I recently replaced the crankshaft seals as well as pistons and rings from cruzinimage. Rode the bike gently, no revving cold, under the rpm red zone for about 500miles with no issues.
Suddendly I lost power at the right cylinder and idlle back home, to scratch my head between carburetors and timing to trouble shoot the bike...to finally remove the top end and finding a torned up piston...
anyone experience a similar failure,please check the picture !
