I got news for you, suzuki does if fact make the drive train for the ac's, In fact suzuki owns 33% of ac.

 

I was wondering the same thing about the 400. I am thinking about buying the 300 just because I can shift from 2WD to 4WD. I like that feature. However I would love to have the Liquid cooled motor of the 400. If anyone finds out about the ability to make this change please let me know.
Thanks,

 

do you think adjusting of the lever work on a 2003 arctic cat 500i ?
