NOTE: I miss-spoke in this video. Referring to the 1971 Arctic Cat inline 4 cylinder 2-stoke machine, I should have noted KING KAT as the model name, with its 789 cc Kawasaki engine.

In 1992, Yamaha set a tone in sled technology and launched the "Muscle Sled" era... Their new Vmax-4 was the most unique, most powerful, and largest displacement engine in a production trail sled. With 743cc from its four cylinders, the Vmax-4 was the power master for 1992. It was the first production sled with lightweight metal skis and plastic bottoms. It was the first production sled to use digital CDI ignition as well as multiple Mikuni TM flat side carburetors and rack throttle setup which gave an easy pull on the thumb.
Perhaps the most unique aspect was that the engine power was gear transferred from the center of the crankshaft to a separate jackshaft that carried the primary clutch. This reduced the torsional twisting of the crankshaft and kept the engine alive. The jackshaft runs at 90-95% of engine RPMs.
A well-maintained example of a first-year V-Max-4.
