Hi there,

Have you check the valves and the valve gaps?? Sometimes but not always having the wrong valve gaps can cause backfires. Have you also tried tweaking the carburetor to try and improve the idle??

First check fuses and switchs. You can get a wiring diagram at Ronnie's.com

check for a vacuum leak first... then suspect a idle control solenoid issue

My opinion, it's running rich and letting it idle for 5 minutes doesn't help. Whether it's carbed or EFI, when the machine is cold, it needs more fuel. As engine temperature increases, it doesn't need as much fuel, and the carbon that started building up on the plug is burned back off. When a machine isn't ran for very long, carbon deposits continue to build on the plug. The carb itself may need to be rejetted/adjusted, it it's running rich,

sounds like the coil is weak or the electronic spark box is goin fuel filter been changed ?right gap on the Plugs? need more imfo on it to do more thks

follow ur throttle cable down to cars there should be a plastic screw close to cable to adjust idea but with polaris that screw can be hard to find with all the plasticc they put in way but if u can see carbs easy enough u will see the idle screw

May be fouled plugs. If not check vent hose on carb.
