Went to the track today. The bike was a little more finicky than normal getting started but once I get it going it ran great. Rode it for about an hour and then went to the truck to take a brake. Let it sit for 20 minutes and then went to start it and nothing. I got it home and pulled it apart and it doesn't seem like I have spark. I'm testing by kicking it over and holding the spark plug to the head, I also tried the holding it to the head bolts. That's correct way to test, right? I disconnected the kill switch and still get no spark. What else should I be checking?
