Description : I replaced the piston 50 Mustang piston rings and now the head is overheating terribly. I just drive for 2 minutes and it's overheated that I'm smoking and the bike can't start. After cooling, it ... and rides again for 2 minutes before overheating. He's been doing it since I put new piston rings.
Last Answer : How much have you driven since the exchange? And - you just changed the rings - or the whole set (+ cut)? Anyway - now you are running the engine, so you should lubricate more (approx. 1:20), do ... anti-knock gap, the tightness of the cylinder head ... And don't forget to clean the exhaust. ;-)
