I have been to three dealers non can solve my problem.
When the sled is cold it runs perfectl, wide open with no power loss. After putting on a few miles and the sled warms up to full temp, if I squeeze the throttle past 4200 rpm the mag side of the engine floods out. Once it floods itself it will not clear itself unless a dry plug is put in that side, I can stop and switch the plugs from side to side and the machine will run fine again untill I go past the 4200 rpm range. We have tied all the usual things to diagnose, like replaceing plug wires & caps, reversing plug wires to the plugs, have checked all electrical resistances to servo, injectors, cpu, ect. have even had it on the cat analyser and it comes up with no error codes, has anyone else had this problem and if so what was the fix.

It sounds like the high speed coil in the Stator is going bad. It can be checked with a ohm meter. The shop manual should have the values. It should be checked cold and warm.
