[Carl Keeton]

Ii Keep burning up my rings badly. Anyone got any help? I got a stock pipe, no silencer, new carb, I’m on my 3rd piston and ring in a year. I do break it in before riding. I learned my lesson there. But I need some help.

You have to take the piston out and look at the underside of the crown. If the oil has burned black there then your jetting is too lean which makes the engine too hot which wears everything down faster. The excess heat on the cylinder wall causes the oil to evaporate off. dragonfly75.com/moto/plug.html
