Adventure pants are a bit too warm for my taste. Really, for motorcycle riding above 100 degrees shorts and flip-flops are the only way to go. Just kidding.

For New Mexico use the BMG Adventure pants are a great 3-season bit of riding kit. If you live where it rarely gets to 90 degrees or above then you can call them 4-season pants. I feel safer wearing them on a motorcycle than I do in plain old dungarees. The retail price is not out of this world when you consider the price of Levis jeans or cigarettes. Just punch in the code BMGJOES when checking out, and you’ll get an 11% discount on everything (except gear that’s already on sale, and Halcyon mirrors and goggles).  Check out the British Motorcycle Gear website; I know you’ll enjoy it.

ExNotes Product Review: Yamaha RD350 Kveldwulf Top End Replacement Set

By Joe Gresh

Parts for Yamaha’s RD350 are fairly easy to get but that didn’t stop me from hoarding a new top end set from eBay for the low, low price of $190. For that paltry sum you get two brand new cylinders, two brand new pistons, two brand new ring sets and two brand new wristpins with keepers. My buddy Bodden tried to warn me off the kit saying that the Teutonic name was a ruse and that Yamaha parts are far superior and I believe him. Still, $190 for an entire new top end? I had to bite.

First, there’s nothing wrong with my RD350; it runs great. I bought the Kveldwulf kit more as a spare and hedge against future scarcity. The kit is made in China; you know how international relations are going. We could be cut off at any moment. Unlike many people I don’t have a kneejerk reaction to Chinese products. I give them a chance to see if they are any good. In retrospect I probably should have bought an American made replacement RD350 top end kit (and I will if a company in the USA ever decides to manufacture one).

This particular top end kit has its problems. The biggest problem is that the right side piston won’t actually fit through the right side bore. The piston slides in about halfway and stops. Of course I could force it but the bike would only run a few minutes before it seized up. The left side is better but still feels a bit tight to me. What this means is I’ll have to have the cylinders bored to suit the piston size, a process that will probably cost more than the whole Kveldwulf kit.

The ports on the kit cylinders are sharp edged and dirty looking. I think I’ll need to chamfer the port edges before using the cylinders or the thing will probably snag a ring. It wouldn’t hurt to run a burr through the ports to knock down some of the roughness either. When I unpacked the box there were quite a few loose bits of aluminum sprinkled throughout.  A thorough cleaning is in order before bolting these parts onto my RD350. So the kit is not at a plug and play type deal.

The Kveldwulf pistons come with a Teflon-looking coating. I usually don’t like any of these new-fangled coatings and prefer plain old aluminum. I don’t have my RD350 apart so I can’t check the cut-away skirt and windows to see if the stock piston is the same. I’d also like to compare the ports to a stock cylinder to see how close the new stuff comes to original.

My best translation of Kveldwulf is “night wolf” and the prospects are indeed dim for this dog of an RD350 top end kit. I haven’t decided if I’m going to send it back and put up with that hassle or keep the kit and spend the time and money to remedy all its faults. I suppose if you had a RD350 that was missing its top end or it was severely corroded with broken fins the Kveldwulf kit would move you closer to the goal of a running motorcycle. You’ll have some sweat equity in the thing for sure.

If you have a stock RD350 and want to experiment with altering the ports but don’t want to mess up the original stuff this kit would be a cheap way to learn about two-stroke power bands without risking a ton of money. Then again, maybe I just got a dud. I’ll try to contact the eBay seller; they might take this top end set back and send me another one that is machined correctly. As delivered, I would only use the Kveldwulf kit as a last resort if my top end were totally wiped out, which is a hard thing to do with all the oversize pistons available. I’ll keep you updated whatever happens.
