First time polaris owner from Alaska

Hey there everyone! I'm a first time polaris owner. I picked up a 2002 sportsman 700 real cheap. It has a few problems I was hoping to to see if y'all had any suggestions on what to do. The speedometer doesn't work and the 4x4 doesn't work. I figured at the price I got it for I could fix it and still come out on too. So if any one has any suggestions I would love to hear them before I take it in to polaris.
