Model Help

I recently got an 04 sportsman 400 for my girlfriend to ride. It needs a little bit work and looking to buy original Polaris parts. Can someone tell me how i can figure out if it is the (A04CH42AA/AE/AG) model or the (A04CH42AQ/AR/AS/AT/AV) model. Any help is greatly appreciated!

Please help!!!

Rode last night everything was normal parked in the yard got home today turned the key on and nothing happens. Got my battery checked and it was good both post are as tight as possible. No power coming through any of the fuses but the key and it only has power going through two wires of the ignition when turned on

Greasing wheel bearings

Hey folks, I bought the tool from Machined Integrations for greasing wheel bearings. I would like like to grease my bearings while still on the bike. What is the best(easiest) method for doing this. I realize I need to pull the axles out of the bearings but have never done this. Hopefully I can just pull the bearing side out and not the whole axle. Thanks

used oem or new niche

The brakes were soft on my 2003 sportsman 500 and when I went to bleed the rear caliper I noticed that both bleed screws were sheered off. I didn't notice it when buying the atv a few weeks ago.

I tried to use an extractor to get the broken studs out, but the housing cracked and the caliper is ruined.

I can get used oem 03 caliper from a local parts guy for $80, but also found an ebay seller that has new niche ind rear calipers with pads for $50.

Not sure which one to buy.

Has anyone used the niche rear caliper?

I've read that their clutches are so-so and am wondering about their calipers.

Tires that are easier on the lawn and decent in snow

Yeah I know, ATVs and lawns don't mix.

Picked up a new 2018 base 570 with EPS and am now looking for new tires. Looking for something that's easier on the lawn compared to the Carlisle 489s but still offers good traction on packed snow and ice. I have very little interest in mudding. The vast majority of the machine's miles will be from using it for property maintenance.

My understanding for being easy on the lawn is a tire with a large and flat contact patch. For packed snow and ice, you want lots of blocks with siping.

I plan to move up one tire size across the board to 26x9-12 and 26x11-12.

Anyone have recommendations?


I've looked around a lot and have been eyeing the Sedona Buzzsaw RT shown below. Can't find anything on this site for these tires. Thoughts???

First thoughts of 2018 Outlander Max xt-1000

So I just got the bike on Saturday, have put about 20 miles on it just riding in my yard and a couple runs up the road, when I first put the green key in I thought it was good for my wife or my 14yr to ride on, put I ran it around the woods a little bit myself on the green key, what a dog, it does go 46, but it almost feels like its running on 1 cylinder, I have a 16 sportsman 570 and it would smoke this 1000 with the green key.

My neighbors 16 xt-850 has a grey and black key, it feels the same performance wise on both keys, just limits speed. At this point I really don't see a performance advantage over the 850, honestly it may feel a little slower, I guess my machine may need a little more break in time and it is a little heavier, but its supposed to be 14 more hp, I think his is rated at 75hp, we will have to do a drag race soon.

I do like the ride quality better than my Polaris, however the engine breaking is a little aggressive, I went down a small incline and was off the throttle and the rear tires locked up, I prefer how the Polaris acts going down a hill it will roll until you bump the throttle then it will slow down but not lock up the tires, definitely surprised me.
