I've got a 2010 can am 650 xtp with hmf penland slip on exhaust k&n air filter snorkals and Dalton clutch kit it has a high idle. It idles at 2200 rpm if I put my hand over intake and then.uncover it it will idle down to about 1600 rpm but right as I hit the throttle again it.will idle at 2200 not.sure what the problem is or.how I can fix it
