Wondering how to figure out if I go with the stock, or .5, .75 or 1 mm over bore?  cylinder is in good shape and does not need to be bored so do I have to take it to a machine shop to find out?
I found a post that said they would need the piston to bore the cylinder to that piston, and if that is the case what is the best size to get for least margin of error?
