Buell Fever Part 4: I’ve Struck Oil!

By Joe Gresh

Part of the reason I bought a Buell was because my life has become too predictable. Except for the Husqvarna, you stand a good chance of getting where you’re going on my old bikes. And the Buell is not disappointing. Lots of fun stuff is happening as I work on getting the bike back on the road.

It’s such a joy to tinker on a single-carb motorcycle. There are no racks and synchronizing to deal with, you only have to do a thing once instead of four times, but watch out for those aftermarket parts. The kit I bought was okay, but the emulsion tube was not drilled properly. And then I managed to pinch the bowl o-ring.  It was cheaper to buy another kit than a single bowl gasket, so I did that. Unfortunately, that kit’s bowl o-ring was too small. No matter how I stretched it, it kept popping out of the bowl groove. I ended up reinstalling the pinched o-ring. It was a futile effort to keep my mechanical standards up.

It wouldn’t be a Harley without baling wire. The choke tube is plastic and was fragile after all these years. The choke knob was falling out of its slot. I broke the tube finger tightening the thing. Wire to the rescue!
The accelerator pump plumbing was clogged. I fished a small bit of wire through the passage to clear it.
The carb kit emulsion tube (right side) was not drilled correctly. I try to use all the old stuff if possible. So this was no great loss.
This brass nozzle sprays fuel from the accelerator pump. Supposedly the tube is removable for cleaning but it seems well stuck and I started to chew it up a bit so I stopped.

I’m a big fan of lithium batteries, so I bought a Vevor brand close in size to the original lead-acid battery. The Vevor was a bit small and the factory battery location is not far from the rear cylinder exhaust header. To help with the heat I wrapped the sides and front with foam, then wrapped gorilla tape around the mess to hold the foam insulation.

It looks a little rough but an insulated battery is a happy battery.

A neat feature on the Vevor is the dual posts (four total). There are positive and negative posts on both sides of the battery; if your cables are in the wrong place, just flip the battery around. I added a spacer on the hook side of the battery strap to keep it tight and a small tube spacer in the bolt side (less threading to do on the hold down bolt), which makes installation 12 seconds faster. When you ride a Buell every second counts. The battery seems secure; hopefully, it will stay put.  With the Vevor battery (supposedly 400 cranking amps) in place and the carb back on, I needed to hear the Buell run. The oil tank level was between the high and low marks. The oil looked clean, like it had just been changed.

I removed the spark plugs, put the coke machine key in the ignition, and spun the engine over to clear any excess oil from my previous cylinder lubing. With the sparkplugs back in the cylinder heads I pulled the choke, hit the right turn indicator button, and nothing happened.

Harley handlebar switches are so weird. Pushing the starter button on the inside of the blinker switch worked better, and the Buell fired up in a couple revolutions. The engine popped and farted a few times. Lots of smoke came out the tail pipe but all things considered, it was running good.  Then came a loud pop followed by a geyser of oil spewing from the oil tank. The oil broadcast in a 15-foot fan covering the general area with great dollops of thick oil. The spots were viscous, so they stood proud of my clean concrete floor. Except for the spot I was standing. I received a blast of spraying oil that covered my sweater and left a clean, Joe-shaped silhouette on the concrete floor.

My nice, clean floor got its first baptism-by-Harley.
My nice, clean floor got its first baptism-by-Harley.
My sweater took the brunt of the oil explosion.

What a mess. How long the Buell had been sitting was unknown, but the oil tank must have slowly drained into the crankcase.  Some helpful person topped off the tank with fresh oil and I squirted the stuff all over the place. I drained the tank.  There must have been a gallon in there if you include the oil on the ground.  Once the oil level was correct, I fired the Buell and it settled down to the hit and miss syncopation Harley likes to call idle.

Back to other issues. I didn’t like the way the muffler was held into the bike. The setup relied on the front clamp combined with two rear brackets that bolted up in a parallelogram-like deal. The only thing that held the muffler in place was fastener tension.  To achieve a more secure mounting I made a thicker bracket out of mild steel and welded it to the Muffler. Now in order for the muffler to slide back my crappy weld would have to break. Which it just might.

Since I don’t have the equipment to weld stainless steel I made a mild steel bracket for the muffler.
The bracket welded to the muffler. Now the muffler can’t work loose and rub the tire.

The rear brake on the Buell was stuck. There were several issues contributing to this problem. The first was the brake pedal. It was bent where the master cylinder pushrod attached in a way that made the rod move dramatically sideways when the brake was applied. I used Harley tool 0-U812 (a big crescent wrench) to adjust the brake pedal. Now the push rod moved in a straight line concentric with the master cylinder.

This replacement rear brake assembly was close but off in meaningful ways. The seller refunded my money and didn’t want me to ship it back.
This part of the brake left was bent causing the master cylinder pushrod to go off course.
It’s still a little bent but the pushrod articulates correctly now.

The clone master/slave kit I bought on Amazon that was supposed to fit was just off enough to be completely useless, so I decided to rebuild the original stuff.

All the original brake parts cleaned up well. So far no leaks.

The piston inside the master cylinder was stuck but a few raps with a hammer had the piston moving and I dismantled the master/slave. I was having trouble finding seals for the Brembo components, so I cleaned everything and reassembled the brakes.

Bleeding the brakes wasn’t going well. I could get pressure at the banjo bolt on the master cylinder but nothing at the slave. Shooting brake cleaner into the brake line did nothing. The hose was clogged.  Out came the battery to access a hose clamp bolt, and I removed the brake line. Removing the brake light switch gave me a mid-point spot to shoot cleaner. The metal brake line was clear, the clog was in the rubber line.  I soaked the line in an ultrasonic parts cleaner then worked a 0.30 flux core welding wire through the rubber line. It took a bit of finagling but the wire made it through. Then it was just a matter of soaking with brake cleaner and shuttling the 0.30 wire back and forth until the line was clear. Blowing the lines with compressed air got rid of any stragglers inside the hose.  A quick reassembly and I had pressure to the slave. Bleeding the system was a straightforward proposition. The rear brake works.

Next on the list is fixing the kickstand and broken clutch lever.

Buell Fever Part 1: Give Me More Cowbell!

By Joe Gresh

As my age keeps creeping up and I slowly fall apart like Jeff Goldblum in the movie, The Fly, there is an urgency, a panic lying just below my normally placid exterior. Time is running short for all of us and if you have unfulfilled dreams, it’s best to get a move on.

The ill -fated VR1000, inspiration for my Buell’s paint.

Owning a tube frame Buell has been on my wish list since the S2 model came out in the mid 90’s. The combination of modern sport bike and 1957 lawnmower engine had a strange appeal to me and let’s face it: everyone should own a Sportster.

The dawn of 2026 found me frantically searching the internet for a 2000+ Buell Cyclone and I found a few. Several were pretty beat up all were reasonably priced but far away.

The deal I missed due to my inherent thriftiness.

I happened upon Iconic Motorbike Auctions and they had a pile of Buells from a private collection. The crown jewel was a Cyclone with only 6 total miles. It was a brand new, 25-year-old motorcycle.  I bid on the bike and it made reserve at $4,000. What a deal! $4K was out of my self-imposed Buell budget so I stopped bidding. Someone got a hell of a deal.

Next up at Iconic was a clean, Buell Ulysses complete with Buell saddle bags. It was a gas-in-frame model. I prefer a tube-framed Buell but bid on the Ulysses anyway. It sold for $3,250! I didn’t bid anymore on it because it just wasn’t the bike I wanted. Although if I got it for $2K I would have learned to love it.  After that, Iconic had an S3 with saddlebags that went for over $5,000. Now I was starting to freak out. I had Buell Fever bad-like. What if I was witnessing a Buell market correction in real time?

It’s like getting two bikes in one! Orange on the right.
And black on the left.

Iconic has a buy-it-now section for motorcycles that don’t make their auction reserve. I plundered around in buy-it-now and found a beautiful 1995 Thunderbolt with only 13,000 miles for $3,000. It has a few minor issues to sort out like any 30-year-old motorcycle but what really got to me was the Harley VR1000-tribute paint scheme . It looked cool as hell. I loved the paint job. I pushed the button.

It’s not an actual Cyclone, but it mostly is a Cyclone. The main cosmetic difference is the front forks and faring. Also the 1995 Thunderbolt used a bone-stock Sportster engine that Cycle World dynoed at 65-ish horsepower. Later Buell’s were pumped up a lot with Buell-specific heads and other parts churning out 100 horsepower.

While I wouldn’t mind another 35 horsepower, the truth is I just putt around on bikes. My go-fast days are behind me much like the strange growth I had cut out of my back a few months ago (see The Fly with Jeff Goldblum).

One advantage to the Sportster engine is that parts availability should be excellent for the remainder of my life and beyond. If I truly need more oomph there are tons of Sportster hop-up parts and 60 years of institutional knowledge on the Internet. 75 horsepower is a pipe and cams away.

But I probably won’t do anything to the Thunderbolt except ride it and look at it. I’ll be fixing the minor issues right here on ExhaustNotes so you’ll be able to follow along with this Buellishness.

Got to go. Driving out to Panorama City in California to pick up my dream bike from Iconic motorbikes.

ExhaustNotes Review: Kemimoto Heated Grips

By Joe Gresh

Old Man Winter is taking his sweet time here in New Mexico. It is late December, 70 degrees and the frozen old git still hasn’t made much of a dent. But he will arrive and I’ll be ready with my new Kemimoto heated grips.

I’ve set up the Kawasaki ZRX as my cold weather bike with a 12-volt receptacle for an Aerostitch heated vest and these grips will complete my preparations for the cold. If it ever gets here.

Installation would normally be simple as the wiring connects directly to the host bike’s battery. The main problem with this setup is if you accidentally leave the grips on and drain your battery. In the cold.

I couldn’t find an unused, switched power connection on the factory harness so I rigged a cube-type relay under the headlight faring that energizes from the instrument light circuit. This ensures the grips are off when the key is off. Power for the grips comes from the Areostitch vest power lead and runs up to the relay.

The heating elements just wrap around your existing grips and a 3-power level switch needs to go somewhere. I used a fairing mount bolt to secure the included switch bracket on the right side of the gauge cluster. It’s not a great location but it was easy.

Heat-wise these grips crank it out. On high you can feel the burn. This setting would be good for freezing weather. Low was still too hot during my 60-degree test ride so it should be good for average New Mexico winter conditions.

That wrap around heating element never really gets very tight on the grips so you’ll need to reset its position as it slowly creeps around the throttle. Or squeeze tighter.

The on-off switch is dimly lit so in sunlight it’s hard to tell what power level the thing is set at (red=high, blue=medium, green=low) I had to stop and cup my hand over the switch to see the illumination.

While I haven’t tested the grips in truly cold weather I’m sure they will help. It’s nice to pop the switch on when the elevation climbs over 7000 feet. Cuddly and warm best describes the feeling.

How long the grips will last is anyone’s guess but they’re easily unwrapped, unplugged and stored for the 10 months a year they are unnecessary in sunny, warm New Mexico. The harness, relay and switch remain on the bike full time.

I’m satisfied with the Kemimoto heated grips and give them a solid 3-star rating, a rating that could be improved if they fit the grips tighter and the switch was brighter. Maybe a section of elastic would help hold the grips better but what do I know. Now if Old Man Winter would get off his butt I could try them out in proper conditions.

Phavorite Photos: Luoyang Nightrider

By Joe Berk

We’d been on the road for about a month, riding a big loop through most of China.  It was the ride of a lifetime, Zongshen was picking up the cost, and we were having a ball.  It was me, riding compadre Joe Gresh, and Sergeant Zuo, our fearless retired Chinese Army Sergeant Major.  I’d be hard pressed to identify any other single month in which I’d so much fun.  Great riding, great companions, great roads, great food, and great photo ops.  My book , Riding China, is about that ride and it included a chapter on Luoyang; here’s a quote from it leading up to the photo above:

It was dark when we walked home, and I watched people riding by in the sultry summer night air on their motor scooters.  I knew I had to capture at least some of it for the blog and for this book, so I went back to the room for my Nikon and the 24-120 lens.  I cranked the ISO up to 3200 and let her rip.  It was great.

The technique is called panning; you swing the camera to stay on a moving subject, which freezes the subject and blurs the background to convey a sense of motion.  Not every photo turns out using this technique, but when one does, it’s spectacular.

We stayed in Luoyang for two nights, and it was a well-earned rest we all needed.  Those were good times.  I miss the guys we rode with.

The above photo is one of many included in Riding China.  If you would like to read more about that ride, pick up a copy!

Ural II

By Joe Berk

I don’t know much about Urals.  I had a chapter devoted to the brand in the Police and Military Motorcycles book because their motorcycles kind of had a military flavor to them, I would see a Ural at the annual Griffith Park sidecar rally here in LA (it belonged to a guy who had swapped an 800cc BMW engine into it), and our good buddy Dan from Colorado had one (I knew Dan from the CSC rides into Baja).  I guess the other thing I should mention is that we often sold CSC Mustang seats to Ural owners because the wait for a seat from Ural in Russia often took a year or more.  On occasion when I’d hear the latest news about Putin’s military misadventure, I would sometimes wonder how that affected Ural Motorcycles.  They were always a super-small niche marque; I reckoned that they probably weren’t selling anything since that stupid war began.

I guess I was right, as an email I recently received from Ural shows.  Ural is taking a different tack:  They’ve pretty much dropped the Russian-made WWII BMW clones (Ural moved to Kazakhstan, but to me, that’s still Russia), and now they’re hooking up with a Chinese manufacturer to make a smaller sidecar-equipped 500cc twin.  They’re calling it the Ural Neo.

The 500cc Ural Neo. Projected list price is “under $15,000.”

Man, talk about stacking the marketing cards against you:  A smaller displacement bike, a bike from a Russian (sort of) company,  a bike made in China, and catering to the sidecar market (when was the last time you saw a bike in America with a sidecar?).  I’m guessing they will be pricey, too, but hey, what do I know?

I have no idea how I made it onto a Ural email list, but here’s the letter from Ural:


Dear Friends,

If you know our history, you know this brand was never built in comfort. The challenges of the last five years and especially the move to Kazakhstan have made the legacy Urals impossible to produce sustainably. This led us to the decision to pause manufacturing of the new legacy models for export markets. It does not, however, mean that Ural is stopping. Instead, we are pulling (yet another) one-eighty in order to keep moving forward. Below is a letter from Ilya (a long read), that explains where we are, how we see the path forward, and the answers to some of your questions and concerns.

For new subscribers – welcome to the community! You caught us amid a big change. If your interest is solely in our legacy machines, please check inventory to find models that are still available at dealers in US, Canada and Australia. If you are interested in sidecars in general, feel free to subscribe to updates on Ural Neo.

For those of you who have followed the story for a while, our customers and supporters, we know this transition is not easy, and we don’t take your trust for granted. We want you to know that every decision we’re making right now is with your experience, your bikes, and your future support in mind.
Thank you for your patience and for sharing your stories, they keep us going every single day.

We wish you and your close ones a happy Thanksgiving and a happy upcoming holiday season!

Stay tuned for new developments.

The Team at Ural


A Letter From Ilya

“Dear Friends,

It’s been a while since our last update. Much of our time was spent on reorganizing the company and evaluating what is possible that would allow Ural to continue into the future. The complex challenges we faced required difficult decisions, sharp turns in direction, and more than a few leaps of faith.

Our recent post on our Facebook page – inviting riders to test-ride the new Ural Neo at one of our dealers – received a lot of attention. As with every mention of Neo, it brought out not only curiosity and support but also strong emotions, questions, and criticism.

We understand where those emotions come from. For most of you, Ural isn’t just a motorcycle – it’s a part of your personal story, the same way it’s a part of ours.

I still struggle to find the right words to describe what happened to Ural when the war began in 2022. The best way to describe it is this: it felt like our factory in Irbit had suddenly exploded. We had to make decision quickly. Some voices suggested stopping altogether, but this thought was dismissed almost immediately. Instead we moved final assembly to Kazakhstan.

This allowed us to continue building bikes. However, operating between two countries – one under sanctions and another with almost no infrastructure for a business like ours – proved to be extremely complicated. By late 2024, it was clear that this setup couldn’t last: we were losing money with every bike we built.

That’s when the idea of a lighter, street-oriented sidecar motorcycle in a different price segment began to take shape. Our original goal was to broaden our lineup and make better use of the infrastructure we still had. At the same time, we were searching for a longer-term solution for legacy bikes: exploring new suppliers, alternative assembly locations, and possible partnerships.

Then, in April 2025, the tariffs hit. Now not only was manufacturing inefficient – selling our motorcycles in our main market, the United States, had become nearly impossible.

Building in China and Staying Ural

When we started looking for ways to continue, we knew exactly what we didn’t want: to become a badge fixed on someone else’s product (and yes, we did have such offers). We wanted partners who understood sidecars and were willing to collaborate.

That search led us to Yingang, a family-owned motorcycle company with decades of experience making sidecar-equipped models for their local market. Their capabilities and willingness to work with us to refine the product made them the right fit.

Together, we began developing what would become the Ural Neo 500 – based on an existing platform, tested and refined with our input and oversight, built to our specifications and quality requirements.

What Ural Neo Is – And What It Isn’t

Ural Neo is not meant to replace our legendary 2WD sidecars. Legacy Urals gave generations of riders the kind of experience no other motorcycle could offer.

Neo is different. It’s modern, light and by far more approachable. It’s designed to bring new riders into the sidecar world, not to take anything away from those who already love it. If the 2WD models were still part of our lineup, Neo wouldn’t compete with them — it would complement them. Instead, it now continues Ural’s story in its own way.

Think of Neo as a bridge between Ural’s past and its future – a way to keep Ural’s name, spirit and know-how alive while we’re reinventing the company for the opportunities and challenges ahead.

Now let’s address some of the big questions.

Is production of classic Ural 2wd bikes stopped permanently?

We call it “put on pause”, which in plain English means we don’t know. What we can say with certainty is that we haven’t written it off entirely. The key for restoring the production, if it ever becomes possible, is to maintain documentation, equipment, tooling and, most importantly, our experienced engineers and skilled workers. We will be doing everything we can for as long as we can to support this infrastructure.
What’s going on at the factory in Irbit?

The Irbit factory is operational, although with a smaller team. Currently the factory is assembling a limited number of bikes for domestic market from existing stock of parts and components, and making spare parts for exports. The factory also performs contract assembly for a local vehicle manufacturer. The team in Irbit continues to work relentlessly to bring more business to the factory.

What’s going on with parts supply?

No sugarcoating here – the situation is tough. It’s hurting our reputation and the hard-earned trust of our dealers and customers. Parts are still coming to the country, but not in quantities or the regularity we need. Mainly it is caused by two factors: limited financing (especially when dealing with suppliers who require large minimum orders) and extremely complex logistics. We’re doing what we can to stabilize the supply chain, but realistically, it won’t improve overnight. The success of the Neo project will play a major role in helping us rebuild a reliable parts flow for all legacy bikes.

Why not move production to the U.S.?

We explored this and many other options, the numbers just don’t work. The replication of the manufacturing infrastructure would require multi-million-dollars investments. Even setting up an assembly in the U.S. is not feasible at this time, as logistical costs, wages and the costs of maintaining the facilities would drive retail prices out of reach for most riders.

Why in China?

China is the largest motorcycle manufacturing base in the world, with a vast ecosystem of specialized suppliers of parts and components. No other place in the world can manufacture sidecar bikes of comparable quality and as affordably priced.

The Neo 500 is built in China because it’s the right choice today, not because it’s the only choice we’ll ever make. As the project grows, we will continue to evaluate where and how future models should be built.

You shouldn’t put the Ural name on anything that isn’t original bike.

That’s exactly why this project is called Ural Neo. It’s a new chapter, and we fully acknowledge the difference. The alternative was losing Ural altogether. We’d rather see the name move forward than carved on a tombstone. We hope you would too.

The main appeal of Ural was its classic look. Without that vintage charm, who’s going to buy your new bike?

We know the Neo’s design and overall direction of the company don’t match what many of our long-time customers expected. But we don’t believe that appeal of the sidecar bikes begins and ends with nostalgia. A new generation of riders is discovering sidecars for different reasons – shared experience, practicality, and curiosity. Ural Neo is built for them – let’s give them a chance to decide if there’s something there.

How is Ural Neo financed? Why Ural is spending money on new project instead of supporting existing customers?

Ural Neo is structured, financed and operating independently from legacy business. A small group of long-term partners and investors – people who believe in the brand and in our team – provided the initial capital to develop, homologate and bring the new model to the market. We’re finalizing an additional funding round to ensure Ural Neo is set for successful launch.
When will we see Ural Neo at dealers?

The EPA/CARB certification unit is already in the country and we’re starting the certification tests in a couple of weeks. Additional demo units will arrive in the US late January – early February, and we’re planning demo-tour for February – April. The first production units are expected to start reaching dealer floors late May. We’ll share timelines and updates as we go.

***

We know the past few years have tested everyone’s patience and faith in Ural. But through all the challenges our goal hasn’t changed: to make sure Ural keeps going. Ural Neo doesn’t erase our history – it keeps our story, and yours, alive.”

— Ilya Khait
President, Ural Motorcycles


Will the above approach work for Ural?   Hard to say.  I think they’ll sail through the EPA/CARB certification process (China’s emissions requirements are tougher than ours).  The cost and marketing challenges will the toughest hurdles, I think.  Here are a few things they can do based on our success at CSC with the RX3:

    • Bring in enough spare parts to build the things.  That was one of the biggest concerns RX3 buyers had, but it was non-issue.  Steve brought in enough spares to cover any need.  That quickly put the spare parts issues to bed.
    • Be enthusiasts, spend a lot of time on the bikes yourself, and blog the hell out of your rides and adventures.  A lot of people followed the CSC blog, and that blog sold a lot of bikes.
    • Offer free online maintenance tutorials for your bikes.  CSC did, and it became a strong selling point.
    • Sponsor a cool ride every year for your customers.  We did that at CSC with the Baja rides, and people bought the RX3 bikes just to go on those rides.  It was great, it built a real community, and it gained us a lot of coverage.
    • Keep the price low.  People aren’t going to stand in line to pay a premium price to a Russian motorcycle company for a motorcycle made in China.  I read that Ural is projecting a list price “under $15,000.”  Good luck with that.

Probably the most significant factor and the best advice I can offer is to keep the price low.  The second most significant one would be the company rides; they did a lot for us to prove our bikes’ reliability and to quickly build a community.  Here’s one of my all-time favorite videos; it’s the one from our very first CSC Baja ride.

If you would like to read more about CSC’s marketing strategies in bringing the RX3 to America, and those sponsored motorcycle rides mentioned above, pick up a copy of 5000 Miles At 8000 RPM.  Don’t wait for the movie.

¿Quantos Pistones? (The Sevens)

By Joe Berk

I thought I could skip this one in our ¿Quantos Pistones? series.   After all, who ever thought there could be a 7-cylinder motorcycle?

But I was wrong.  Much to my surprise, there are actually at least a couple of 7-cylinder motorcycles out there.  I’ve never seen one, but they exist.  One is comparable to the 5-cylinder machine based on the Kawasaki two-stroke engines; the other is an aircraft radial-engined affair.

The JRL Cycles Lucky 7 used an engine originally intended to be a replacement engine for aircraft that used a radial engine.  They only built four of these (one prototype and three production bikes).   It’s an interesting footnote in any discussion of motorcycle powerplants, I guess.  But the thing looks goofy to me, and its chopperesque ergonomics pretty much guarantee it would be unrideable.   You can read more about it here: JRL Cycles Lucky 7 – A Radial Engined Production Motorcycle

The other motorcycle I found online with a 7-cylinder engine is the aforementioned Kawasaki.  Here’s a video that does a good job describing it:

The real treat in the above video arrives in the last minute or two, when you can hear it run.  It’s worth watching.

So what’s next?  Have much milk is left in the cow?  Have we exhausted all possible motorcycle engine configurations in our ¿Quantos Pistones? series?  Nope.  Stay tuned…the Eights are coming up!

ExNotes Battery Teardown: What’s Inside a Lithium Battery?

By Joe Gresh

You’ve probably read the story of my new, solar, mondo lithium battery bank. It consists of 16, 12-volt, 100ah lithium batteries and so far is working well. What you don’t know is I actually have 17 lithium batteries.

This one was dead on arrival. Before tossing it, I decided to see what’s in the box.

When I ordered the batteries one of them was dead on arrival. Like zero volts. This is a huge red flag because the LiFePo battery is know for its ability to hold a charge for long periods of time. I tried connecting a battery charger to the thing but all I got were sparks.

CT contacted the seller and they said it’s normal and to jump the battery with another (good) battery. I tried that and got even bigger sparks. The thing was shorted internally. CT went back and forth with them, and they wouldn’t send another battery. They did give us a refund, though, so it was all good and I bought another battery of a different brand.

Once the new bank was online and operating well, I broke down all the shed-filling, cardboard packaging for 17 batteries and hauled it off to the La Luz dump (a very fine dump). This left me with a lone, dead lithium battery. I was going to toss it out anyway, so I decided to open it up and see what a lithium battery looks like inside.

The top part of the battery box snaps into the bottom but I didn’t know that, so I set the circular saw to about 1/16″ depth and (after taking the battery outside in case it burst into flames) cut the top off.

The top part was still attached.  I didn’t want to cut any deeper because I had no idea what was inside. Wedging a flat-head screwdriver under the saw-cut lip and working it around the perimeter of box released the lid. Turns out I didn’t need the circular saw. After removing the lid, the internal parts easily slid out of the box, all in a nice, neat tray.

Once the thing was apart the problem was obvious. Both the positive and negative wiring to the output posts were shorted out on the big, metal plate.  The shorted metal plate covers the battery monitor circuit board.

This is where the battery was shorted.
Insulation chafing on the positive side.
Another shorted area.

The negative switch is how the battery monitor connects the internal bits with the external world. Over charge the battery? The battery monitor switch switches it off. Short out the battery? The battery monitor switch switches it off. Drain the battery too low? The battery monitor switch switches it off. For all I know there’s a high/low temperature cut off in the thing.

The heart and soul of the battery are these four big 3+volt, 100ah cells wired in series by those welded jumpers.

It turns out whoever built the battery put the terminals to the output posts on upside down. This moved the barrel/crimp part of the wire connection that much closer to the metal plate.

Under the metal plate sits the battery monitor system board. It connects to each individual cell and also saved the battery from bursting into flame from the short circuit.

All things considered, if you’re going to screw up the battery this was the least damaging way to do it. Since the + and – were directly shorted before it got to them, the electronics and lithium cells weren’t involved the short circuit. The battery monitor system kept the thing from burning up due to the short.

I added a bit of insulation to the burned areas that were shorted.

Once the lid was off and the source of the short removed, the battery showed voltage again. Pretty cool. I gave the battery a charge and all seemed normal. I load tested the thing at 100 amps and it held voltage fine. You know what this means.

The fix was as easy as flipping these connections 180 degrees. Photo shows the connection already flipped. The other way they contacted metal.

The fix was as simple as flipping the wire terminals over allowing that extra 3/16″ clearance. I reassembled the guts into the battery and snapped the lid back on and now I have an extra, good lithium battery. While technically it’s a free battery I have some time in the repair. Now I know what’s inside the black box. I’ll probably run some gorilla tape around the box so the iffy lid attachment stays put and call it a win.

ExNotes Solar Series: Lithium Batteries

By Joe Gresh

I finally made the leap. My solar system went online in 2018 and except for a few snow days has produced reliable power in all that time. We’ve had around 30 power outages at the grid-tied Carriage House (some 5 minutes, some 5 hours) during the same time span.

The old, lead-acid bank gave great service but it is time to step into the future. I’ll be keeping the best of the old ones for a power source in the green house.

Initially we went with plain old lead-acid batteries because they were a third the cost of lithium batteries. The lead-acids worked well and since they’ve been around hundreds of years it was easy to predict performance and longevity.

The jumper cables are messy but effective.
The old bank was four boxes on two shelves. I never did get around to filling the last box.

The battery bank started small with just 4 batteries and grew with our budget to 12 total. There are two of the original 2018 batteries still functioning and I’ve replaced three batteries that failed. It’s easy to tell a bad lead-acid in a battery bank: it’s the hot one.

I haven’t been religious about topping up the electrolyte so some of the batteries might have failed due to misuse. Regardless, I’m happy with their performance and the lead-acids did me right.

Last year I noticed lithium batteries dropping in price. They ended up costing the same as the cheap Walmart lead-acids I was using. With new tariffs looming I decided to make the switch. I bought one batch in January and another batch in March, depending on whatever sale was on. My cost averaged around $119 per 12-volt, 100-ah battery. I wasn’t brand loyal, whatever was cheapest was fine by me.

With winter approaching and long cold nights of pipe heaters draining storage I built an insulated box to hold the new batteries. Advantages with the lithium are 16 batteries fit on one shelf, weight is half of lead acid, and there’s no need for a sealed battery box as there’s no acid to leak.

Most of this was replaced by copper bars.
Lots of copper buss bars took a couple days to make. Foam on top to prevent shorts in case a chunk of metal lands on the bank.

I also took the opportunity to clean up the installation, getting rid of messy-looking jumper cables and replacing them with solid copper buss bars. With everything on one shelf I eliminated several feet of cabling which can only be good.

Lithium batteries need a bit more charging voltage so I cranked up the solar regulator a 1/2 volt or so. I also reset the inverter charger setting to one more like lithium.

The batteries have sat on the shed floor for 6-8 months so when I connected them up to the solar they sucked a steady diet of 55 amps from the sun.

Theoretically I have 19,000 watts of storage now, more than double the 7200 watts of the old, lead-acid battery bank. In actuality it’s probably 80% of 19,000 watts because you don’t want to drain the batteries flat.

The new box is 1-inch foam skinned with sheet metal. Hopefully it will slow a fire.
All the batteries on one shelf cuts down on cabling. Buss bars make a tidier installation. With no acid fumes connections should stay cleaner. What’s not to like?

Some disadvantages to lithium batteries are they are more affected by cold temperatures (hence the insulated battery box), they are limited to 100-amp output per battery (not a problem as my inverter draws 250-amp max), and I can’t really think of any others.

Time will tell if the lithium batteries last the 10-year claimed life span. I’ve pre-tested each battery’s load capacity and marked the results on top of the battery. I should be able to compare results in the future to see if individual battery performance degrades. All in, I’m happy with the new batteries. Hopefully I’ll have about a 3-day reserve for those snow days.

Oh, and those tariffs? They don’t seem to apply to lithium batteries as you can still get 12-v, 100-ah lithiums for $119 on Amazon.

Citizen Green

By Joe Berk

You’d think with my old-age eyesight and need for bigger letters and numbers I’d wear the Citizen watch you see above more often, but the fact is I don’t.  I bought it years ago when I was a yuppie, and I wore it a little, but it just hasn’t had much wrist time in the last couple of decades.  But it still works well, and it’s still got those big numbers.  I need those now.

The Citizen uses their E101 solar-powered quartz movement and like all Citizens, Seikos, Casios, and Orients that use a quartz movement, it is phenomenally accurate.  I’m talking in the range of seconds per month.  I never thought I’d need a watch that accurate, and I probably don’t, but I enjoy having one.  It’s one of the reasons I almost never wear an automatic (i.e., mechanical) watch anymore.  They just don’t have the kind of accuracy I’ve become accustomed to.

Another feature on the watch you see here is the lume.  It’s incredible.  At night, the numbers and those big hands jump out at you.  Other than having a backlit Casio or Timex, the lume on this watch makes it one of the easiest to read in darkness I’ve ever owned.

Once this watch is charged after being in the light, it keeps running for a long time.  If I leave it on the shelf for months, it still keeps running.  Evidently, room lighting is enough to keep it charged.  When it does run down, it doesn’t take very long for it to come alive when it sees sunlight again.

What surprised me is that even though I’ve owned this watch for more than 20 years (it’s probably closer to 30 years), you can still buy this model at a relatively modest price.  The exact colors you see here are no longer available, but the basic watch design is, and to me the new colors are just as attractive as the old.  Here’s the same watch in a brushed stainless finish with a canvas strap.  I like this look a lot.

I’m tempted to buy the watch you see above, but I already have plenty of watches.  You can buy the above watch on Amazon for $184, or better yet, from Jomashop for a paltry $124.   That’s a hell of a deal.

The Bone Folders

By Joe Berk

I haven’t done a knife story in awhile,  but that doesn’t mean I haven’t been buying.  Some of these online knife stores’ websites are addictive, and the Chicago Knife Works site certainly falls into that category.  It’s fun just perusing their offerings.  Sometimes, I’ll see something that piques my interest and then I’ll search on a feature that a particular knife has.  That occurred recently when I saw a folder I likes with bone handles (or scales, to use knife aficionado terminology).

Bone as a scale material is intriguing to me, partly because I like the way it looks, partly because it looks like ivory, and partly because of a recent visit to the fabled Colt Custom Shop in West Hartford, Connecticut.  When I saw an artist crafting custom grips on a Colt 1873 Single Action Army, I asked about the material (knowing that ivory was no longer available).  The answer, as good friend and Colt factory guide Tim told me, was bone.  Giraffe bone, to be specific.  I would never have imagined.

Anyway, to get back to the main attraction, I saw a Marbles folding knife with white bone scales on the Chicago Knife Works site and I liked it, so I searched on all Marbles folders with bone scales.  What the site’s search returned was intriguing.

I liked every one of the knives I saw, and Chicago Knife Works‘ prices are so reasonable I pulled the trigger on all of them.  Cheap fun, and they looked good on the Chicago Knife Works site.  They arrived a few days later (all the above, with shipping, was only about $50), and I can tell you they look even better in person.

All the knives are appealing, and I like the white bone appearance.  The canoe style is one I’ve written about before, and in my opinion, it is about the perfect-sized pocketknife for pocket carry.  It has two blades and both are razor sharp.  The work knife (also known as a sodbuster) is a single-bladed knife and its name comes from the fact that it is designed to be used by a working man (like a farmer).  The trapper knife (as you might have guessed) is the design preferred by trappers.  It has two blades:  One with a clip point and the other with a spey blade (we’ve mentioned those before; my Case Stockman knife also has a spey blade).  And finally, there’s that gorgeous two-bladed sunfish knife, which is a big knife.  It gets its name from its sunfish-like shape.

The Sunfish is a physically big knife, as the following photos show:

I can’t say which of the above knives I like the best, so I’ll cut to the chase and tell you that I like them all.  So much so, I continued the quest for knives with white bone scales.

Most recently, I purchased a large folder (the Rough Ryder Deer Slayer) from another knife supplier only because Chicago Knife Works didn’t have it in stock.  I’ve written about it before.

I like the look and size of the Deer Slayer so much that I started poking around to see if that knife was available with white bone scales.  It was.  The manufacturer this time is Hen and Rooster, and I was able to order it from Chicago Knife Works.

I guess I should say the importer, not the manufacturer, as I suspect the same manufacturer makes knives for several importers with slight differences to meet the importers’ marketing strategies.  I don’t have the Hen and Rooster knife yet, but when I get it, I’ll post a few photos in a future blog.
