My bike's idle rps are at 2000-3500, sometimes though it idlles at normal, about 1000rps, , it about 50/50 chances. I have changed the intake manafold seals, but did not help. Would it be the throttle position sensor, I have no worning light on the dashboard. If I repleace it, how do I reset the system.

 

What due you have? is it a fuel injected M & M bike? if it is check the engine temp. sensor.

 

YEp, repleacing engine temperature sensor, took care of the high idle problem. Thank you for the suggestion.
