b40rt Posted August 29, 2015 Report Share Posted August 29, 2015 Is the coil earthed properly ? Quote Link to comment Share on other sites More sharing options...
tylermerrill Posted August 29, 2015 Author Report Share Posted August 29, 2015 not quite under standing what u mean I've tried grounding the coil too the frame and nothing i unhooked the kill switch thinking that was the problem 1. tried 3 coils and nothing 2. new plug 3. new coil 4 i tool magnets out to the magneto and they looked good they were not broken also looked at the condenser look fine could my condenser not be putting enough power to spark the plug off the coil and would it just show that i have power from the magneto but not enough to ignite the plug thanks Quote Link to comment Share on other sites More sharing options...

biffsgasgas Posted August 30, 2015 Report Share Posted August 30, 2015 Yea you have to solder them in place. You can use eBay or one of those old school love free or die New Hampshire bike places. Not the big chain joints. Bike bandit I believe has em too. --Biff Quote Link to comment Share on other sites More sharing options...
