I have been sorting out some of the problems on a new to us 500 x2 and it seems I may have a sending unit problem. I bought a new gauge cluster and once that was hooked up, I see the fuel level bar graph flashes constantly.

 

Watched a yt video about a similar problem and it looks like a cleaning is in order to get the fuel level working again. My question is - would replacing fuel pump, regulator, etc. be wise since I will be in there anyway? The machine runs fine and doesn't seem to have fuel delivery problems (yet - understand it only has an hour or two of use by us while I work on it).

Hi, did you ever get your fuel gauge sorted?  Don't know if it's helpful, but I helped my neighbor with his Hisun EFI ATV last year.  Electronic fuel gauge on the LCD cluster was acting up, so I took the sending unit right out of the tank and moved the float bank and forth and watched the gauge with the ignition on.  It worked but had a delay, you'd have to wait a few seconds for it to respond, guess like a snubber.  Anyway that seemed to fix the problem, bad connection or sticky float, or didn't know about the delay.  Hope this helps, cheers!~  Bellarmine

      2 problems with 2000 Timberwolf 4x4
      By Tim Keiper
      1st problem, Does anyone know where I can find a stock carb for my Timberwolf, I have tried two different aftermarket carbs and they both suck. The machine runs great until it gets good and warm, then it keeps stalling unless I feather the throttle. it will even stall while I'm trying to go from 1st to reverse or vise versa. I took it to a buddy of mine who is a bike mechanic for years, and he told me try to find a factory carb. When I look online from dealers it says "NOT AVAILABLE" anyone have any suggestions ?
       
      2nd, The small tab on the rear axle for towing is to short for even pulling my small yard trailer, I can't even turn a little bit and hit hits. I tried making an extension which worked great as far as length, but it bends the tab and then the extension drags the ground. I have an idea of what to do to fix it, but wanted to see if anyone else has had this problem and see how you solved it.

      I just bought a rare beast!

      Hello All
      I'm kinda new to ATVs. I just bought a 1987 Suzuki quad runner 230 Dual Range. I'm having a problem finding info on it. It's very clean, only 2.800 miles. The front wheels are only 30 in.center to center. I was thinking about adding wheel spacers to give it more stability. I realize the added stress on ball joints and bearings. I'm wondering if there are any other concerns? Any input is greatly appreciated!

      2003 Kodiak Leaking fuel from drain hose at bottom of carb
      By DPDISXR4Ti
      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...

      1996 Polaris Sportsman 500 4x4 Issues with high gear
      By Sportsman500guy
      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
