    I have heard much about the kx65 exhaust. Crmachine even sells the adaptors to make install easier and it is close to the 66- 67 displacement on these "80" cc engines. On the other hand I recently have heard about the yz85 being a better match. The guys at jnmotors swear by the yz pipe and say that have dyno'd the kx, ktm, cr and the yz and the yz is best of all. All are expensive and I will have to choose. My choice is between the kx65 and the yz85. Does anyone have any personal experience with either of these two exhausts?

    No matter what you still need your motor to be tuned to it. we get good results with no mufflers .it all way pays to get the best if you do.
