I need to identify the piston size in my 2F engine. There is a number .75mm stamped at the rear of each piston. Is this a oversize? and how much more can I bore if it is?
My head gasket blew between cylinder 3 and 4. When I pulled the head I found a scored cylinder in #4 hole, it looks like a wrist pin clip or the wrist pin itself got into it pretty good. I haven't measured the depth yet but need to know how far I can go to clean it up.
