2001 Suzuki QuadRunner 500 High Idle

Recommended Posts

Hey everyone im new here, i have a problem with my 2001 suzuki quadrunner 500. When i start the bike up it sounds fine but a few seconds later the idle speed just keeps rising to where you cant put it in gear, and if im lucky it will climb down to where i can put it in gear but when i press the gas it immediately want to die. Please help me!

Check and see the choke, it may be stuck.  Double check that and the cable but look good because sometimes it’s the choke connector inside the carburetor. 

If that’s all clear it’s possible that the carburetor needs an adjustment. But you have to figure out why because if it was running good and just started acting up then you have to find out what.  So  if the bike was fine before then something changed that.  Maybe a piece of debris/dirt got into the carburetor somehow, maybe form dirt inside the tank, bad gas who knows. 

Also look at the air intake and make sure filters are all good and nothing got sucked into the carburetor like a piece of the air filter if it was crumbling. 

I would start there.

It did this when i got it but the starter went bad and had to wait for it to come in the mail, i got the bike a week and a half ago. I will check the choke and filter tomorrow, thank you very much

Check  also  for a weak return  spring on the  main  jet needle diaphragm allowing the  carb to  creep  open  above idle ,  and make sure there is no air leak between the  cab and intake . There could be a partially  plugged  jet making the  carb run  lean. That will  make it rev  high at  idle  and die  when you open the throttle . Before digging deeper ,  check the idle air  adjustment.  Most  carbs  are set from about  3/4  to  1  1/2  turns out from gently  seated. Try turning yours in or  out about a 1/4  turn  at a time to  find the best  spot   for idle and no stall. It sounds like it is  burning  lean right now

      I have a 01 blaster kickstart won’t work but bump start does work

      Not sure how many of you will remember this or give a crap about it but back in 2016 I picked up my first old atv to rebuild. Yamaha bear tracker 250. I picked it up in NJ while I was out looking for a quad for my little guy since he started this atv thing after seeing a few old pictures of me in my hay day riding. 
       
      The person I was getting the 50cc quad had this one laying around and asked if I was interested in it.  It was beat up and hadn’t ran in a few years.  No spark the guy said and he left it to sit.  I wound up taking both bikes. 
      I wish I had pics but I deleted the original post on Quadcrazy and lost the old ones on my phone when I upgraded. 
      This was the atv that caused me to stumble upon Quadcrazy since I needed a little help with the spark issue.  So needless to say I fixed it, did some cosmetic work and she was good to go. I took it upstate and used the shit out of it for just about everything under the sun. This atv made it through some deep snow, mud etc. I decided to leave it up there and use it as a back up since it’s been about 50 atv’s later and I have newer machines now. But unfortunately it sat for some time and it’s a little beat up so I brought it back home and going to clean it up. Amazing how one year sitting has done so much damage. 
      This was the first atv that I owned in over 30 years! It’s the atv that brought me here to Quadcrazy where now I endlessly check the site to see what’s going on, who’s talking about what and who can we help with there problem or can help me with mine as well as the on slot of what I do today as a hobby with atv’s. It’s been a great pass time for me and my son with the projects we have gotten and get into. He’s learned how to ride so well it scares me a little watching him. He’s learned how to fix, maintain and upgrade atv’s. He’s insanely good with carburetors as well. 
      It’s a good thing when a kid wants to play in the garage over his X Box!!
      The funny thing about this bike is that when we finished it we thought it was the best thing! We were missing a rack on the front and didn’t care since it looked ok, had no clue where to get parts or how to fix plastics. I was so new to this again since I was staring all over again and now had to remember things and also teach my son!  
      So we will be tearing into the bear tracker to get her up and running again as well as maybe a few new cosmetic changes and hang on to her for a while since I love this bike.  The last two pics are the bike the day we finished putting it all back together and when it was upstate for the first week. 
       
      Had no intention of this post going so long. 🤷🏻‍♂️

      So this '02 Taurus with only 87k miles on her starts right up every time multiple times a day except for twice in the last 3 weeks. The first time was 3 weeks ago and the second was today. It happened the same both times. Turn the key and stop to let the pump prime, then when I turn to the start position the engine turns real slow and sort of in fits. Usually when a battery is low the engine turns slow but in rhythm. During my 2 starts the engine barely seemed to turn and the crankshaft rpm seemed to vary. On both starting events I let off the key and tried to start 2-3 times with rests in between. But then eventually on the 4th try it starts right up just as quickly as a normal start.

      I have No clue as to what might be causing this. Only thing I know to do is, next time it does this to put a voltage meter on the battery to see if it's weak. Actually though, because both events the engine ended up starting up like normal that would indicate something other than the batt. Electrically this car is a little odd though. The interior light never comes on when the doors are opened, for years, and then last week it comes on twice when one of the rear doors is opened.

      Looking to purchase a windshield for my ATV, suggestions of what to buy with quality in mind and will fit without doing any modifications. 
    • By Kaj Colum
      Pushing the start button the engine turns and will forever without starting. But if I use the kick start it will start with one or two kicks everytime, any idea as to what is going on. New good battery and coil, I'm ready to try anything. It's a great bike, but this is getting anoying. Thank you.

      Anyone familiar with these models? Its a new to me quad, picked it up for basically nothing... Just time and materials now, this looks expensive.

      So Id say about 2 years back I bought a 2013 Polaris Sportsman 500 H.O. off of my uncle. It ran perfectly, nothing wrong at all. I usually go mudding with it or just ride trails with buddies. So as you would assume, the quad is quite dirty from sitting for a few weeks.
       
      STUTTERING PROBLEM: I noticed one day out of nowhere that in high gear at 15-20 MPH, I was already maxed out at 4500-5000 RPM  It would get to 15-20 mph, max out on rpms and start sputtering. It sounded like it was basically acting like it couldn’t go any faster than this.
       
      IDLING PROBLEM: I was fucking with the carberator the other day maybe thinking that is causing my sputtering, and now my idle will shoot up to 2600 on start usually, then I will turn the throttle adjustment down to the normal 1400. The rpms with then fluctuate 10-30 rpms back and forth repeatedly, it will then run for about another 30-60 seconds and the RPMs will slowly drop to about 900-1000 RPM and stall out. I replaced the carburetor and everything seems to be working perfect on that, no leaks and what not but it’s still acting strange. Also, I’ve noticed that when looking into the Electronic Throttle Control that two plates that aren’t supposed to touch have to be WAY past touching to even try to fire up. Even when set at a wide open throttle like that, I still have to give it some throttle to get it to fire up.
       
      Here is what I have done so far: 
      Checked the belt and clutch
      Changed out spark plug (Last one was covered in carbon)
      Cleaned the intake and air box
      Replaced the carburetor
      Replaced the inline fuel filter
      Checked that all lines on carburetor are connected into the right spots
      Checked If intake boot was cracked (Not from what I can see)
      Unhooked and reattached new carburetor (About 4-5 times)
      Cleaned battery terminals and battery off
      Shut on and off Gas Line Cutoff Valve
       
       
       
      My next thoughts are that maybe the TPS is fucked up or maybe the Spark Arrestor is plugged with mud. I was thinking tomorrow to purge the exhaust and also check the ohms output on the TPS.
       
      ANY HELP IS GREATLY APPRECIATED. I HAVE BEEN BATTLING THIS FOR WEEK AND REALLY WANT TO GO RIDING. THANK YOU!
