Pieces of steel in cylinder??

The shop is going forward with just a cylinder hone. One thing I'm concerned about is the crank, and how undersized the journals are already. He suggested grinding and polishing, but if I can't find bearings larger than .040", I might be up a creek without a paddle.

Crank bearings can be had all the way to .060. A lot of people will scream about it, but stack .060 up on a feeler gauge. It ain't "THAT MUCH". Especially on what will be a mild build like yours. I'd do it in a minute.

BUT.......all THAT said, since you HAVE a crank, what I would do in THAT case is just get a crank kit. It will be ready to go with bearings and all and probably be about the same cost as turning the one you have.
