Why is my Polaris backfiring?

Why is my Polaris backfiring?

Backfiring occurs when one (or more) spark plug in the ATV engine ignites the fuel when it’s out of turn in the chamber, and the exhaust valve on the cylinder is open. In other words, ATV backfiring occurs due to a short, sudden instance when the engine is too lean or too rich.

What kind of trouble does a Polaris Ranger have?

It has no trouble codes. I have a 2014 570 Ranger Midsize with 5000kms on it. After riding for a couple hours it will suddenly loose power and backfires and then slowly stall out – sometimes I can keep it running by pumping the throttle but most of the time it just dies.

Why does my Polaris Pro Bike pop under load?

Also, if I’m cruising along in high gear, it doesn’t have issues. Steady throttle seems to be ok except around 3/4-WOT. Even under load. So it runs like crap acceleration from 1/4 throttle to WOT but at WOT for a few seconds, will clear out and run good for 10 sec or so before wanting to die.

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.
