A number of 2007 Polaris models fitted with the 700 Cleanfire engine may experience a hesitation when the throttle is applied abruptly, attempting to accelerate quickly. Polaris has found a build-up of air in the pressurized fuel system to be the cause of the hesitation.
To prevent this occurrence, Polaris has developed a “vapor separator kit†which includes a new fuel filter with a vapor bleed port to eliminate this situation. Basically, the kit allows the system to “burp†and is very effective at eliminating the hesitation during acceleration.
