This may have been done on purpose . I don't go by the factory markings either .
But in this case ?.. unlikely ..

I'll bite...

Why would you want to change the timing of the cam in relation to the crank? Or am a missing something (as usual).

Some performance cams, installed with other performance mods that are tuned together, require significant timing advance from the stock manufacturer settings.

If that was me I would have just ground down the shaft to make the cover fit.

With all the cobbled stuff I've already found, I'm surprised the guy who made this mess didn't think of that. Maybe a tube of RTV was cheaper than buying a grinder?

Gday Stu, yep looks better and thats a sleeve we're looking at? That thread could do with a good rub with a wire brush aswell.
You having to dismantle the motor because of the previous owners efforts gives good reason to why golf was invented, he should've taken that up instead!!

Right, a Speedi Sleeve. $34. And it's only 1/4" wide, so I had to drive it on a bit at a time and test fit the cover to see if the seal was riding on it.

That was before teardown. It's all good now.

Couldn't agree more, Foxy. A friend in California just had his Commando "restored" by someone else here in Phoenix, but they didn't touch the motor, except to clean it up. I asked him why would he pay a fortune to have someone basically paint and polish and fix external and cosmetic stuff, but trust the motor. He said the PO told him the motor had "recently been rebuilt". Besides, he went way over budget as it was. I hope he doesn't live to regret that decision.

I don't think so. The wristpins were a real sloppy fit, so I had Short Block Charlie's in Phoenix bush these rods with bronze bushings. They're a .004" interference fit mounted with Loctite stud & bushing mount. Bushing/pin clearance is .001".

I bought adjustable cam sprocket off ebay 7 years ago, so they are out there to dial our cams. I've done cam degrees on V8 on dyno and .5 degree can squeeze out a few good percentage points of power or extra sweetness across the range.

Well, I'm about 90 days into this job, and it's turned out to be a frame-up restoration, or at least a refurbish. The bike came down to the last nut and bolt and is going together nicely. I'm still finding buggered and missing parts as I go, so it's been slowed by waiting on parts. Here's my progress so far.
