Hello I have a 99' MXZ Ski Doo 500 and I have tried everything to try and cure my top end problem. I cleaned my carbs, my power valves, changed the ignition coil and spark plugs. It revs up fine with track off the ground. It will not open up to full revs, it goes to 6500 rpm and touches 7000 briefly and is intermittent. When it is revved that high it seems like one side stops sparking. Please help me I am lost! Thanks
