Hey everyone, Here is another tip for what it's worth. A quick way to see if your bike is too lean is take it up to full throttle, not for a long time in case it is, but just wind it out, then completeley let the gas off and let it decelerate. If the motor goes dang da dang dang da dang as it lowers RPM than you better check the jetting before it burns up. It should come off of top end sounding nice and smooth not like it's detonating. Another thing, when your out ridding hard and fast for a few miles and go to ease off the throttle, DON'T! either stay 100% wide open or roll off all together. When your running it hot like that and you barkley let off it leans out the mixture in the motor and is a lot more prone to sieze then if you just let off all the way.
