Hey guys new to the forum but I just got a 2004 yfz a few weeks ago. I’m having some issues first issue is my key works backwards I can turn it over with the key in the off position? Second issue is while turning it over I get one spark and that’s it but if I move the kill switch on and off it’ll spark one or two times until I do it again. I have replaced the harness the old was all hacked up. I’ve put a new key switch on it and all have tried different cdi box’s, rectifier, coil and have put a new kill switch on. Any help will be greatly appreciated!
