I just purchased an '88 Big bear 4x4. I have always had sport quads and this is my first old timers quad(pushin 30 now)..LOL. I am planning on using this to plow my driveway in the winter, and just for normal screwing around. I am wondering what stuff I should look at, and what normally wears out on these quads? The top end of the motor looks the same as my wife's Warrior, is it? I don't want to make this faster, I still have a 250r to go fast on, just want to make it reliable. Any advise will be appreciated...Thanks
