Shee won't start

[..xXBansheeXx..]

I am racing MX on my shee and Saturday 3 times the thing died on me on the track during the first Moto. The second Moto it ran fine. Then Sunday I started it and it ran just like it normally does when I start it cold it took it a second to warm up and then as I was trying to rev it, it would not rev very high and then it died. Won't start now. Any ideas? I pulled the K&N 2 into 1 air filter off and tried again. I pulled the plugs and dried them off and tried again. Still not starting. WTF?

I would start with a compression test. Good indicator of mechanical condition of motor. If good then get into wacky ignition/carb problems

I agree with the compression test. My shee wouldn't start and had no fire, so I unplugged the T.O.R.S. and got the spark back butit still wouldn't start. Compression turned out to be 85-90 cold, so it's about 90-95 hot. Good luck........
