need a little help

[LT10]

took my rzr-s out for a couple hours today and it started cutting out under hard acceleration and load, not really bad to the point it was falling on its face but really noticeable. it also kinda seemed to come and go, at times it would do it a lot then it would seem to go away. so I'm looking for any advice i can get.

Thanks in advance

Do ya think maybe you're hitting the rev- limiter? At what RPM does it break up?

whats you fuel pressure?

whats you fuel pressure?

X2. Check the fuel pressure. Same thing happen to my Dads we checked the fuel press and it was around 22 psi it should be 39-40 psi.

well the way it felt fuel pressure would really make sense. unfortunately the rzr isn't with me it stays at my dads place since he lives right next to the dunes and it saves me a lot of money not to have to tow my trailer 200 miles every couple weekends. hopefully i can get over there this weekend and check fuel pressure. what all is needed to check it. have fuel pressure gauge but not sure if any kind of adapter is needed? and what are you seeing thats bad when you see low fuel pressure? bad pump?

thanks for the help everyone

Stick the fuel press gauge at the end of the injecter line at the top of the head on the shrader valve if the hose is long enough drive it up the street and see what it reads. if it's low then replace the fuel pump. Double check the correct fuel pressure I think it's 39-40 is where it should be. I hope this helps.

If you have to change the fuel pump I think you have to buy the tank and it comes with the fuel pump from polaris and it's pricey. There is a Napa ( I do not have the Napa# sorry) one that works or you can get one from Weller Racing and they are a supporter of this sit.
