I have a 74 CR250M and I read that the cylinders can NOT be resleeved! Is this so? How many times can the original cylinder be bored? Are there any other options short of a new cylinder?
Thanks

Not sure if you can re-sleeve or not,but Honda sells 4 OS pistons .25-1.00...So I guess you could re-bore 4X. eL

wiseco still offers oversizes up to 080 which is well over the range honda offers.
