Loss of Power in 2017 Polaris 800 Rush XCR

The correct fuel setting makes all the difference
2017 800 Polaris Rush XCR snowmobile
There are two different fuel settings on the Rush XCR gauge: ethanol and non-ethanol. Be sure the correct one is selected.
Q: I have a brand new 2017 Polaris 800 Rush XCR that seems down on power. At first I thought the engine just might need some break-in time, but after 600+ miles, my top end speed and rpms seem down. I should be able to get more than 88 mph out of this machine. I’ve owned several other versions of their 800 H.O. engine, and those sleds were absolute rippers! Am I missing something? – sticksandstones247

A: The answer may lie in your dash display. It’s highly unlikely you’d have a mechanical failure in just 600 miles, and you didn’t mention anything of that nature, so we’ll assume the rest of the engine performance is OK. Double-check that you have the correct fuel setting on your display. If that setting is incorrect (i.e., using non-ethanol fuel when the sled is on the “ethanol fuel” setting, or vice versa), then you will experience a slight loss of power. – Experts
