Fifty years ago I used to be a pretty good metallic silhouette shooter. I would like to return to that game. It would be nice to be 25 years old again, too, but that’s not in the cards. Metallic silhouette shooting, though…I think I can turn the clock back on that one.
If you haven’t figured it out yet, that’s where this story is going. Ponce de León went looking for his fountain of youth. Me? I just want to knock over a few metal chickens, pigs, turkeys, and rams. Like I did 50 years ago.
My friends at the range are surprised when I shoot at 100 yards with a revolver. That’s because they’ve never shot a handgun metallic silhouette course. In that game, there are four courses of fire:
Chickens at 50 yards (10 shots)
Pigs at 100 yards (10 shots)
Turkeys at 150 yards (10 shots)
Rams at 200 yards (10 shots)
The targets are sized so that each subtends about the same angle. That means the pigs (actually, they are supposed to be javelinas) are bigger than the chickens, the turkeys are bigger than the pigs, and the rams are bigger than the turkeys.
The hardest target to hit is the turkey (it is narrower than the other targets); the hardest target to knock over is the ram (it is big and heavy). Simply hitting doesn’t count; you have to knock the targets over. The 200-yard ram weighs about 55 pounds. Back in the day, I used to be able to knock them over with a .357 Magnum. My load was a 200-grain cast bullet and 13.0 grains of Winchester 296. It was more reliable than a 240-grain 44 Magnum load because the .357 bullet is more aerodynamic and it retained more energy downrange.
I’ve been evaluating loads for the .357 Ruger Bisley for metallic silhouette competition, and load development is progressing. I’ve mostly been playing with Hornady’s 158-grain jacketed hollowpoint XTP bullet, but I’ve also tried their 180-grain XTP. In my Bisley the 180-grain Hornady is a very accurate load.
The two bullets are identical above the cannelure. The difference is bullet length behind the cannelure.
I’ve been keeping track of the loads, the velocities, and the accuracy on 100-yard targets. The Bisley shoots best with the 180-grain Hornady XTP bullets and 13.6 grains of 296 powder. I used small rifle primers. I’ll try the same load with small pistol magnum primers to see if I get a velocity gain and if the groups get better. In prior tests with the 158-grain Hornady bullets, there didn’t seem to be a velocity increase in going from small rifle to small pistol magnum primers. We’ll see if the same holds true for the 180-grain bullets.
Here’s a 100-yard target with the actual size of the 100-yard pig overlayed on it. That silhouette is one I grabbed off the Internet. It is smaller than what I remember (and certainly smaller than any javelina I’ve ever seen, other than babies). But it’s useful for assessing my progress in getting a useable Bisley load. I used the 180-grain bullets for the group you see below.
Real javelinas are not quite that small, and they’re mean as hell. You don’t want to tangle with a javelina.
Winchester’s 296 powder is my preferred propellant as it usually gives great velocity and accuracy. Winchester 296 is prone to gas cutting, though. That’s what occurs on the underside of the revolver’s top strap (the part of the frame that goes over the cylinder). Hot gases and powder escape between the barrel and cylinder gap and cut into the frame. From what I’ve read, it tends to cut as you see in the photo below, and then it doesn’t get any worse. I think that’s because as the cutting gets deeper, the distance to the bottom of the cut increases.
I’ve seen gas cutting in handguns after putting lots of 296-powered rounds through them (and that’s what I intend to continue to do with the Bisley). We’ll find out if it is self-limiting.
The plan is to continue to practice (a lot) and continue the load development effort. So far, 13.6 grains of 296 and the 180-grain Hornady bullet get the nod. Then I have to zero the revolver at 50, 100, 150, and 200 yards. Fortunately, my club (the West End Gun Club) has a range that goes out that far. Then I’m going to find someplace that has handgun metallic silhouette shooting and knock down a few targets. It’s going to be fun.
This press release came in the mail a few days ago and I thought I would share it here.
ADV Cannonball Rally
A mix of curated motorcycle roads and a checkpoint rally for the ultimate cannonball rally, ADV moto style.
Port Angeles, WA — A new kind of annual adventure motorcycle event is in the works. It will take riders across the United States on amazing roads hand-selected specifically for riders. But this isn’t a tour – it’s a competitive GPS-based rally. Go for glory. Go for adventure.
The 2025 ADV Cannonball Rally will take place October 6-14, 2025. This year it will start in historic Kittyhawk, North Carolina on the Outer Banks and ends in Redondo Beach, California at the famous Portofino Hotel & Marina – a staple finish line for many cannonball rallies throughout history. This unique 3,550-mile experience is open to motorcycles of all types, will include nine days of riding, and has GPS-based checkpoint competitions located at epic places.
This coast-to-coast rally will have an emphasis on overland GPS navigation, endurance, preparedness, self-reliance, and rider skill. Aaron Pufal, the event’s organizer, says, “Each day, participants will leave the official hotel at specific times. Navigating by provided GPX tracks, competitors will ride on paved and optional unpaved roads to checkpoints, electronically earning points while experiencing a highly curated and painstakingly vetted motorcycle route.”
Pufal, an experienced rally planner and ADV moto enthusiast believes there’s a secret sauce to a good motorcycle road, and this route is carefully crafted by motorcycle enthusiasts for enthusiasts. The event will take riders through iconic, amazing locations—all with remarkable riding roads as the backbone. “This route isn’t for the faint of heart,” Pufal states, “but riders will appreciate the hundreds of hours of planning and prerunning.”
This isn’t a race; It’s a rally; and it’s self-supported. No team chase vehicles. No support crews. No whining. Riders must rely on themselves or any public resources available to any competitor to stay the course on the road to victory.
The ADV Cannonball Rally is a friendly competition. Here, riders are scored on their ability to reach specific checkpoints. Bonus points are awarded for the first rider to arrive at the next official hotel each day of the rally. Special achievements and separate extreme checkpoints revealed throughout the event will allow the chance to get a leg up on the competition with some extra points. The event is scored via a GPS app. The rider with the most points at the end is the winner.
Trophies will be awarded at the rally’s banquet for various achievements. The overall winner will have their name embossed on the ADV Cannonball perpetual trophy in perpetuity.
Entrants can be as competitive as they’d like—go for glory, adventure, or a bit of both. No rally experience? There will be opportunities for learning and guidance before the starting gun is fired, ensuring entrants understand how the competition aspect works.
Entries Are Limited: This event is open to the public. Anyone is welcome on any motorcycle. Current entries are exactly what you’d expect, big ADV bikes, but, we’d surely welcome the wacky, brave, or oddball entry!
Currently, we have enough paid signups to proceed with the event but we are limiting the entries to 30 hotel rooms for the 2025 rally.
Learn More: Complete info is available at the rally website, ADVCannonball.com. There, visitors will find the rules and regulations, interactive route map, FAQs, ADV Cannonball Podcast Links, and the official entry form. The ADV Cannonball Motorcycle Rally is sure to be an amazing journey. “Come have a good time,” says Pufal. “This is going to be for like-minded riders who are sick of sitting behind the computer and ordering accessories for their bikes—and definitely not for ADV Weenies.”
We’re seeking: Press interactions, sponsors, and partnerships in the ADV-Biz and motorcycle social media. We feel the inaugural running of the ADV Cannonball is a great story that deserves to be told.
It looks exciting. It’s worth considering. I checked out the website and it’s interesting reading.
Happy New Year, folks. I’m looking forward to a great 2025. We’ll keep the stories and the photos coming. You keep clicking on those popup ads and please consider making a donation via the Donate buttons below!
Those of you who subscribe to Motorcycle Classics magazine may have seen my article on good buddy Andrew’s Norton P11. I was very proud of that piece and its photos, until I found out that I got a few things wrong. The most significant faux pas was my description of the shift pattern, which I mistakenly assumed was the same as a Triumph’s. All my ‘60s and ‘70s Triumphs were one down, a half click up for neutral, and all the rest up (just like on most of today’s motorcycles). BSA was the same way. When I rode good buddy Steve’s Norton Commando of the same era it was one down and three up. That’s the natural order of things, right?
Ah, not so fast. Norton did it differently. On a Norton, it’s one up and three down. Just like it’s marked on the transmission. Just like my photo above shows.
So why did I get it wrong in the MC article? Chalk it up to old age and carelessness, I guess. I sure am embarrassed about it. I should stick to things that are harder to get wrong (maybe I should be a presidential election pollster for the New York Times).
You might be wondering: What about Steve’s Norton Commando, which had the conventional one down and three up shift pattern? As it turns out, more than a few Norton owners reversed the shift pattern on their bikes to make them like the rest of the world, which can be accomplished by installing a mirror image cam plate in the Norton’s AMC gearbox. That’s evidently what happened to Steve’s bike way before he owned it, and way before I rode it.
Guys who have the original Norton gearbox pattern write that it’s the more natural of the two shift patterns. When you want to go faster, you push down on the shift lever. It’s kind of like stepping on the gas, I guess. Foot down, go faster. Thinking about it, it makes sense.
You know, I didn’t think too much about the Norton’s controls layout when I wrote the P11 article (and obviously, what little thinking I did was not enough). I wrote another MC story about a 1913 Thor several issues back, and if I would have made a mistake, I would have thought it would be in that article. On that one, I had to study my photographs and think about what each lever, pedal, valve, and twist grip did (and there were a lot of each); there was no one to explain it all. After I had done that, I actually found a guy who owned a 1914 Thor (how many of them can there be?) and he told me I had it right. But on that Norton…I’ve ridden a Norton, I’ve owned a bunch of Triumphs and one BSA, and I just never thought I’d get it wrong. But I did. Mea culpa.
Oh, two more things:
Merry Christmas and Happy Hannukah. They’re both on the same day this year, which is very unusual.
That photo at the top of this blog? That’s the P11A, Andrew (on the left), and good buddy Harry (aka the Norton Whisperer).
I felt a mix comforting mix of “been there, done that” and smugness when I read the Wall Street Journal yesterday. The lead photo in the paper’s “Off Duty” section was strangely familiar, and as the coffee kicked in I realized it was because I’d been there: Colombia’s Magdalena River. My Magdelena photo (one of many) is the photo you see above.
The Wall Street Journal article featured places not part of the borscht belt (i.e., typical tourist destinations), and the stops it recommended along a Magdalena River cruise were locales I’d been to: Barranquilla, Cartagena, Mompox, Magangué, and others. I’ve been luckier than most because I’ve had incredible motorcycle adventures: China, Mexico, the Three Flags Classic, Baja, the Western America Adventure Ride, and more. The ride through Colombia and along the Magdalena River, though, was in many ways greater than the other motorcycle adventures. The Journal’s story had me thinking about Colombia again, and I thought I would share a few photos of the places it mentioned with you.
Mompox
Ah, Mompox. It’s pronounced and sometimes spelled Mompos…an amazing city, unlike any I had ever visited. The night we were there I wanted to stay in the hotel and post a blog for my CSC readers, but good buddy and ride leader Juan told me: Joe, your readers will wait. You need to see Mompox. He was right.
Magangué
We began our ferry ride to Mompox from Magangué (pronounced ma gong gay). It was brutally hot and humid and we had to wait a couple of hours for the ferry to arrive, but that ride down the Magdelana was worth the wait. Dreamlike, it was a scene from a 1930s adventure movie. Peaceful. Indiana Jones. That ferry ride had it all. There are more adjectives I could use, but you get the idea.
Barranquilla
I first saw Barranquilla (pronounced bar en key ah) on an earlier business trip to Colombia. I’d just purchased a new Nikon D200 (the cat’s meow back then), and it had a backfocus issue I later had corrected (you can’t see it in these photos, though). I felt like Indiana Jones at a beauty pageant. If there are unattractive women in Colombia, I couldn’t find them.
Cartagena
Yep, that Cartegena, the same one as is R0mancing the Stone (although that movie was actually shot in Mexico). On that same business trip, we took an afternoon to visit Cartegana, about an hour and a half down the coast from Barranquilla.
There were many things in Colombia well beyond what the WSJ article covered: Honda (the town, not the motorcycle), Covenas, Volcan Los Nevados, La Playa de Belem, Barichara, Villa de Leyva, and more. I saw them from my RS3 motorcycle (the carbureted version of the RX3) and you can, too, if you don’t mind living vicariously through my lens and keyboard:
Mike Venturino was one of the greatest gun writers who ever lived. Whenever I’d see his byline in a gun magazine, I would carefully read every word in the accompanying article. He was a guy who wrote about things that exactly matched my interests: Handguns, rifles, military surplus weaponry, reloading, reloading for accuracy, and more. His style was relaxed and friendly, and his writing was easy to follow and understand. I felt like I knew the guy, even though we had never met. His writing style, I’m sure, influenced mine.
Mike Venturino passed away recently, and FMG Publications assembled a collection of his articles originally published in American Handgunner magazine. As soon as I heard about Shooting Iron, I ordered a couple of copies on Amazon (one for me, and one for a good friend). If you like good writing, good storytelling, and all things firearms related, I think you should pick up a copy, too. You can order Shooting Iron here.
As I read through Shooting Iron, I came across two descriptions in which Venturino described blowing up a 9mm handgun. You may recall that I did the same, and I shared that experience with you here and here. Based on what Venturino wrote and what I experienced, I am rethinking my 9mm 1911 Springfield blow up. I previously concluded that I must have had a double charge in one of the cartridges (particularly because I was using a new turret press). Now I am thinking that wasn’t it at all, but it was instead the bullet being pushed back into the case. This is based on the following:
I was using powder coated Gardner bullets, which are very slippery. It’s would have been easy to push one of them back into the case if the crimp was not strong. I don’t know if I had a really tight crimp when I loaded the round that burst. I use a very strong crimp now. Back then, I don’t know if I did.
I checked about 1500 cartridges after that event (ones I had previously loaded but not fired) by pulling them apart and examining the charge. None were double charged. That doesn’t prove I didn’t double charge one, but it suggests it was unlikely.
In reading the articles in Shooting Iron, I found where Venturino describes the 9mm bullet pushback phenomenon in two places (when you buy your copy, take a look at Pages 32 and 63). On Page 32, he describes this having occurred with a 9mm round, and he shows a burst case that looks just like mine. He further describes this episode with “…the escaping gas spitting (he probably meant splitting) the two grip panels and stinging my hand.” That’s precisely what I experienced. On Page 63, Venturino shows a burst case that looks like my case. I don’t know if the two instances described in the book are the same event. They both sound like what I experienced.
The bottom line is I don’t know exactly what happened when I blew up my 9mm 1911 and I never will. But after reading Mike Venturino’s Shooting Iron experiences, I am more convinced it was a bullet being pushed back into the case. In either event (bullet pushback or a double charge), I’m guilty of careless reloading, but somehow messing up on the crimp makes me feel less dumb than double charging a case. And I especially feel less dumb knowing that one of my literary heroes (Mike Venturino) did the same thing.
The Harley WLA at the National Infantry Museum was a lot prettier than any other WLA I had ever seen, but I wasn’t impressed. It was way over-restored, finished in gloss OD green (something I had never seen on a WLA before). I couldn’t find anything in my research to show that any World War II Harleys might have had such a paint treatment. I found a reference that indicated Army administrative vehicles were sometimes painted gloss OD, but nothing about motorcycles.
I once saw General William Westmoreland’s Cadillac Sedan de Ville in Washington, DC, and it was gloss OD. But WLAs had been out of service long before that, and in any event, when I spoke with General Westmoreland he didn’t mention anything about riding motorcycles. If anyone out there knows anything about WLAs with glossy paint, please leave a comment.
Here’s a quick look at what I’ve found to be three Mosin-Nagant accuracy loads shot off the bench at 100 yards using the rifles’ standard open sights. I didn’t try to get too sophisticated for this quick comparison; I simply shot a 10-shot group with each load. All were at 100 yards. I used the NRA 25-yard handgun target because it’s what I had on hand (the bullseye on that target is slightly smaller than the 100-yard NRA rifle bullseye target, and it gave a decent aiming point). You’ll see the targets below.
My first two loads were with a rifle I use strictly for jacketed bullets. It’s my Tula 1940 round-top receiver. All you purists and keyboard commandos look away; this rifle is not for you. I refinished the stock with TruOil, I glass-bedded the action, and I reworked the trigger. As I’ve explained in earlier blogs, this rifle has a very rough bore, but the rifle remains blissfully ignorant of that fact and it shoots well.
I shot the cast bullet load in a Mosin-Nagant rifle I use for cast bullets. It’s a 1928 Ivshevsk hex receiver with a relatively clean (i.e., unpitted) bore. When I first shot this rifle with jacketed bullets, I found that it shot a foot or more above the point of aim at 100 yards with the rear sight in its lowest setting. I could have compensated for that by finding a taller front sight, but I decided instead to use the rifle with cast bullets. It shoots cast bullets within the rear sight’s adjustment range.
The Ammo
I shot 7.62x54R Russian reloaded ammo for this article. Two of the loads used jacketed bullets; the third used cast bullets.
The jacketed loads were identical other than the bullet and cartridge length: For one load, I used Hornady’s 150-grain polymer-tipped jacketed bullet; in the other, I used Privi Partizan’s 150-grain jacketed softpoint boattail bullet. I didn’t crimp either load, and I didn’t attempt to find the best seating depth. The seating depths I used, though, worked well. Both loads used a charge of 43.7 grains of IMR 4320 propellant.
The cast load used a 200-grain cast lead bullet with a gas check. I didn’t crimp the cast bullets, either, although I did use the Lee factory crimp die to remove the case mouth flare that prevented bullet shaving when the bullet was seated. This load used 18.0 grains of SR 4759 propellant.
The astute reader and reloader will notice that several of the components I used for these loads are no longer available. The Hornady polymer-tipped 150-grain .312 bullets went out of production some time ago, as did the IMR 4320 and SR 4859 powders. It’s annoying, because when I get a load that works, I’d like to be able to load it again. I’ve got a good stash of IMR 4320 and that will probably last me the rest of my life (it’s a powder that works well for .30 06 and several other cartridges). I’ve also got a good stash of SR 4759. That’s been a favored “go to” powder for cast bullet loads and reduced .458 Win Mag loads, and I’m working through it at a pretty good clip. Trail Boss and 5744 are two powders frequently mentioned as also being good for reduced loads and cast bullets, so at some point I’ll have to start developing loads with those powders. I’m probably good for the next two or three years with my SR 4759 stash.
The Results
To cut to the chase, here are the loads and the results:
The Hornady polymer-tipped bullet was the clear winner:
The Hornady polymer-tipped bullet put all 10 shots into a 3 1/2-inch group at 100 yards, which is not too bad with iron sights and geezer eyes. That’s almost a 10-ring-sized group (the 10 ring on these targets is 3 1/4 inches in diameter). I’ll call it close enough for government work.
The PPU bullets are still available, although you don’t come across them very often. Sometimes the big online reloading shops (MidwayUSA, Midsouth, Natchez Shooting Supply, Powder Valley, etc.) have them on sale, and when that happens, I’ll stock up. Here are two PPU-bullet, 10-shot, 100-yard targets:
Interestingly, the velocities of the two jacketed bullets (Hornady and PPU) were about the same. The Hornady bullet had a much larger velocity spread, but it turned in the tighter group.
And finally, here’s the 10-shot, 100-yard target I shot with cast bullets:
I was pleased with the cast bullet target, too. I wouldn’t ordinarily expect a cast bullet to group as well as a jacketed bullet, but these hung right in there.
So there you have it: Three loads that return acceptable accuracy in a Mosin-Nagant.
We have several articles on Mosin-Nagant rifles and on different loads for these rifles:
Boy oh boy oh boy! Talk about an interesting barn find! We all have regrets filed under “I shoulda bought that when I had the chance,” and in my case, one of those items is the Harley XR1000. I did a Dream Bikes feature on it a ways back, and as soon as I did, Joe Gresh let me know that he had been planning to do the same (I beat him to it).
I always thought the Sportsters had a cool look, and to me, the XR1000 was cool raised to an exponent. It did what it was supposed to in my mind: It evoked images of Bart Markel drifting around a half mile dirt track (which I actually saw many times at East Windsor Speedway when I was a teenager), and it made me want to be that guy.
On a whim, I typed “XR1000 for sale” on Google, and this popped up. Wow, talk about a barn find!
The ad text says it all:
2,486 ORIGINAL MILE INCREDIBLY ORIGINAL BARN FIND!!! Untouched “barn find” condition very original XR1000 in absolutely amazing condition! Although I am using the term “barn find,” this bike was properly stored in an attached climate controlled garage after being completely serviced and prepared for long term storage, including cylinder fogging, fuel draining, oil change, battery removal, and a full check over and service including: head and valve spring check by the Harley-Davidson dealer race program lead technician (back in the day), fork seals, brake fluid, chain lube, etc. We have tested all non-running systems including front and rear brakes, turned over the engine, lights, starter operation, horn, tires holding air, suspension compliance, etc. and confirmed all to be in proper working order. If the new owner would like us to fill the fuel tank and get the bike running, we would be happy to do that as well, or we will leave it as it is in “barn find” condition. It is up to the buyer’s preference. The condition of all the paint, chrome, and metal is excellent with only dirt and dust covering, no corrosion. The only slight surface corrosion I see is limited to the exhaust heat shields only and could easily be remedied. The rest of any “rust colored” things you may see is simply dirt that I have confirmed in a couple small spots will clean off. Of course, I can’t say the bike will look like brand new with a simple wash after sitting for 20 years, but I am saying the chrome and trim IS NOT corroded. The bike does come complete with 2 keys (one ORIGINAL Harley key), books and manuals, and some records from the Harley Dealership when it was gone through and fully serviced and readied for storage in 2005. The bike also comes with the original longer black mufflers, while the optional accessory shorter less baffled mufflers are currently installed on the bike. We purchased the bike directly from the previous older collector owner as part of a seven Harley-Davidson collection and rolled it out of his garage into our enclosed trailer and brought it here for inspection. I have described everything to the best of my ability and provided lots of detailed photos and information for your consideration. Please feel free to contact Jason for any intelligent unanswered questions if you are interested in purchasing the bike. Without a doubt an incredibly rare opportunity to own a piece of Harley-Davidson history, and the only one like it for sale nationwide.
Wow! Somebody buy this before my “Want” overcomes my “Need.” Will it get away? Man, $27K sure is a lot of money. But how much is $27K these days of $4/gallon gasoline and runaway inflation, anyway?
Like I said: Wow! Will there ever be another opportunity like this?
Check out these photos of this incredible find:
A special thanks to Jason for allowing us to use these photos and the description above. You can reach Jason at The Auto Livery (telephone 513-738-1115).

Love them or hate them, there’s something about Harley-Davidson motorcycles that command attention, and during our recent visit to the Harley museum in Milwaukee, one of the exhibits that grabbed my attention was The Engine Wall. It had a magnificent display of Harley-Davidson engines including their big twins, their small twins, and other engines in the Harley family tree. I always found the evolution of the big twin engines mildly confusing, but this dramatic display cleared all that up. I grabbed a photo of each one and I thought I’d share them with you here on the blog.
F-Head (1911-1929)
The F-head engines were 61 cubic inches, and later, 74 cubic inches. These were Harley’s first v-twin engines, and they featured an inlet over exhaust valve configuration. What that means is that the intake valve was an overhead valve contained in the cylinder head (it moved down to let in the air-fuel mixture), and the exhaust valve was a side valve (or flathead valve) contained in the cylinder on one side (it moved up to allow the exhaust gases to escape). Inlet over exhaust internal combustion engine configurations (or F-heads) were fairly common in the early days of gasoline engines. If you draw the arrangement schematically, it sort of looks like an F (hence the name). The larger of the two Harley F-head models produced 11 horsepower.
V-Series Flathead (1930-1936)
The V-series flatheads were either 45 cubic inches or 74 cubic inches. They were sidevalve engines, which means the valves and their seats faced up and were located in the cylinders (not the cylinder heads), alongside piston (hence the sidevalve descriptor). This allowed the head to be basically flat (when viewed from the bottom), and that’s why these engines are called flatheads. It’s an old school design and it works well, but due to the twists and turns the intake and exhaust gases have to make and their poor heat dissipation, flatheads are limited in how much power they can produce. Harley would get around to fixing that in 1936 with the introduction of their overhead valve Knucklehead engine, but that would be down the road. Read on; we’ll get to that.
U-Series Flathead (1937-1948)
This was the second iteration of Harley’s sidevalve (or flathead) engines. There were two versions: The U and UL models (both had 74 cubic inches), and the UH and ULH (these had 80 cubic inches). The U series of engines were used for both motorcycles and Harley’s three-wheeled vehicles.
Knucklehead (1936-1947)
The Knucklehead was the first of Harley’s overhead valve engines, and the knucklehead name was derived from the valve covers’ appearance. Knuckleheads were made in a 61 cubic inch model and then in 1941, a 74 cubic inch configuration.
I’ve read that Knucklehead engines had serious oil leak issues caused by an overly complex rocker box cover (something Harley tried to correct with the next engine configuration, the Panhead). Knuckleheads had cast iron cylinder heads, which tended to make them run hot (cast iron does not dissipate heat very well). The Knucklehead motorcycles were the first Harleys that featured their distinctive Big Twin style, something that Harley has kept right up to present-day offerings.
Panhead (1948-1965)
The Panhead Harleys got their name from the valve covers’ appearance (they look like pans). This engine and the Evo engine (the engine that appeared two iterations later) are, in my opinion, the two best looking engines Harley ever made. In a major design shift for Harley, Panhead cylinder heads were made of aluminum, which improved heat dissipation and temperature control. The Panhead was intended to improve performance and address the oil leak issues associated with the Knucklehead. Did it work? I don’t know. I’ve never seen a Panhead Harley that did not leak. They sure are beautiful, though. The Panhead had a short production run, but it had a major impact on Harley styling.
The last year of the Panhead (1965) was the first year Harley had electric starting (that was when Harley introduced the Electra Glide name). My two ultimate dream bikes are the 1965 Harley Electra Glide and the Norton P-11 (which is discussed elsewhere on ExNotes). In my opinion, Panhead Harleys are exceptionally beautiful motorcycles.
Shovelhead (1966-1984)
1966 saw the introduction of another Harley engine, and yet another name based on the rocker box appearance.
I had a Shovelhead (a 1979 Electra Glide Classic). It was so bad I called it the Optical Illusion (because it looked like a motorcycle). My shovelhead Electra Glide was the worst motor vehicle of any type I ever owned (car, motorcycle, lawn mower, and Cox-.049-model airplane). It was constantly plagued by oil leaks and breakdown. It wouldn’t go a hundred miles without something breaking. After coming off a Triumph Bonneville, the Harley handled like a garbage truck. It would hang an exhaust valve every 4,000 miles, and as it was explained to me by the dealer, it was because when unleaded gasoline was introduced in the US, the valves would stick in the valve guides without the added lubricity provided by leaded gas. I don’t know if that was the reason or not, but in 12,000 miles, that bike needed three valve jobs (the first two were on the dealer with the bike’s 12,000-mile warranty; the third was on me because the bike had just over 12,000 miles. After paying for that last valve job, I sold my Electra Glide and I swore I’d never buy another Harley (but I did; see below). It was beautiful, though, and I wish I had kept it.
Evolution (1984-1999)
Harley got their act together on this one, and it was probably because they subcontracted the engineering to Porsche. Willie G drove a Porsche, and he knew they knew how to engineer engines. It was a good move. I had a ’92 Heritage Softail and it was a great motorcycle. My dealer? Not so much, but I guess it was all part of the Harley experience. I put a lot of fun miles on my ’92 including trips all over the US Southwest and Mexico, and I enjoyed riding it. The engine style was great, too.
In my opinion, the Evo engine was one of the two best-looking motors Harley ever made (the other was the Panhead; see above).
Twin Cam (1999-2017)
The thing most amazing to me about the Twin Cam engine was that Harley kept it as long as they did. It was basically a bust. Plagued by mechanical failures and overheating from the get-go, one had to be either ignorant or a masochist to buy a Harley with a Twin Cam motor. Cam failures, lubrication failures, and overheating were a fact of life if you owned one of these. The rear cylinder overheating issue was so bad that Harley incorporated a switch and an automated feature to shut down the rear cylinder if the engine got too hot. Amazingly and amusingly (at least to anyone with any mechanical smarts), Harley called activation of the rear cylinder shutdown feature their “parade mode,” with the implication that it was intended to accommodate riders who rode in, you know, parades. There were kits available to shield the riders’ legs from the intense heat the rear cylinder generated.
Twin Cam Rushmore (2014-2016)
This is a higher performance version of the Twin Cam engine that involved many changes, the most significant of which was liquid cooling for the cylinder heads on the Ultra Limited, CVO Limited, and Tri-Glide models (the models in which the radiators could be hidden; you can’t have a Big Twin Harley looking like a Gold Wing, I guess).
Milwaukee Eight (2017 to Present)
Harley joined much of the rest of the world in 2017 when they incorporated four valves (two intake, two exhaust) for each cylinder. Let’s see…two cylinders, four valves per cylinder…that makes eight, and Harley’s hometown is Milwaukee. Hey, the Milwaukee Eight! (At least the name makes more sense than the Rushmore mentioned above.) These engines had problems and Harley had recalls to address them. Wet sumping was a major issue, as was overheating. The Milwaukee Eight incorporated a plastic intake manifold, too, which also had issues. I like the name, though.
I thought the Harley Museum’s Engine Wall was very, very well done. Harley put a lot of thought and work into it, and as a mechanical engineer and former Harley owner, I enjoyed it. There’s the obvious: the actual engines on display. And then there’s the subtle: the slight tilt of that orange wall toward the visitors so that the engines were presented not an angle, but straight on as you tilt your head up to view the different engines. The colors are classic Harley: black, orange, and chrome. It’s one of the better displays I’ve seen of any type in any museum. The whole thing just works. Harley got The Engine Wall right; they did an awesome job.
As mentioned at the start of this blog, there were more engines on The Engine Wall. These included their smaller engines (for the Sportsters and the racebikes), their singles, and some interesting other twins. Keep an eye on ExNotes; we’ll show those, too.
