Good Evening! Have a 2015 570 Sportsman EFI that is about 1.5 years owned by me. I am currently building a home on 30acres so it was only right to purchase an ATV. For the past year before we broke ground I have used my 570 to pull a swisher trail mower, plow, heal wood etc. For the past 1.5 years it has been parked outside under a cover with bags of mothballs to keep out the mice. Would go to my property every weekend and it would start NO PROBLEM with never being on a tender or disconnecting battery. This year about 2 weeks ago I noticed it warned me of Low Voltage of 10.6VDC. and would not start with out jumping. I assumed the battery must be on its way out. I put i a new battery and it fired right up. After about 1 hour of Riding/Working I got the Low Voltage again. This time is died. Put it on the truck and dropped off at ATV repair shop. After a week of having it they said battery was dead, they recharged and found nothing wrong. I was told by them that Polaris's need to be on a battery tender when not in use because they have a constant discharge due to the fuel injector/pump. I don't understand how this is true if it started 1st try every weekend after sitting for 6 days through a Pennsylvania winter, never being plugged in to a tender. This is my first ATV so I'm not schooled on them, although I am a very mechanically inclined person. Anyway, I took it back up to my land and am having the same issue. What could it be that keeps draining this/these battery(s). The battery n it now is only 2 weeks old and it drains within an hour. I'm definitely not taking this back to the same shop. I bought a multimeter but need to teach myself how to use it. I've checked through the threads and have also learned that a lot of batteries sold are bad due to sitting on the shelf too long without charging.

HI Guys,
Just bought a 05 Predator 90, I seem to be having a few issues. Cleaned the carb today and now when the engine shuts off fuel drips from the overflow line until I shut off the flow. Nothing drips while the engine is running. I also changed out the plug, it seems to have been running very rich. There is still quite a bit of smoke coming from the muffler. It is definitely running better than it was but I think there is room for improvement. Any suggestions?

Greetings from central VA. Haven’t purchased my Polaris yet but planning on a 2018 Sportsman 1000 XP in March or April 2018. Hoping Polaris has some spring promotions and deals. I currently ride a Kingquad 400 ASI that just beats the heck out of me and the machine, while riding with friends on the Hatfield- McCoy trails. We do a spring and a fall trip. Rode a friends 1000 CanAm and it just floated over the rough trails. That’s when I was sold on a larger, better configured machine. Thanks for all the great advice I’m finding on this site. Stoked for next spring!

Went out for a drive today all of a sudden after i went through a decent size mud hole the hole was about 3 feet deep it was idling around 3700 rpm on its own what could my problem be

Hey all, I recently acquired a 2012 Outlander Max Unlimited 800R. A little
Background on the machine 718 miles, dealer serviced at 400miles. I called to verify, I also get my motorcycle serviced at the same dealer so I trust them.

The rear cylinder seems to be dead at times. At idle it is erratic. Every so often you can hear the cylinder fire and the exhaust pitch changes. The exhaust pipe on that cylinder is also warm to the touch after 10 minutes of idling.

I first started with verifying fuel pressure
KOEO= 51psi prime. Drops to 49psi
KOER= 51psi running.

I pulled the plug wire and put a spare plug into verify spark. Checks out
Engine sound does not change. I ran out of time to change the plug in the machine. I will do that tomorrow or next day.

Disconnected the fuel line to the injector. Connector was dirty. Maybe enough to get into the injector and clog the nozzle.

Disconnected the injector electric plug, bike went into limp mode. No engine pitch change. So we have power there.

Fuel tank is nice and clean.
Exhaust is free of obstructions

I know I should change the spark plug on that cylinder.

Should I look to the injector as the fault??

Looking for some advice on a budget friendly lift riding with my buddies and am having some issues bottoming out in some holes. See a lot of cheap lifts on ebay but none say they work on a 570 I know someone has found something. Also wouldn't mind some suggestions on tires was looking at some but it's hard to find a decent sized tire for a 12 wheel lookimg for at least a 28 since you can fit 30s stock

Hey guys, new to the forum and a new Polaris owner.
I just bought this 05 Sportsman 700 EFI. I'm having some issues with the idle running very rough. It constantly backfires from the air intake. Sounds almost like popcorn. Any help would be greatly appreciated. Currently I have a can of Sea Foam being run through it and have it idling out back. Bike had 500 hrs and 2k miles.Here is a video of it

Hi everyone: I would like to get more power, quicker take-off at the wheels. I just put 27" 8-ply tires which added some weight. What can I do in regards to gear change or is there another option. Thanks in advance for your assistance,
