I have a 2007 Polaris 550 touring deluxe and I need to set up the proper idle speed speed.

SOURCE: Changing fuel filter

The fuel filter is under the seat between the battery and the engine coolant tank, Whatta Bit*h to get to.

the high idle could be a dirty needle check your carbs i have that problem with my 550 rmk the reverse light could be your wire harness check your wires with any wire tester idk the specs for it but also clean your connections with some electrical wire component cleaner and use so di-electrical grease if all else fails you may need to bring it to a mechanic for a small fix like that it should run up that high

2005 600 edge touring Will not turn off on either kill switch or on the ignition

SOURCE: 2004 Polaris 600 edge touring Perc reverse not

check your engine idle speed..if idling too low it will not engage also check your belt deflection if too tight it will cause the engine speed to be too low causing the no reverse condition

Not an unusual problem, no recalls. Replace pads (and rotor, if necessary), but after brakes are bled, loosen the bolt between the rear caliper arm and the swing arm, have someone apply and hold rear brake, tighten bolt. The arm, which holds the caliper in line with the rotor, occasionally loosens and allows misalignment. Checking pad thickness on both sides of the disk regularly will reveal caliper problems if wear is not evenly distributed.
