Question RZR 170 Help!!!!

I really hope someone on here can help me out. My son has a 2011 RZR 170. We have had it for almonst a year and it has ran perfect. He is supposed to be going on a ride with his Gradfather later this week, and low and behold now it's acting up. It started a few days ago stumbing at anything over about 1/4 throttle. I figured maybe the plug was bad so I replaced it today, but it's still stumbling. It idles fine, and runs fine as long as you don't try to gas it. I may have to take it to a dealer, but I was hoping sombody on here could tell me were to start. It almost acts like it's starving for fuel. I know the plug is good, and the fuel is fresh. This just started out of the blue. One thing I noticed today was quite a bit of oil in the airbox. I'm told this is common, but could that have caused a problem with the carb? Any ideas?

Thanks,
Brad

You may just start by running some seafoam mixed in with the gas, and try to stumble through an entire tank of treated gas (maybe more, maybe less) that way. A couple weeks is long enough for untreated gas to start to turn into gel inside some parts of the carb, such as the jet passageways. The smaller the amount of fuel (i.e. jets, bowl, etc), the faster it goes bad. That is if you didnt treat the gas with a stabilizer before that. I would also check the airbox to make sure the airfilter is somewhat clean, and there is no debris or anything inside restricting air flow. Airboxs are a prime choice for rodents to make nests in, just another thought.

It is something simple, cheap, and easy to do, and may be all that the machine needs.

I am unfamiliar with oil in the airbox issues on these machines. I will have to do some looking into on that part.

I have a 2016 rzr 170. it went on its side and after that has been hard to start. We rebuilt the carb but it is still hard to start it just turns over and if you apply the throttle it leaks gas. any idea of what is going on

It's fuel injected - need to find out where the fuel is leaking from - it may be the cause of hard starting or the valves may just need adjusted
