What do you want to know? Here are some starter specs/facts. I believe they stopped making them in 1987. They were originally equipped with a Kohler single cylinder,2 stroke, 20 HP motor. They have TWO (Tempermental) transmissions that were made by Vesely, and are also no-longer made. They take straight 30W motor oil. It can turn around in it's own tracks, making it a "Zero-Turn" radius. (I believe that this is the only ATV that did/does, but I may be wrong) It weighs about 675 lbs (With original engine). It is amphibious (Of course). And it will take a 45 degree incline. The keys to driving it and having it perform as you would expect are: 1; Make sure the trannys are properly adjusted, 2; maintain constant 1/2-3/4+ throttle while driving. It is a blast to drive! Biggest drawback is that it only has 6.75 inch of ground clearance. (With stock size tires) Watching/knowing your terrain will really help in preventing you from getting stuck/high-centering.
It's all just nuts and bolts.
