How did I Fix my Polaris Sportsman EFI spitting?

I removed and cleaned the T-BAP sensor, fuel tank, fuel lines, fuel rail, and the throttle body. l also replaced the fuel filter and burned a whole tank of fuel treated with Sea Foam.

What causes popping and hesitating on Polaris Pro riders?

That kind of popping/backfiring. You know how if it’s advanced too far it starts real hard and rough but will rev to the moon, but if it’s retarded too much, it starts super fine but sputters and bucks and spits and kicks. Would a sheered woodruff key put off symptoms like this?

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 Polaris Sportsman not spit fuel?

Other than rough idling and the idle RPMs seemed low; the machine would go for hours and then all of sudden it would start doing the funky chicken like it was starved for fuel. I would wait about 15-20 minutes, start it right up, and all would be well again for the next day or two.
