I hear this term frequently in trends and was wonder what the term meant. I assume it has something to do with modifying the chaincase or drive/track. Thanks for the info. Merry christmas!!
That's right, it means to drop the chain-case down etc, to fit a bigger driver in, or bigger lugs on your track if you don't have enough room. My 98 Polaris 700 has been dropped and rolled, and had 10 tooth drivers in there now.
