I was running cat 500 at low speeds for about 25 minutes today, i mean very low 3-5mph then to zero back to 5 so on so on, and when I parked my radiator was bubblin over a bit and steaming with a little cooloant leaking from somewhere but not much. My question is about cooloing fan, i never hear it engage or running. My Honda you have to leave the key on for a few minutes to let the fan run before shutting down, but my Cat i cant find anything in owner man. except "keep it free of debris with hose". How do I know if cooling fan is operating properly, should i hear it after shutting down engine. Its a 2005 but i only have 252 miles on it. Any info would be of help and thank you to everyone for your help with carb and fuel overflow, there was dirt in carb, took apart and cleaned myself w/no prob now works great, even though i did not install in line fuel filter. Where do I get one? Thanks again!!

A dealer will be able to get you the fuel filter. As far as the cooling fan goes, it sounds to me like it isn't working and when you aren't riding fast enough to get a good breeze going over the radiator, it is going to overheat. Check the wiring, and any fuses. Sit there physically watch the fan while the machine is warm and running, see if it comes on at all. You may have a faulty temp. sensor or fan relay. You might try running power straight to the fan from the battery to make sure the fan itself works.

He is right, if you shut off the engine and then leave the key in the on position, the fan should still run until the temperature drops. Good possibility is some crud got in stopping the fan and blowing the fuse.

Don't forget to check your thermostat. It is easy to remove and place in hot water to see if it opens. You can also check the temp of your radiator (non contact thermometer). If the radiator is not getting hot the fan sensor will never tell the fan to come on.

Did you hook the fan up to 12v yet and see if it works? If the fan is broke you can get a replacement from any parts place for about $50.

      As the 2025 ATV Motocross National Championship Series (ATVMX), an AMA National Championship, got underway with back-to-back Florida AMA Pro only events, it was evident that Phoenix Racing Yamaha’s Joel Hetrick picked up where he left off last season.View the full article

      I hadn't driven my Kodiak for a two months, and since it was low on fuel, the first thing I did was filled it up to maybe 7/8 full. Getting ready to start it, I rotated the fuel selector switch to "on" and within seconds I smelled and saw fuel dripping onto the floor. I quickly turned it off and the fuel gradually stopped - I can repeat this.
      The fuel is flowing from the hose that is connected to the bottom of the carb, and routes around to the left side toward the wheel well. Any idea what's going on here? It ran fine the last time I had it out.
      Thanks...

      If anyone is having issues with the Mikuni VM24SS carb, I thought I would post what issues I had and how I resolved them.
      Acquired a 93 Bayou 220 that had sat for over 4 years.
      The carb was extremely corroded and pitted and full of leftover fuel.
      Cleaned carb and bowl and was able to get the engine to start.
      Within 30 seconds exhaust would heat up and start to glow red hot.
      Removed carb and recleaned everything, including a second overnight soak.
      Needless to say, after removing the carb for the 5th time and my frustration to the limit I
      realized that my attention had been to the carb body and not to the bowl.
      There is a small brass rod on the bottom of the carb that goes down into the float bowl but is seperated from the main section. I had cleaned that area very well....I had thought.
      ***The corrosion had sealed off the channel that runs from the main bowl section to the small tube section on the side of the float bowl. No amount of carb cleaner was going to get it to budge. So i took a small nail and started to scrape away the corrosion and was eventually able to dislodge enought of the corrosion that carb cleaner would flow through that channel. ***
      I thoroughly cleaned each side of the channel in the float bowl and reinstalled the carb and now the issue of it running lean is gone.
      On a second note the fuel mixture screw was a nightmare to remove as the threads had been corroded and wouldnt let the screw come out. I used a little cutting oil and worked the mixture screw in and out until I was able to push past the corroded threads and completely remove the needle. After a couple passes with a tap to clean the threads it is like new again.
      Hope this helps if you are having a lean running machine.

      Does the 1987 moto 4 350 have a low oil sensor that kills spark? Or are these too old for that kind of thing?

      I bought a 1996 Sportsman 500 4x4 about a month ago, and I love it. Unfortunately, I've been experiencing a few problems with the high-range gear. The first problem is that the gear selector will intermittently pop out of high and into neutral. This problem will sometimes occur when starting from a stop and sometimes will also occur while at cruising speed. The last time this happened I stopped and put it back into gear, however, as soon as I tried to throttle the machine would die. I turned it on again with no problems put it back into high and it died again. Once again I turned it on with no problems put it into low instead and it worked fine with no problem. I drove in low down the road slowly for a little and then shifted back into high with no issues. 
         I plan on working on it this weekend and would just like some opinions or feedback from anyone who may have experienced these problems before. I'm very mechanically inclined but im unsure of exactly where to start as this is the first Polaris ATV that I've owned. Any feedback is appreciated and thanks in advance
