I have read a ton on this forum and many other sites on the kick back issues. I have an 86 R with a 295 top end. Bought it a year ago from AZ supposed to have been ready to go. Had a broke skirt on piston so it's sat until now. I'm on the 3rd cdi and no change. OEM, Rick's and dynatek. New engine top to bottom also. Just rebuilt entire thing. Checked connections, checked copper in the harness in multiple places also. New keihin carb, coil and stator checks out ok per manual specs. From what I've read it's leaning towards the cdi. Opinions greatly appreciated. Also if anyone has an OEM cdi for sale let me now in pm please. Would like to try another one just to satisfy myself. Thanks for your time and feedback.
