I own a 2007 Polaris Ranger 700. It has a 6" Gorilla lift, Gorilla axles, and 30" mudlite tires. I have recently replaced the stock drive belt with a EPI extreme duty after market belt. My question is this, the Ranger drives fine when the motor is cold but once the motor gets up to operating temp it starts to hesitate and sputter like it wants to cut off but doesn't. The higher the RPM's the worst it is. I have flushed the gas tank so I dont think its bad gas. Could this be a worn clutch? Any help would be much appreciated.
