great video man. I have the exact same bike as this and I had it locked up on me aswell, the problem with mine was my timing chain was old and stiff and it siezed my intake cam, I took it apart slightly sanded the seatings for the cam and redone the valve clearances and replaced the timing chain and she was mint, to check the oil on those bikes theres a dip stick on the headstock opposite side to the vin number as they have oil pumping through the frame.

And 4 strokes tend to last a little longer and are better on fuel, more comfortable to ride. 2 strokes are just made to be on the top end all the time, and they drink gas a like crazy, the premix itself cost more than the gasoline

Has 290 big bore kit bored to 312 high compression piston stroker crank. Any idea on how to keep it from leaking? Had to tear the motor apart due to clutch basket exploding.

@kurtg3891 Жыл бұрын

you must have done a few of theses because you were fearless when it came time to split the engine case ? since there was oil and the oil pump seemed to be functioning properly what is it that you think caused this issue with the crank bearing to have burned out ? i might presume it possible they had only re added oil after it already failed because this seems like something that should really never happen if you always maintain a bike properly ??
