Hello All, This is my first post here, hopefully of many, because I have absolutely no clue what's wrong with my bike. It's got no spark. I checked the ignition coils, spark plugs, and all the switches are working fine. It initially died when I was riding down the road. I wasn't doing anything special, I was at about 5000RPM and it just suddenly cut out, like as though I had hit the kill switch. I couldn't get it restarted and haven't been able to get it started again. Ignition coils are good, step up coil is good, I don't know what else to check. Anyone have any ideas?
