06 500 efi sportsman wont hardly run, backfires
Ok, I've been dealing with this for years now. At one point my sportsman sat around for about 2 yrs. I probably started it a total of 5 times. The last time I went to start it, it wouldnt hardly start, and when it did, it sputtered really bad when running. Then it wouldnt start back and the fuel pump failed.
I replaced the fuel pump, fuel filter, spark plug, and fuel injector. That was two years ago. It didnt help. I even took it to a dealer to work on it. I went to pick it up, and it still ran like crap. He sprayed a couple of cans of carb cleaner in the air filter with it wide open and it ran good up and down the parking lot. I've rode it as much as I can since then, and a couple of times it seemed ok..for awhile.
Heres what is presently happening, which isnt much different than the past few years. I can get it started initially, but if you give it gas, it dies. I spray carb cleaner in air filter, it runs for a few minutes, then starts bogging down, sputtering, and quits if you hold the throttle open. I wear my thumb out working the throttle to try to keep it running. It will surge forward a couple of feet, then nothing...work the throttle, surge, nothing....if it does go anywhere, it backfires a lot also. I'm fed up.
Any advice out there? Besides pushing it off a cliff?
