I have a 1999 Arctic Cat 250 2 x4 ATV and when a start using it, it idles fine for a while then after it starts warming up, it starts to idle faster and faster. is this a intake gasket issue maybe? And if so can anybody explain the repair briefly as I believe I can do it if its not too complicated. Thankyou.

 

it is possible. try lightly spraying some carb spray around the intake and gasket area. listen for idle speed changes. check bolt tightness too.

 

Ok thanks. Any other ideas in case that doesn't change idle speed. should I do that when I first start it or wait until idle starts to increase.

 

wait until it acts up. did the problem just start overnight? been slowly acting up? did anything happen to make this problem (backfire/running rough)?
