Uxv500 atv is running hot

The 20 Amp fuse (diagram shows only one 20A) feeds ignition coil and fuel pump circuits. With a current probe measure the two circuits separately to identify which is most probable cause.

Check battery voltage with engine running. It should be well over 13 VDC.

If it will run for a few minutes, you might get by with a touch test of the ignition coil and fuel pump. If one is markedly hot, the heat likely identifies the culprit. But a current probe is the tool necessary if you want to avoid part$ swapping.

Recommend fuel pressure check also. Eccessively high pressure could be problematic and low pressure would further implicate fuel pump.

Mixture is off when warm - look up how to adjust, I would suggest that is is running rich

Sounds like it is running lean. Adjust the air fuel mixture. If that does not help, may need to do some carb work.

FAN IS SHORTING OUT GETTING HOT,FAN NEEDS REPLACED

oil cooler is plugged go pressure wash it and clean it if that don't work cracked head

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.

Why do you think its running hot? Change the oil to a little heavier in the summer. pressure wash the cylinder and head, radiator, remove the thermostat.

Check your carberutor - make sure you have the proper air fuel mixture - running too lean (without enough actual gasoline) will cause the bike to run hot - but even more common than that is an ignition issue - either a bad plug, rectifier, coil etc. something not giving the proper spark or something with your cdi - best to check the plug, then power coming from coil, check rectifier, your timing could be off as well - but i've seen the lean issue and iginition electrical issue be the main causes of an engine running super hot like that.

check your oil filter, blow air through the lines to the rad. make sure the motor isnt running lean too. (red hot exhaust)
