hello, i have a couple of questions about the trail boss 250. i am looking at a 1988 tb 250. i can buy this machine for $375, it has a few problems. it needs to have the top end done (bore piston etc.) i am interested in this for my wife. are these reliable? brakes good? can i get parts for it? it is 2 wheel drive . i remember these when they came out new(around 88) and they seemed pretty nice, how did they hold up overthe years? am i better off getting a mojave?
