I'm 72 years old, and haven't had a sled in over 40 years. A few years ago, I bought a pair of 1977 Polaris TX340's at an auction. They had been mistreated by the previous owner and needed a lot of TLC. This winter, I brought one into my shop and started to restore it. Right now, it still has the track in it, but that's about it. The engine had a mouse living in it, so I took it apart and am in the process of rebuilding it. I figure that everything that I do to this sled, I will have to do to its twin, so, when I order a part, I order two. By this time next year, I plan to have both sleds running, so that my kids and grand kids can use them. Oh yeah, I worked at a Polaris dealership from 1971 to 1976, so I kind of know what I'm doing.
