Mickey,

Now that you mention it, I do remember reading something about an 800cc kit for the Prairies. I didn't know if it was still in the experamental stage or not. If it comes from you, I'm sure it will fly.

Polaris does have a way of coming out with some funky (read strange) motors. Still I'm wondering if the 783cc four stroke sled motor would bolt on. Granted, it is an EFI design but I believe it could be made to work. I believe it is a stroker mod, and not a bigger piston.
