hey all need some help and opinions on sleds, the last sled i had was an 88 exciter and i dont know much about any of the newer models. currently i am looking at a 95 mach z w/ 800mi in the local want ads. it has a crankshop motor with 600 mi on it and crankshop pipes, plastic skis, brand new track with 196 studs, all new shocks. all for $2500. i know this is a pretty good deal. what should i look out for and are these sleds problematic? what about the 96-98 mxz's? how are those? any input would be greatly appreciated.
