Found this forum while trying to figure out why my YammaGamma is smoking. Well that seems to be fixed but it wouldnt start this morning and dripped a little fuel. Will look at that tonite. Done 400km since getting it together and passing French moto test(arrrg). Its a rocket ship above 7k usually starts 3rd kick cold. 86YPVS from Italy cheap. A bit loud with those Figaroli pipes and Stan's stage 2. Its been like a video game getting this far, get stuck, look online(cheats) fix the problem, next!!!
And some of the problems delt with so far:
-wouldnt idle: carb slides were in backwards(duh)
-Clutch wouldnt disengage: removed and freed plates
-Exhaust spitting oil at flange: put in viton seals
-Clutch slipping at 7k+: New plates + 3 springs + box oil
-Excesive smoke: adjusted oil pump
