Stop doing donuts.

 

Got enough gas in the tank?

 

Don't do Donuts x2

 

You keep doing donuts and you WILL roll it over.

 

FACT!!

 

 

jacobs..i work for jacobs, i recognized the "broken J". lol

 

Im surprised no one has said anything about a 900s cutting out question in the rs1 section.

Guess everyone is just focused on how he was getting it to cut out.

Just a thought but maybe he has to bend the rops in order for the wife to let him get a custom cage.

 

Or for the wife to get in.LOL

 

🍿

 

In all seriousness, low fuel will cause it to cut out after a few rounds of donuts.

 

As well as a roll over will also cause the fuel to cut to, and you will lose traction as well!

 

No donuts!!! You will roll and cut your arm off. Or your passenger's.

 

In keeping with not answering his actual concern, lol ; how cool is it that everyone calls them donuts and knows exactly what it is, east coast/ west coast. There’s not really another word for it.. props to whoever named that move!
also, donuts are dumb in a sxs..

 

Actually the op is here now. Credit for coming back.
Now to find out if this is a serious concern.

 

100% of people who do donuts long enough end up rolling their machine!
I'd say fuel issue or maybe a loose wire? No engine codes I presume?

 

I appreciate all the replies, especially the one's that offered suggestions about the actual problem with the engine cutting out. Plenty of fuel, can't see any loose wires, and no codes. It runs great other than this. As far as the safety concerns, I fully understand the risks. I'm 71 years old, and used to do some short dirt track racing in my younger days. I have a pretty good understanding of the physics of hanging the rear end out in a slide. My donuts aren't anything too crazy. Slow speed on our hard packed limerock roads, in an area that has 2 or 3 inches of sand on top. No ruts. Pretty tame stuff. I was really hoping that someone would have an idea about what this could be. I was starting to wonder if there might be some kind of "motion sensor" built in that detected a slide and idled the engine down. Oh well, thanks for the input.

 

No motion sensor or anti-donut safety devices. Is the battery strapped down?

 

When we suggest fuel we are thinking less than half a tank can slosh away from the pump and make it stumble. Donut to the left will get farther around than donut to the right. The pump is on the right side of center in the tank.

Other possibilities are:
Torn intake boots flexing and letting unmetered air in causing it to go lean.

As suggested above loose wire connection. This includes a battery moving in the battery box and temporarily killing the fuel pump and ignition.

Keep the rubber side down.
Let us know what you find that fixes it

 

I am glad you are aware of the risks so you must using wrist restraints or window nets. I see two arm amputations a week from RZR donuts.

 

While attempting donuts, are you using/applying the gas and brake at the same time??

 

 

Do-Nots.
That being said, if the tank is not completely full the centrifugal? force could be creating a temp void in the tank.
Is it possible your foot is sliding off the pedal? Sometimes I have to re-situate myself and my foot for that very reason.
Let us know if you figure it out

 

Bought a wrecked / rolled over 2020 pro xp4 with 41 miles on it back in 2021.

I wasn’t doing donuts but when it would get down to about 1/2-1/4 tank it would cut fuel, let off stab the throttle again and all was good. Though dang fuel pump must be going bad. Fast forward a couple more rides and same issue. So I bought a new fuel pump, pulled the old one and noticed the fuel pump had slid up in the holder so it was sitting on the bottom of the tank.

slid it back down added a couple zip ties so it can’t slide up.

ran that fuel pump for another 6k mile without ever cutting out again.

 

I’d say go ahead and order a skid plate package. Might as well do something useful while the bottom is easily accessible.

 

Yeah, replace your prop shaft before doing that.. I put my .50"HDPE skids on less than 200 miles ago, then got involved in a gear reduction, which pointed to new axles and prop shaft.. I hate the thought of tearing that miserable so and so out and putting it back on solo... it's built hell for stout, and I knew putting it on, that it'd have to come down a couple times a year for service and lubrication, but didn't expect it to be so soon..
