hello, its my first year riding and i currently have a 1990 yamaha PZ480 witha 136 track. its very light and easy to toss around, but there is no power. all i ride up here in B.C. is powder so i am looking for a little bigger sled with a longer track.Im kinda a little guy(only about 170 pounds if im lucky) so i dont want a tank of a sled either. I was thinking some where between 1998 and 2004 just becuz of price. If you have any advice for my that would be awesome, thanks
