My rhino is about 6 months old and i never got it serviced yet. now it backfires at high rpms then cuts out, i can deffenetly feel a power loss, i cleaned the carbureator and the air filter.....problem not solved.....any thoughts? could it may be the oil or sparkplug? thank you....jerry

 

What size rhino? Where do you ride(conditions). How many miles are on your rhino?

 

660, i beat the **** out of it....train tracks, woods, rocks, mud, trails, feilds, hills, no clue about miles tho

 

were the valves ever adjusted ? If not that may be it!

 

Thats my first guess.

 

Two things here.

First check your fuel filter I would bet it is the culpret. I had mine clogged and I cleaned it out and then eventually replaced it. Problem fixed. [img]i/expressions/face-icon-small-happy.gif[/img]

Next make sure you had your initial tune up. The intake valves tighten up and the exhaust normally don't. So once the adjust them you should be in good shape.

My guess is the fuel filter behind the passenger seat.

One Bad Rhino

 

Was having the very same problem with my 600 Grizz. It would start and run at low speeds but as soon as I went into 240 Gordy mode it would miss and pop and weeze... After setting all winter I tryed to start it so I could load up and go spend $200 to have the carb rebuilt. Wouldn't start.

I pulled the plug and took a good look a the spark... Guess what? There was very little and it was sparking around the post. A minor adjustment and I am now ready to push over schools again..

Good luck
