I have a 99 YZ400f that is a street legal sumo. I have exactly 7.2 miles on the street on the bike. I installed a moose stator and got to ride the bike 7.2 miles before it died. So I called moose and they sent me a new stator no questions asked. After installing the new stator I still have no spark at all. I have tested everything on the bike but the cdi, I don't really have a way to test it. does anyone on here know how to check or test a cdi on this bike? Or am I to just start buying parts I.E. a new stator, and testing them on the bike. I guess I am on the lookout for a stator for now.
