Hiya, Newb here. I just acquired a Polaris 400 4x4 liquid cooled 2 stroke quad. I cant find a VIN on the frame but I did find a tag in the right side wheel well with a serial number on it. If Im reading properly here this is how they Identified them prior to stamping the VIN on the frame. Is this Correct? the Number is : W948140. Again from other posts I assume this means its a 1994 quad. It was a friend of mines quad that died 5 years ago. His brother took it & just left it sitting next to his garage for the last 4 years. He called me out of the blue the other week & said if I wanted it to come over & take it so I did. Got it started & on the truck but boy was it smokin. With a little TLC i should have a decent machine.He did say something about when he did have it going the oil light would keep coming on. Anny ways any help you can provide will be appreciated.
