I just bought a 2006 trx450 with stage two hot cams and full exhaust. It is electric start and does not start unless you push start it then it runs great but does not idle when you let go of throttle. Please help I have a race this weekend!

Get the valves adjusted and perhaps reset the idle - usually when they get hard to start the valves need to be set to proper clearance
Sounds to me to be a Throttle Position Sensor is going bad. Try unplugging the TP Sensor then see if it starts & idles. The Plug for the TP Sensor is connectected to the Carburetor with 3 wires.
