Hey guys,

Last weekend I was out in mcbride on my 2019 mountain Cat with about 1300 miles. I had an issue pop up where my sled would idle fine and would be okay up to about 4500 rpm but then if I tried to go past that it would bog right down and hardly move. I was trying to limp it back from spirit and I found the best way to get half a** power was to really blip the throttle quite aggressively. After fighting it for a bit it almost felt like it broke though and went back to being totally normal. No issues after that.

At first I thought the throttle was iced up and it was a tps sensor issue but cleared that up and moved freely and the issue continued for a while so not certain that was the fix.

Has anyone had this happen before or have any idea what it could have been? I was thinking possibly bad fuel or something. Just want to see if there is something I can investigate before next trip as I’d hate for it to pop up again.

Thanks All.

That's an odd one. It kind of sounds like bad reeds but that wouldn't fix itself. The exhaust valve cables can go bad and/or out of adjustment. I like to pop them out of the servo and pull each by hand to see that they move clean and snap back closed. If movement is ok then adjust to spec. One of mine even broke the return spring under the cap up at the valve.

It's the throttle safety switch yes


Open up the left side panel and above the coolant tank, unlug the grey connector if it does it again

I left mine unplugged, just make sure you use the teather
