My first and favorite snowmachine was a 1980 Yamaha Enticer 340. Reliable, easy to start, fast enough for me, nimble, and fun to ride. In deep snow it would get stuck easily and unstuck almost as easily. I had the deluxe version with electric start (as if it were needed) and hand warmers that you could turn off. The only serious flaw was the indented headlight that would collect snow and dim the lights to the point I would have to stop and clean it out when riding at night in heavy snow. My neighbor had the Exciter 440 which was a much faster machine (I had it over 90mph on a smooth road) but the smaller sled was a better fit for the kind of riding that I used to enjoy. Now I am into skiing so much that I no longer even desire to own a sled but it was a lot of fun back then (in the 1980's).
