03 Sportsman 600 will only run at idle

[gradykraft]

I have a 03 Sportsman 600 that will only run at idle. When I try to accelerate it bogs, backfires, and dies. I recently replaced the crank seal, stator, magneto, cdi, coil, and voltage regulator. I have also cleaned the carb and replaced all the jets. It has a brand new battery, fresh oil change, and air filter. I am out of ideas, please help, its time to ride! Thanks.

If that thing sat all winter, I know it sounds too easy, but water in the gas tank will do the same thing. Even if you cleaned the carb, water will sink to the bottom of your tank and that's the first thing to burn. If our machines sit for a bit, I'll usually drain some gas out of the reservoir side, as it's the lowest part of the tank. Then run it for as long as I need to if it's sputtering. Let it idle, then slowly hit the throttle and try to keep it running. Keep doing that, and if it is water in your gas, it'll run smooth.. If you've tried that already, sorry. We've had to learn the hard way too..

Thanks cowslinger, I was overlooking the simple stuff after I put all the other work into it. I drained some gas, added a little heet and two cycle oil to the gas, and cleaned the carb again. It runs great! Glad to have that project done.

Great...funny how you sometimes think it's the hardest thing, when it's the easiest thing. I've done that myself...that's how I know!! lol
