  1. R6 engine in a 660

    Yamaha YFM660R Raptor (2001-2005)
    Hey guys it's been a while. I'm going to be putting a 1999 R6 motor into my 2002 Raptor 660 frame. I don't want to hear form nay sayers, b/c It's gonna happen, whatever it takes. Anyways, I was wondering if anybody has done this conversion. if they have any pictures, pointers, fabrication...
