I was wondering how harmful it would be to shave the end of a piston ring with a file? When recenlty installing the cylinder on my yz450f, I accidentally snagged the tip of a piston ring. This caused it to bend down slightly. I top end back on bt have not yet ran the bike... I want to ride this weekend and was wondering if i could pull the top end and just shave the end of the ring to take the sharpness/ jagged edge off of it.. I dont minf replacing the rings, but wont be able to get a set in before this weekend... Any thought? I know i shouldnt do it, but is it that big i a deal?
