Good morning everyone!:crying I am in need of some advice. I have reads several different threads with similar issues to what I am having, but want to check in with you all to get more feedback before I start taking my 570 apart! I know I am long winded, but I want you all to know the whole situation so I get the best advice.
I am handicap & would LOVE to ride my wheeler!
HERE'S WHAT I HAVE:
I have a 2014 Polaris Sportsman 570. It was owned by Polaris. Before purchasing it Polaris upgraded it to the 2015 revision [fuel injector upgrade and one other item]. I bought it with 348 miles on it and it now has around 380 miles on it.
Hours are very low.
HERE IS THE PROBLEM:
I have not been able to ride it for health reasons. When I parked it I left 87 octane gas in it WITHOUT stabilizer. I have had a trickle charger on it the entre time. I have not ridden it for well over a year. When I went to actually take it out I rode it for about a half of a mile. It ran a little rough, but I figured it would - old gas. I parked it and let it idle to run the old gas out of it. After a period of time it stalled out & died - wasn't there when it killed. Since then I have had nothing but trouble.
After it stalled I tried starting it and it ran REALLY rough - almost like a really gummed up carbureted machine, except this one has no carburetor. I couldn't get it to keep running. It would start and run for a short while & then die or it would not start.
HERE IS WHAT I HAVE DONE:
•Sucked out old gas & put in relatively new 93 octane, non-oxy with stabile & Seafoam in it. It ran enough to get it into the shed and that’s about it.
•My non-oxy gas was a month or two old so I then went & got completely fresh 93 octane, non-oxy with stabile & Seafoam. Didn’t make a difference.
•I knew the battery was old & a bit weak so I replaced it with a new AGM battery. It cranks over longer, but still no change.
•I talked with the local dealer and he said it was probably the spark plug. He recommended going from the Champion 977 plug to a NGK MR7F. Tried changing to a new plug twice. No difference. It may start & run for a short while or won’t start at all.
•I know the TPS is a problem on these machines sometimes & I have excess play in my throttle. I used a piece of a zip-tie to make sure the TPS was NOT making contact. It started for a short while & killed.
HELP:
Now I am at my wits end. ATV with low hours, low miles, barely used by me, and it won’t move. I know the fuel pressure regulating O-ring and/or the fuel pump can also be problems on these machines. The machine doesn’t have a Shrader valve port to check the fuel line pressure. I don’t want to tear into the machine & start replacing things unless I really need too; it isn’t easy for me to do anymore.
Let me hear your advice please!
