Hi! I bought a Yamaha Tri-Moto 1982 YT125J, in good condition except, it's smoking white really bad, it start (on first stroke) but doesn't run idle and it has no power any ideas? Here's what I try so far : -Clean the carburetor; (On of the jet was blocked I manage to clean it but... no improvement ) -New Head gasket; (There was some oil between the cylinder and the head, so I suspect it was leaking... no improvement) -Clean the muffler; (it was full of oil and almost block by a kind of charcoal... easier to start now but still lots of white smoke ) -Try mixed gas; (The pump still work but I suspected that it was giving too mush oil, so I try to bypass the pump... still no improvement) I seen post concerning the crank gasket... any idea or advice... Thanks! PS here's some pics!
