Hi,

Newbie here! I recently bought my first ATV - an 01 Quadrunner 500 4x4, semi-auto, shaft driven. I love it...came with a plow/winch setup and all. Low miles, only 1250.

Problem is that after riding it for a short time (even 5-10 mins) and shifting down into neutral, the engine revs up to almost scary rpms. It doesnt die down until I shift in and out of 1st a couple times. Then when I go to shut it down, it lets off an incredible backfire. Am I doing something wrong or does this point to an issue someone is familiar with. Ive run through a tank of fuel, added stabilizer...but to no avail.

(I read through several threads and never found one similar to mine.)

Thanks!

Welcome to QUADCRAZY and Congrats on your first ATV!

Sounds like you are getting too much fuel and backpressure is building. Have you adjusted anything on the carb, like the idle screw? How does it start cold, does the choke work and does it idle well?

Hi, thank you for a response. The quad starts right up when cold with the choke set about half way. I release the choke back to the off position after about 2-3 minutes and she idles just fine. I can leave it idling like that for quite a while with no issues.

I have not adjusted the idling screw on the carb, what would be the best way of getting at it? And do I turn in a clock-wise or counter clock-wise manner? Thank you!

If it's the same as mine the idle adjustment is on the right side just under bowl. It's a cable style adjuster so it's "remote" so to speak. It should have KNOB look to it. Clockwise increases idle speed, counter decreases

Found the idle screw which had a gold knob over it. Gave it a couple small turns to lean it out and she is running much better now. This seems to have done the trick! Thank you all for the help.

      Looking for Quadrunner Flywheel Starter Clutch Gear race diameter
      By logray
      Hi all, 

      I am wondering if any of you have a Clutch Starter gear from a 1988 era quadrunner 250 sitting around that you could get me a precise measurement of the outer diameter of the race the sprag engages onto, for me? I need to machine a damaged race down and install a hardened sleeve and need that measurement (it's on a different gear than the OEM one, so I can't buy and use a OEM gear).

      First time quad owner looking for advice!
      By Mikey509
      Hi guys, I was given a 2000 Honda Recon fourtrax 250 (I think that's the full name lol). The previous owner had it sitting for a while before I got it. It sat for another few years in my ownership. I got it up and going on its first test drive today!! I was wondering where everyone buys their parts from?  Coming from the car community, we have sites like RockAuto and many more. Anything like that for quads? Also would like to be pointed in a direction, if possible, for plastics. I am missing a few and would like to have it complete. I appreciate any input!

      2006 Arctic Cat Utility transmission drive shaft replacement.
      By Shorty51
      Good morning, I am new to the forum. I'm 75 years old and love getting ATVs back to usable condition. I particularly like the 2006-2009 Arctic Cat 250 Utility. I currently own 6. The 2006 I am working on only has reverse and low gear. The "drive shaft" in the transmission is completely stripped where the high gear would mesh. Has anyone on here replaced the shaft. I'm told I have to split the case. I was hoping that someone on here could let me know how hard it will be. I already have it stripped down to where the shaft coming in from the clutch side is the only thing left. I was hoping I could just remove the driven clutch and drive it out from there. Directions say different. Any help would be greatly appreciated.

      Chain guard solution 1987 Quadrunner LT230E
      By Yamahahahaha
      I'm in the middle of repairing damage from the chain coming off of this from the previous owner. (I learned this is somewhat common on these for various reasons.)
      What are you guys using to either help keep the chain correct and on the sprocket or guarding your engine in the case that it comes off / breaks?
      Is there an upgraded guard that can bolt around the sprocket in replacement of the currently broken OEM alluminum?
