Hi guys
building up a 1980 dohc cb750 motor with +1mm ie 63mm pistons and have twisted a piston ring
it still goes in the piston groove ok but is a bit tight for my liking so ideally need a replacement
it is the middle ring that i need, or a single piston set.
i believe this is the 425 type of ring, measures 1.15 mm thickness stamped 1.00 for the +1mm
anyone have something or can point me to a supplier?
thanks
