Have other posts about problems I’ve had getting my Griz running . After all the things I’ve done to get spark I replaced a stator that OHMd ok with a new stator with pickup coil and it started but backfired and ran terrible ! I replaced the cdi (capacitor swelled) with a used cdi and it burnt it up capacitor swollen ! I took wire harness off and checked it for bare wires and it was good ! Is it possible and would it burn the cdi if the new stator I installed (it started with this stator) was putting out too much AC voltage ? Did a top end rebuild also but engine was really ok !
