Might want to verify Fuel Pressure a Gage can be rented @ Auto Parts Stores (RZR takes same adapter asMany GM Cars) I assume you have inspected the Air Filter & Intake Ducts

I just took my 570 sportsman in with the same problem and it was the fuel pump. Seems to be a problem with a lot of Polaris fuel pumps as the service manager told me that different types of gas seem to eat up some of the plastic parts. Mine was covered by warranty.

 

Update....
There is a recall on some rzr's for a cover that snaps over the fuel pump to protect it. Well upon smelling gas and inspecting mine, I found the top of the fuel pump to be cracked. I ordered a new pump assy, $330, and installed it. I took the rzr in for the recall and upon getting it back found the issue of it cutting out on me. I saved the old fuel pump as the pump itself was not bad, so I swapped just the pump ends. Low and behold the rzr is back to running perfect.

 

Mine did the same thing. Check the brakes. My master cylinder stuck and cause a slight brake stick and it will go into limp mode if it detects brake and gas on at the same time. Sometimes they throw a code other times it won't. Easy way to check is make sure your brake lights are operating normally.

 

HUHHHHHHHHHH!!!!!!!!!

 

When throttle and brake are applied simultaneously for more than a few seconds it triggers a C. E. L, sometimes the light won't come on but when this happens it will go into limp mode until the throttle is released. I realized he already found his problem. But for future reference this is a common issue. I'm a tech at Polaris and we see this a lot.

 

Gotcha…..I have an EBS model and hardly ever touch the brakes so your reply was total French to me...lol

 

Gotcha. Ebs is a love hate relationship with me haha. But yeah we do see a lot of brake issues. Usually not with the 570 but I was unfortunate enough to have it happen to me. But anyway, glad everyone's fixed up. Ride safe

 

I think everyone that has ever owned a Polaris EBS car or atv has that same relationship. After many mess ups me and the ebs have now come to an agreement. I will keep it if it will quit trying to kill me. Really though when you finally learn what its going to do and what it wont its not very hard to control with gas and brake, and high range when descending steep and slippery terrain. If the ground is dry and not to gravelly, its the best thing since mothers milk.

 

Totally agree Vandal. I tend to put it in high going down long, steep grades. Less chance of over engine braking and have the back end outrun the front.
