Question about Polaris ATV

HOT CHECK ENGINE on display when ridden fast.

The machine is an 07 model sportsman 500 with about 67 hrs on it. Ever since it hit 50 hrs the "hot check engine" flashes on the speedo whenever it's ridden for a while. I've replaced the thermostat, changed the oil, air filter and spark plug, flushed and refilled the radiator. It doesn't seem to be running hot (not boiling over, doesn't smell hot) but if I shut it off while the code is flashing it's hard to start and idles rough. If I just sit and idle for a few minutes the code clears and it immediately runs perfect til the code comes back.

Check your sensors. One is likely loose or dirty. Check one on your intake and at the end of your throttle body.

Polaris sportsman 500 HO shows hot check engin? what must i do


check your timing advance. It may be advanced a little too much. If that is okay, then make sure your spark plug is the proper one and not a sub. Most ATV's use DENSO plugs and these seem to work the best. (Having a spark with a higher heat range will cause the overheat condition). The other thing is your mixture... you may be running a tad rich.. lean it up 1/8 of a turn. Finally, remove the exhaust pipe and see if they is carbon build-up at the exhaust port... lean it over and remove all you can, careful not to allow any to fall into the engine. (Blocking the exhaust will cause a dramatic temperature increase.)

I have a 2004 polaris sportsman 500 when it gets hot it cuts off and back fires


Does the cooling fan ever run when the engine is hot? If not, you may have a problem with the fan thermostat.

For the record, spray carburetor cleaner does no good if it's sprayed on the outside of the carburetor with the engine running. That's not what it's for.

"engine hot" light flashes


Get codes from the dianbostic computer reader at Pep Boys/ Autozone etc. or the dealer.
This should tell you which sensor is out

Atv transmission


sounds like the connecting rod on the crankshaft.
i would inspect the primary clutch first before an engine teardown. Sometimes the engine shifts on the engine mounts and the clutch hits the cover, also check to make sure belt is not slapping around in cover.
