Stalls when riding not just idling.

Recommended Posts

It idles just fine. I can ride it in the backyard and not have any issues. It only does it after being held open at high RPMs for more than 30 seconds. Then it seems like it is starting to bog down then dies. Then it starts right back up. 2002 linhai 260

Sounds like  fuel  starvation. Something is restricting the fuel  entering the  carb. Some carbs  have a  screen  on the carb's fuel  inlet  and it  could be  plugged  or   a pinched or   otherwise restricted fuel  line  would be  my  guess.   For whatever  the  fuel  bowl  isn't  staying  full under  high demand.

But I can hold it wide open in the garage and it runs fine (little black smoke on the high end but doesn't  stall)

Wide open   and not in gear does not require anywhere  near the fuel  flow   it  does under  load.   I  don't  of any  other reason  it would  die  out  the  way  you describe if it  is  not  fuel starvation.

Try checking the breather hose on the carb.  It might be plugged. Had same issue on my 1994 big bear. Had a chunk of mud in hose. After blowing it out it ran like new.

I agree, sounds like fuel starvation under load...the carb is running dry. maybe its a float issue, sticking a bit?

Sticking  float ,  restricted  fuel  line  or plugged  vent  could all   cause those symptoms .  Start with  checking   for  a  restricted  fuel  line or plugged  vent  before tearing into the  carb.

      I have a 2000 Polaris Sportsman 500. A year or so ago we got it running after replacing the kill switch. It ran great but after some use for a couple months it got a flat tire and for some reason we just forgot about it and it sat for some time. Before it sat i replaced the gas cap, fuel filter, fuel pump, petcock, battery, starter relay, oil and oil filter. I recently went to start it and it started so quickly and without choke or throttle but the ATV wouldn't move till about 1/4 throttle and it wasn't really a smooth ride until 1/2 throttle. it also would bog out randomly after you came to a stop and sounded like it was getting too much fuel. I cleaned the carb and adjusted the air/fuel screw to 1 3/4 turns out.  I also messed with the idle and the throttle cable adjuster up on the handlebars. It's safe to say it now runs worse than when i started working on it 2 days ago. It takes more effort to get started and bogs out idling after about 30 seconds. I tried adjusting the idle but every time i do it'll get to a sweet spot but after driving it down the driveway and back the idle will go up and down to the point where i can't put it in gear because the gears will grind. Any thoughts or ideas would be greatly appreciated. Thanks

      Any ppl from Perth give advice on the best places to ride in WA.

      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!
