When to turn it off, the spark plugs stop instantly but the fuel is still sucked into the combustion chamber. your idle might be adjusted too high. try using a higher octane fuel

Polaris 325 magnum

It sounds like it could possibly be the ring gear in the rear differential. (Where the drive shaft enters the diff.) If the ring gear gets stripped the drive shaft will turn but it's not transferring that power to the rear axle. Lift the rear end off the ground and spin the rear wheel by hand. Listen for a clicking sound at the rear differential. If it is clicking then I would bet the ring gear is stripped.

My Polaris Magnum 325 won't start

The coil could be bad. That's the thing that the plug wire goes into at the other end of the plug.

I have 04 polaris magnum 330 it run great juste for iddle i dont push the throtle beacause de motor spark with fire in the carbs but on iddle motor run great ????? cdi or carbs

This could also be valve lash adjustment or bad intake valve ( burnt valves) this could also be dirty carbs. I don't think this would be an ignition problem. Clean out the carbs and check the valve lash on the intake and exhaust valves.

By straight work g fan is not a repair. The fan running constant will cause it to fail prematurely. You should replaced faulted electrical component.

What would cause a 325 magnum not get fire to sparkplug. The engine will turn over just fine and I have put in a new sparkplug and still will not get fire to sparkplug

More than likely the throttle shut off mechanism that is under a platic cover on the top/right side of the handlebar is the concern. The contacts maybe touching causing a no spark condition. There is an adjustment on the cable that runs to this shut off switch, from here the contatcs can be adjusted so they do not touch.
