Nobody buys Harleys for the handling and plenty of chopper frames with modest gussets survive just fine. I peeled the gussets off an Evo Sporty frame to harvest the neck tube and it's not hard work,...

4L80E is a nice upgrade. (The 60 didn't have to suck but execution including those stupid plastic pistons and weak clutches was moronic.)

Shelby likely used a C6 since they're difficult to kill.

The Triumph doesn't care how heavy you are. If you find a stock frame a bit cramped then a mild stretch solves that easily, say 2" on the downtubes and backbone or more if ya like, and say 14"...

The TC top end offers more cubes and top ends are quite plentiful for small change while the early TC bottom end has those shitty chain adjuster shoes still failing and killing engines because most...

Shipping to the UK might be expensive but OTOH it's common for buyers to import US machines. Ensure any documentation like title is correct by UK standards.

What DTIA said, it was common in ancient times (good for ease of duplication) and the rust shows it sat unloved for a while.

The look is VERY easy to duplicate. The lack of cheap HDs overseas...

Note to anyone who ends up with blasted seal areas (not to be confused with going deep into the slider and tearing up the sliding surface where the bushing attached to the fork tube itself runs but...

It takes about a minute to make a bogus Facebook account and you can use a throwaway email (everyone should have at least one spamdump address). I would never have one under my real name either.

Cool Abarth in the background too!

What rotor OD did you use? The larger later rotors are easy to bore for the larger early hub pilots.

Promptly download the factory service manuals and parts catalogs for everything you ride then use their default lube recommendations if in doubt. The Donnie Petersen Ironhead book is outstanding (and...

If you're gonna face valves on a lathe the valve needs to rotate with respect to the grinder and the lathe isn't fast enough to turn a grindstone, but they're not complex. If your grinder attaches to...

Contact S&S with the case numbers and they should be able to give you the info and point you to the engine manual download.

I think I wouldn't bother unless a dearly wanted to use valve facing as a benchmark for lathe modification which would be absurd vs. turning test bars.

If I did valves in great volume I'd find an...

Unless you specifically require a large air compressor to run a blaster or other tool or paint gun that REQUIRES pneumatic power you don't need a large one, just enough to run a pneumatic blowgun,...

Those Bendix and Zenith clones work well enough on a stock engine so I'd be in no hurry to throw money at that bike until the Pan is finished. Any properly tuned common carb is ample for a stock...

Truck rentals are an option many forget and some chain stores rent trucks with liftgates. (I installed a cheap used liftgate on one of my half-ton Fords after installing overload springs and it's...

^^^This. I've been extracting broken shit from all sorts of machinery for decades and mostly use screw extractors for soft hollow parts like broken pipe nipples and fittings. I use machinist's...

Don't omit a valve job since you have the heads off. Old air-cooled motorcycle engine designs wear quickly and off-season top end jobs were a major source of shop revenue in those ancient times. I...

People also perform home orchidectomies...

An impact gun (specialty items with calibrated, adjustable clutches excepted) is not a torque wrench or precision tool. Motorcycles are delicate...

If the engine's intact I'd bring my jump pack and compression tester (I test every used bike I buy) and check out the five speed. I'd pull the plugs, inspect them, toss a USB borescope down the plug...

Slay it and do whatever you like. It's not valuable so why not have some fun? They make nice bar bikes.

Just build whatever you like. The museums have enough originals (which if you ride them wear out and require restoration after which they cease to be original).

Ironheads aren't Panheads, they're...
