We have a 2000 Suzuki LTF 250 that we are having an issue with and a re looking to you members for ideas/help. This machine starts and runs great but after awhile when it gets hot (not overheated) but after 10 minutes or so it starts to bog down, loose power, miss etc. If I slow down too much it will stall and not restart until after it cools off again. This problem started happening AFTER we replaced the entire carburetor for a totally unrelated issue, so prior to that, it ran perfect. Any thoughts or ideas are welcomed. Thanks in advance.

Sounds like you have a bad CDI. They aren't cheap, so I would test all the other ignition components first. If you don't have a repair manual, buy one, there will be simple tests in there to check the coil and such. It will also have a troubleshooting guide that you may find helpful. Also, check your wiring for loose connections and bad grounds. It also wouldn't hurt to pull the plug the next time the machine dies on you, ground it against the motor and check for spark, just to comfirm that the problem is in the ignition.

my ltf250 4x4 had the same problem. i replaced the plug and adjusted the carb because it had a fouled plug when i pulled it out. try a new plug and maybe a fuel pump because my fuel pump went bad and it did the same thing, like there was a vaccum leak. and there also may be air in the fuel line and pump

      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.

      First thanks for any help guys, new to the forums and it's gotten me this far. I bought a 2001 bear tracker 250 for my family to get around the dirt bikes races. It wasn't running right and had a high idle. Previous owner thought it was a carb problem, so he ordered a new Zoom carb and new intake boot, but it still had the same high idle. ( I believe he had the throttle cable adjusted wrong, because it idled fine when I put it back together) So I tore down and cleaned the stock carb, and it started up and idled fine, but needed to have the choke 1/2 out to run.  I swapped to the new zoom carb and had the same issue. Choke half out bike ran ok. I played with the needle and the pilot screw with no change. ( bike did seem to be running rich though, but didn't get better when I tightened pilot screw or raised meddle) I Took it to the races and once I started bouncing around in the cattle fields the quad started cutting out real bad. It would barely run.  Sometimes it would run with choke off, sometimes choke 1/2, sometime choke full. I cleaned carb again, checked float level, and boots, no change still wouldn't run. Then suddenly it started running ok again.  This makes me believe it's an electrical issue rather then carb. I know there's no air leak, it's been checked, both carbs are clean( I've swapped them out a couple times, it starts up immediately and usually idles fine. But then bogs down/ or stutters under throttle. I saw the post on the guy who disconnected his rectifier and reconnected and suddenly it started working again, which lead me to believe it may be electrical and not carb.  So any advice on what I should check? Any way to test the CDI or rectifier?  Once again, I appreciate your help.

      I’ve got a 2000 400ex with a dg slip on muffler, it came with he stock muffler on it but the previous owner had the dg in a box so I put it on. I’ve been riding it for the past month and a half and every time I let off it backfires, and the other day the backfires got way louder, 2x louder! I’m concerned that I may hurt my motor? Why does is backfire??? Thanks

      What should I do about this , bad oil leak where the filter cover bolts on . Can I use some gasket maker

      I'm working on my uncles grizzly and it sparks once on initial cranking then no more after that. If I let off the start button then press the start button again it will spark once then stop sparking. I was wondering if anyone seen this issue before.  Also I've never used forums before so sorry if this question is in the wrong location.
