I am looking at a 1000 outlander a guy has on Craigslist. He knows me a little so he's letting me look it over before making an offer. Before I look at things under the plastic, can I get opinions of what it could be. I thought it was the transmission and if so, not interested. Basically when you crank it up and put it in gear, if you hit gas too early it grinds the gears. After you wait and hit the gas, the atv shakes like you are riding through a earthquake. After you pick up a little speed, it smooths out n rides fine. If it's something cheap to fix, might be a good buy. Clutch, belt, transmission? Any suggestions?
