I have a 1989 RM80 that is running rich on the low and high end. I know the low end throttle response can be corrected with a new pilot jet, but on my high end I'm not sure. My fuel mixture at the moment is 36:1 and I have a 220 main. I know for a fact that it is exceptionaly rich on the high end, but should I change my my fuel mixture or my jet. When I am riding it at full throttle it will have the clean crisp engine noise, but then it will make a bogging down noise and the RPM's will drop. Then sometimes it goes back to the crisp sound again. I dont know if I should change my fuel mixture or main jet.
