Why does my ATV backfire when I slow down?
Low Fuel Pressure or Weak Fuel Pump—Like a clogged fuel filter, this would cause your engine to not get enough fuel to the combustion chamber. A Hole in the Exhaust—If there’s a hole in your exhaust system (muffler or tailpipe) near the engine, this would cause backfire.
What to do when your Polaris engine backfires?
If your engine seems to sputter/backfire upon de-acceleration, and doesn’t always idle smoothly, or, in extreme cases, not well at all, try adjusting the ETC. Follow the throttle cable where it exits the housing on the handlebar. Where it ‘bulges’, slide back the cover. There will be a threaded adjuster.
Why does my Polaris Pro rider keep popping?
No surging, no hick-ups. When you rev it, it blows. It sputters, backfires, pops..you name it. Not so much sitting still but every time when under load. And it’s probably from 1/4 throttle all the way up. At WOT after a few seconds, it seems to clear out and then it screams but if I keep it there too long, it wants to start stalling out on me.
What kind of car is a Polaris predator 500?
Pretty new to Polaris for that matter. I’m a life-long Honda & Arctic Cat guy. But now I have an ’05 Predator 500 and it’s driving me insane. I got it off a guy that said it ran last year and I kind of know him so I don’t think he’d have any reason to b/s me. It’s super clean and not really modded up.
Why does my ATV keep backfiring at idle?
Take note that most ATVs source fresh air at the junction of mufflers and header pipes. If there’s a leak along the system, the engine will keep backfiring. In some instances, a popping exhaust system indicates that the engine has an extremely lean idle circuit.
