My 09 polaris dragon 800 keeps going into limp mode. What it will do is the cel light will come on around 6800-7000 rpm. It will come on a couple of times then go into limp mode. I have tried messing with the ethanol wires but didn't make a difference. I always run shell 91 fuel with no ethanol. What would happen if I have the wires plugged in and running ethanol free fuel. This would theoretically stop the sled from going into limp mode? The limp mode is caused from it running to lean? Or could there be something wrong with detonation sensor? I'm not suRe wat to do next. Thanks for any help in advance!!
