polaris 700 sportsman or ranger short block.
 

O.K. here is the next question in my quest to repair my motor, does anyone know of a place that sells short blocks for these things. i'm really trying not to spend all of my kids collage fund fixing this thing but i'm at whits end. and am really looking for the best alternative to not have to spend 1500 in new and used parts.

Thanks for any help.
