I read 2007 Arctic Cat 650 H1 4x4 Automatic has a single-cylinder, liquid-cooled 641cc engine.

Who makes the engines in these and are they any good?

i believe that was the first year a/c started using their own motor. my cousin has an 07 650 h1 and it makes a lot of power. smooth strong pulling power, even for an auto.
