Have a problem and seeing if anyone else has had issues. Have a 2013 XC. Bike started having a problem where it will randomly start idling and bouncing back and forth upwards of 400RPMs difference. Driving with constant throttle, the same thing happens but with less of an effect: continual jerking as it goes up and down a few hundred RPMs. Yesterday the first corner I pulled up to it stalled when I put in the throttle.
Throttle position sensor? Asked the dealer, said could be a vacuum leak somewhere too. I'm afraid that it might not be covered under warranty either way, and I'm having them check into it before I bring it in.
