I have a 2003 Kodiak 450. When I am working around the yard, my cooling fan comes on normally and my ATV runs great. When i take it off roading, they cooling fan doesn't seem to come on and whenever i take it through water, the ATV shut off and does not restart for a couple of minutes. Any suggestions?

The pilot jet is plugged up. Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).

Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. remove the carburetor from the engine.

Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. About 3/8" from the main jet you will see a small brass screw. This is the pilot jet adjuster. Turn the adjuster 1/2 turn counter clockwise. Make a scratch on the casing around the adjuster so that the scrach lines up with the slot on the screw. From this point, carefully count the number of turns until the adjuster can be removed. Spray carb cleaner into the jet then replace the adjuster using the same number of turns such that the screw slot lines up with the scratch mark.

Remove the idle screw and the air screw on the outside throat of the carb and spray into the screw holes as well. Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. This process should get you back on the road.

Please rate this solution. Thanks!

check the oil level in the differential. If run a long time low on oil it may have damaged gears and bearings. Look for leaks past seals and cover gasket.
