Polaris classic 1997 500 when warm out loads up . run down trail at about 20mph feathering gas at about 3/4 then after awhile well clear out and the next time slow down start all over again . this is only when its warm out changed plug s from 8 to 9

I am working on the same machine that has not been running for quite awhile. I'll let you know what I learn. Did you find a manual? Gus

Run some Sea Foam in the gas it will clean the carb sounds like a sticky jet or dirty carb the Sea Foam will clean the carb of any residue or deposits that have built up in the carb over time causing it to malfunction you can get the Sea Foam at most parts stores and its cheap stuff and works awesome.

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

try using the choke...

hi, i have a 1987 polaris trail boss 4x4 was riding and gas was leaking from the under side front of gas tank, is there a hose from the carb there? Anyway when i noticed the gas leak we stopped and it slowly ideled down until it died and then would not start.
I have spark pulled carb and cleaned i get gas.
can you help?

sounds to me that you may need to re jet your carbs for the warmer weather. your local sled shop should hook you right up

I literally had the same exact problem yesterday and last year. Perfect from start up to about 2 hours in...then sounds like it's bogging down, then dies at a trail stop. Fired right back up in about 2 minutes. Also it happened on a lake burn..wanted to die, so I feathered the throttle, came right back to life just as strong as it should be. It has me stumped. If you figure it out, let me know and I'll do the same. Mine is an 03 Edge 800 XC SP.

maybe the carb needs cleaning

90 PSI IS A LITTLE LOW, COULD BE A CRANK SEAL LEAKING OR A CLUTCH OR BELT ISSUE.

check or change oil and clean around engine fins sound like engine getting to hot and vapor locking fuel
