I have to bore out my cylinders and I'm having trouble figuring out what the STD size is for the cylinders! My current piston tops show 6 82
Its odd because they typical go 6 25 or 6 50 or 6 75 if there Over sized by .25 .50 .75
I want to go .50 OS BUT idk if they're already .82 OS but that makes no sense to me and to get a custom made piston and rings would be way to much for this lil bike so i doubt anyone did that.
Any help mates?
