I might give it a good look in the future, if I feel it is worrth the effort.
The crank and bearing fit was ok actually (I found something like lapping compound inside the hollow crankpin however, and 1 small piece of aluminium swarf stuck to the bottom of the sleeve). The crankpin isn't pressed in, it is machined in one piece with the crank, and then hardened (and precision ground I hope).
After a few tanks on the stand the piston crown looks perfect, as is the fit. I'm quite amazed by the piston fit in fact...

If it doesn't shake itself to pieces during the first half gallon or so, I will probably start grinding away.


CP, how do you make head and liner shims? I have experimented with hand cutting them from various materials...but it is a tedious job. I usually try to find a shim that fits as good as possible from another engine, and modify that if necessary.
