Complete engine tear down and install quality bearings through out.

I thank him again for sharing this info with us.

Also, run a quality pre-mix oil at the ratio suggested by the oil manufacturer, or 32-1 if none is suggested.

I think installing a smaller rear sprocket would help also. It would run the engine at lower RPM, given the same speed.

Yes about the bearings and the sprocket.
I been running a 40T which put my motor in much higher rpm band.
Nice bottom end power but now afte approx 800 miles it's toast.

I never had any issues running a 36T

I did go to 30 for a wile but it seems to small.

The engine don't pull it real well until you get going.

Im going to start another thread about the broken engine.
