chains for sportsman 700

Hello all,
My machine is a 2004 sportsman 700 that I purchased in the summer for plowing use. I'd like to purchase low cost chains for it (amazon or ebay seems to have many for approx $55 shipped) but I'm not certain if my tires are stock/upgraded or who knows what as this is a used machine.

can anyone guide me how to proceed for correct sizing?
I see links like this one: and am wondering how and where to measure the amazon listing sizes of 54" x 14" etc theres 56x16 and so on ....

Please help me ID my quad!

Hello from Cleveland, OH!!! I just bought an older Polaris 350L 4x4 in need of work. I was told it was an early 90s, possibly but the guy didn't really know much about it himself. He said it was part of a trade deal and he just wanted it out of his garage. The price was right so I couldn't pass it up... the only problem is I know nothing about 4-wheelers! :) My friend is going to do most of the work but I'll like to at least find out the year and model for him.

So, first thing I'll like to do is find out the year so that I can print out the right wiring diagram for him. I'll like to have my buddy rebuild it the right way with all its lights and buttons in right working order. It also came with a plow/ newer winch set up so knowing that info really helps sort out the harness.
I did a little bit of research but couldn't come up with anything. However, I was able to locate a stamped serial # on the right side of the frame. ( 1770956 ) There's no model decal on it other than a 350L 4x4 decal and the Polaris one.

Any experts out there that can determine what year and possibly model it is by the number provided above? Any help is appreciated! Thanks! I'll try to post pics in the morning!

when to turn on AWD

I have a 2000 expedition 425. There is the AWD switch on the right handle bar. Do i have to come to a complete stop before i turn this on?

Buying just the foam for an air filter

I had a mouse get into my air filter and shred the foam in my 2017 Outlander 650 Max XT. The rest of the filter seems alright. Is there somewhere I can buy just the foam for a 707800371 filter. Wouldn't mind saving a few bucks if I could get the foam for $10 vs the entire filter for $50. Thanks in advance.

07 800 max cutting out

my 07 800 max cuts out sometime when I hammer it . It gets going then the throttle cut out for a second or two and the lights flicker for a bit . It had died once after starting and the speedo was dim. I have only run non ethanol fuel its got to be electrical .
