I have a 1997 Arctic cat cougar 550 just re-built hole top end. Sled is idleing at 1000 rpm and hitting 3000-3500 rpm when clutch engages. This is normal right? Please let me know any help would be great. Thank's

My 95' Cougar idles at 2-3000 and engauges at the touch of the throttle. My 97' Zl 440 idles at 1500 and engauges at 4500. I think yours is fine at that.

Idle should be 1500 to 1800 rpm.

Yeah idle and engagement might be a bit low, not to worry it may idle a bit higher as it breaks in! You did add a bit of extra oil to the gas? You have cleaned the carbs?

northmainer

Yes I did put a little mixed gas so it did not run dry on first start, and yes carbs have been cleaned.

Could it be having idle problems do to the silencer boots being off (from air box to the carb). I didn't run it in the snow with them off just on a stand.

The air box will actually make it run a bit richer.
