Ernie, I am wondering if they did pressure test on the crank cases? You may have a air leak and it will do funny things too. Does your bike have a bleeder...
Ernie, If it ran fine before Iraq I would think it was the result of sitting and minor corrision in the advance mechanism. You \'ll have to pull the flywheel...

Ernie, I cant remember if the gasket is copper? If so you can re-use it. you need to anneal the copper. just set the oven to 500 deg and put it in the oven...
Ernie, I also want to ask if you pulled the carb apart and cleaned it? sometimes if they sit for a while with old gas and oil in them they will gum up. I ...
Brian: Absolutely. I not only rebuilt my old carb but within the last couple of days replaced it with a brand new Mikuni VM36 from ProFlo with the exact ...

All: Thanks for all your comments regarding my "pinging" engine. I thought I had tracked the noise down to a worn steel "brake disc" in my starter assembly ...
Ernie, mine makes the same noise. The clearance between the piston and cylinder maybe on the high end of the specs. If I remember the max spec is .008 and mine...

Brian and Dave: I'm running 93 octane. This really has me stumped. The ping is actually more like a knock. When I decelerate at closed throttle, once the...
Greetings guys, This one caught my attention. Sounds like large piston to cylinder clearance, bad wrist pin or even possibly a broken ring. The noise becoming...
