Hello, I just purchased a used RZR 800 EFI. I love the thing, but sometimes when you are going down a hill, It will backfire real loud. It will also bog down at half throttle sometimes and miss real bad, But you can usually overcome this by pushing down on the throttle. I have checked the air filter, and all connections. I don't know where to begin. Somedays it will run great with great throttle response and sometimes it is real sluggish. Also, how do you set the clock in this thing. I have held down the yellow button for 2 minutes solid and it will not change. Any help would be appreciated. thank you.

If it is all stock and no modifications it sound like a out of spec TPS sensor, the backfire would be unburnt gas in the exhaust because of a rich condition, If it is new take it back to the dealer and have it fixed.

Its an 08 and no I bought it off an individual. Where is the sensor located and how much are they? Check engine light is not on. It is stock. Would this also cause the sometimes sluggish and sometimes miss pulling a hill? Thanks for the reply.

They are around $125 and yes it would effect the way it runs at any RPM and or load. the computer is a very basic piece of equipment compared to one that a automobile would use and it does not monitor the exhaust so it will not always trip the light. it does not care what comes out the tail pipe to cause a warning, there is no O2 sensor. there is several posting on the TPS sensor on this forum and what to do also and the same with the Tmap/Tbap sensor service. the TPS sensor is on the side of the throttle body and there is a procedure for the replacement.
