Hey, I was just wondering if anyone has ever put a reasonably big (6-700cc) street bike engine in an older warrior (87). And if so did it work, and what size was it? Thanks for any info, I'm trying to get some ideas for this summer project. Oh yeah, one more thing, would the frame need strengthening/stiffening? Thanks for the help.

 

I saw a guy who put Ninja 600 motors in 2 Warriors. They sound really cool, and from what I understand, there was not much fabrication other than the lower frame bend and motor mounts. It has been a couple of years since I saw them out riding, so I can't get any more info.
