72 cheetah 400 - my first Arctic cat. Sold it in high school after replacing motor mounts several time (jumping the snowbanks in the driveway). Chaincase was wrecked when I sold it, I didn't have the money for new chain. Wish I would have kept it around.
I bought a 1972 Cheetah in about 1982. It was a 440 Kawasaki. I took the cylinders off the motor and polished the exhaust ports like a mirror....put in new pistons and rings. I also added a Mikuni slide carb...It would pull the ski's for what seamed like a 1000 feet....Im sure at 50 mph....But I was impressed...:wacko:
