make only one thread on a problem you have would be easier. give us more info on the bike if you can. is this something that just started? have you checked the oil in the trans? have you done a leakdown test on it?

What is the leakdown test????????

 

[Surfrjag]

jetting a 2stroke is crutial. too much of a lean condition will cause overheating and destroy a motor. by pressure testing the motor you plug the exhaust and pressurise the intake to about 6psi and see if air leaks out somewhere (intake manifold gasket, oil seal, base gasket, head gasket) you can find the leak by spraying soapy water on it. this leak will let in extra amts of air that cause the lean air fuel mix. also is your oil injection mix still hooked up? are you mixing 32:1?

could be a crank seal. what are you running in the bottom end fluid wise?
