How do you test if the pulse generator and the CDI are both working properly? My 97 XR600 is bogging pretty bad when I blip the throttle off idle and it dies after high speeds. It also bogs and dies in first gear when I get on it. I've tried all different kinds of jets and setups, but so far nothing has worked. I've checked the valve clearance and I've checked to see if there were any air leaks, but everthing seemed to be fine. The compression is a little low at 130psi, but the bike starts right up. Any suggestions?
