I have a 125 BBR Pit bike
it has a RCM engine
Im looking for ring and head gasket kit
the cylinder syas 124CM3 / CONGYM on it
where can I get these rings and gaskets
not a brand i know but they're mostly the same engine with different branding. The only way to be certain is to take off the head and measure the width of the piston, the piston deck(height between top of gudgeon hole to top of piston) and the gudgeon hole itself. If you dont already get yourself a set of vernier caliper(cheapos will do) to get accurate dimensions. Then just search ebay/the net for what you want, probably find its the same as lifan piston
