Just got a 2009 summit 800r from Colorado. I'm riding it in michigan now. Having a high idle issue. Have to use the choke to get it down from around 3500 rpms. Carbs rebuild. .20 jets. New floats. New jugs, pistons, and head. New crank seal on clutch side. Motor is fine just can't figure out the idle. Carb boots are mint. All new gaskets. My question is does this sled have a computer that the dealer has to retune for sea level elevation?? I'm lost I've done everything you guys told me and no change what so ever. Any help would be appreciated!! And I adjuster the air fuel screws it did absolutely nothing. And now as we speak I'm getting my carb slides chromed so maybe that will fix it.
