This should be an easy one for you.
When my CA77 is running it sounds great no unusual noises.
But when I switch it off just as is stops there is a clonk as if something is dropping inside the motor. Its not loud and it dosnt do it very time. I have herd the same noise on other Honda engines I had a 600 silverwing with the same noise.
Is it anything to do with the starter clutch.

It's the hamsters plopping down on the bench!! I jest. Offhand guess, crank might be finishing running through a rotation (360 crank?) and the compression from the power cylinder is forcing it down. LM will have a better answer I'm sure. I'm just guessing from my attempts of timing before realizing no plugs makes it easier to do.
