    Dropped a bolt on the engine

    So my 81 started to sound like a diesel, I suspected something with the valves. I found the b cam chain tensioner broken. While reassembling I dropped one of the cam sprocket bolts into the engine. I can't seem to find it. I've spent hours with a borescope, magnets you name it from both the top...

    81 CB750 First Startup

    Just thought I'd share my success. I'm building a bike from basket cases. The engine, carbs, everything completely rebuilt. She fired right up. I have some tuning to do and a lot more work to finish her off, but I'm way ahead of schedule for being able to ride it next summer.

    Valves clearence too tight

    I'm rebuilding a basket case engine, 81 cb750k. The valves were not labeled or numbered. So I just cleaned everything and gave them a lapping. I'm at the point where I'm setting the valve clearences, yes I know, .005. So, I couldn't get a .0015 in with a the smallest shim I have, 2.75. So I...
