Idle Issues

[Nug]

I have got an 02 Summit 800 Himark X that is stock and it has been running great this season until yesterday. I took it out for a ride and it would never idle down. Any time I would stop it would sit there and idle at about 2800 RPM's. If I would hold the brake and rev it up then my idle would drop down to where it should. It was too cold out yesterday to mess with it so I was just gonna check for some ideas before I started to look it over thanks.

I have the same thing going on with my 01 700HM when I stop it idle's at 2500 or so for about 20 sec. then drops to normal so could someone kill to birds with 1 stone here thanks

check the carb boots for cracks, you probably have an air leak somewhere

yes check carb boots my sled has a weird idle and i found the cracks in both of my boots on the top of them right before the boots meet the cylinders if i remember right.
