remember on early models there was a safety pin that had to be held to switch to reverse,,,your 500 does this automatically so check for safety pin hookup. Could be brush or grass jammed in where it moves.

I remember the recall was for hawkeyes sold to people living in high elevations. you probably just need to clean your carb.

I would say based on information that the ignition switch is faulty,worn, or broken and would need to be replaced. Just to double check , it should remain in the acc position and not go back, doubt it would be financially or otherwise attempt to do a repair.

Sounds like one of the wires on the loom might have come undone, just run through the loom, especially all the wires to the ignition.If that fails, looking at the model, could potentially be a CDI failure. Good luck

Based on information provided I would start with just checking the basics as far as servicing goes, starting with air filter, is it clean, and is there anything preventing it from breathing easily. Check the accelerator cabling, might be dry, stuck or mucky somewhere from pedal to carburetor that can cause similar problems. Check oil level of motor as well.. Hope this helps

run the fault codes possible tat the winch is wired in correctly and is not allowing the alternator to fully charge the electronic system

The over RIDE button is not used for shifting. it is used to over RIDE the REV LIMETER while in reverse ( for applications such as plowing) shifting into 4wd while moving is safe on some vehicles, but can cause catastrophic damage on others. be ABSOLUTELY sure your vehicle is designed for SHIFT ON THE FLY . If you aren sure, then come to a complete stop befor shifting.

I would look for any excessive water or moisture hidden in an electrical component, or corrosion in any connection points.. double chech that you are using the correct amps fuse

With the engine NOT running, have a friend ROCK the bike forward and backward while you sit on the bike applying pressure to the shifter

Faulty fuel filter. Fuel filter installed backwards. Bent fuel line.

If the switches are working I would suggest a new start relay

Sounds like the carb,has it been check after its test and tune ?

Sounds like two diffrent problems ,but the leaking of the coolent could be radiator ,bad hose or thermostat .If the oil is leaking it might have a sensor so you dont blow the motor ..I hope this helps ..If any thing please call local Polaris dealer so no futher damage ..Have a great xmas !

coil maybe bad. lots of reasons here cdi maybe bad i would try boot on spark plug wire first screws off and back on with new one

sounds like its running rich. check your float height and then lower your main jet needle a notch

you nee to locate the battery wire on the starter then with a test light or meter put the probe on the post of the starter and it the start button, you should have 12 v at that point if so replace the starter, if not the check the solenoid

if its a black smoke its running rich. check your air filter and air tube for clogs. something may have made a nest in there.

I don't have a trial boss 250 but on most 2stroke engines you should never see the top of the piston through the intake port when the carb is removed as the piston doesn't go low enough, thats by design, its the exhaust side you need to look through to see the piston top(crown), if you remove the exhaust to have a look check the condition of the piston rings while there
