wiseco piston

[tman]

does wiseco stamp the piston part # on top of the actual piston? Just tring to find my piston overbore for 86R. I was told it had a wiseco .040

best way to find out what size piston to order is to measure the bore and make sure the oversize you need will work. sometimes going by piston size works but sometimes it doesnt depending on the wear on the cyl wall.

Thanks beerock

I check today and wiseco does stamp their part #'s on top of their pistons.

I recommend measuring with a pair of calipers just to be on the safe side.
