Why does my ATV bog down and die when I keep the throttle wide open?


If you are lucky, you might just need new fuel filter and the fuel bowl cleaned out, and maybe new air filter. If not so lucky you need carburetor rebuilt. Backfire is usaully caused by engine running too lean ( too much air for the amount of fuel present). Fuel bowls get gunk in them and the fuel needles and fuel jets get varnished up. The accelerator pump gets worn out gaskets and/or bellows and doesn't give the right amount of fuel mist when you accelerate.

Full Choke is indicative of a motor starved for fuel

My 2007 450 sportsman won.t start but she backfires


Remove the seat, and take the cover off the air filter container. Place your hand over the end to aid in fuel flow to the carburator. You might not be getting enough fuel which is causing it to backfire and not start completely.
Attempt to start the ATV once you get fuel flowing you should be all set. Clean that filter as well.

'94 Timberwolf 250 2X4 starts great when I have battery charger hooked up, coughs, backfires and dies when I unhook the charger. NEW Battery, fully charged, seems to crank well when charger is OFF, but...


Hey Ccp.. A new battery and it did not help the cranking issue?? hhmm... PLEASE take the battery and have the CCA (Cold Cranking Amps) checked... just because its new and has voltage does not mean its a "good battery"... It takes AMPERAGE to crank and run your machine.. (*see 35 amp fast charge!!)..Autozone, O'reilly's, a battery shop can check the CCA... once you have MADE SURE the battery is good, then you can proceed to diagnosing the real issue...This is the procedure a professional mechanic takes..so do this first... once you have determined the battery is (good or you got a new one)..and ... once you have the machine running,,WITHOUT a charger hooked up.. time to check the output.. you should get 13.5+ volts at 3000+rpm.. if you are not getting 13.5+ volts, its time for electrical diagnosis...This manual should have all the electrical specifications needed to diagnose your issues...
