I have a 93 model 2X4 2 stroke Polaris ATV I've had here on the farm or 10 years. I had a problem with really hard starting and had a shop check it over and found a broken piston skirt, and a piece of it apparently got in the bottom end and made a small crack in the crankcase. I took it home and may take it apart myself sometime. Anyway, I've come across 2 Explorer 400 4X4's and a Sportsman 500, all '96 models for sale reasonably close to me for about the same price. Any advice as far as which to buy? I've heard the early 500's had electrical issues. I will be putting a sprayer on it off my 350, so it will be pulling on the battery some. The 400's run chain drive front and rear and a solid rear axle, the 500 shaft drive and independent suspension. What would you guys suggest, trying to keep it under $2000. Thanks! I've driven all of them, and the 400's will out run the 500's no problem, and I think my 350 would too.
