No Sparkplugs are Sparking
I ran my first track day this weekend at Blackhawk Farms Raceway in South Beloit, Illinois, and I had an electrical issue which cut my weekend short.
As I came out of the last corner onto the front stretch, I opened up the throttle and power-shifted into second gear at redline. I accidentally hit neutral instead of second and bounced the rev limited a couple times. I let off, engaged into second gear, and rolled back on hard. The instant I roll back on, the bike shuts off completely. I coast to a stop. The starter turns over, but the bike won't start.
I take the key out and put it back in: won't start. Took the battery out and let it sit for half hour: won't start. Checked the compression (which was fine): Still won't start. Test the sparkplugs, and determine that none of them are sparking. I bypass the kickstand kill switch: it still won't fire. Remove the tilt sensor and shake it: it still won't fire. I put the whole thing back together and load it up on the truck to head home. As I'm loading it up, I hit the starter one last time and she starts up! The sessions are over for the day, so I camp out and plan to hit the track the next day.
First session of the second day, the bike completely shuts off again on the first lap, but closer to 13k (as opposed to 15k) RPMs. Again I tear it apart and can't find any cause. Put it all back together and it magically starts.
I pull back out on the track, and I don't let the RPM get above 10k. Again on the first lap, she stalls. I coast back around to the pit, hit the starter, and she starts up for about 1 second and dies. It's been 12 hours, and she still won't start. I haven't torn back into it yet, but I'm at a loss for possible issues.
Also, this happened once to me on the street last fall about 5000 miles ago, and she started back up after about 5 minutes of just sitting.
FYI: 2006 CBR600RR with 18000 miles (all by me). No stunting; first track day ever. I was running with OEM plastics, and disconnected turn signals, headlights, and taillights.
Electrical issue? Grounding issue? Bad killswitch on the grip? Back kickstand killswitch? Bad tilt sensor killswitch? Bad ECU?
What would lead to none of the sparkplugs sparking? Any help would be greatly appreciated.
