R6 engine conversion

I have an 04 R6 engine that I'm going to be putting into a quad. I have seen that most people that do this use a raptor 700 or 660 frame. I would appreciate any help with the pros and cons of each frame as to wich one would be the best to use. Or if anyone else has experience with this conversion into any other frames, would like to keep it all yamaha, but if there is something better I'm not opposed.

all I really know about this is the 660 frame is much easier to weld being a standard steel frame where the 700 would be more difficult because of the aluminum and other composite materials. However that might not factor in if its a direct fit. Other than that just look at engine and transmission mounting see how close it all is and make up some adapters. good luck post pics as you move thru this project I am curious.

From everything that I've read the only parts on the 700 frame that are aluminum are the sub frame and some of the suspension mounts, the main part of the frame is still steel. Can anyone confirm? I'm curious about the differences in amount of room for the engine and suspension geometry. The motor mounts are going to have to be custom fabed as the r6 engine basically mounts from the top and back. Looking for any other tips from anyone that has done a similar project.

the backbone of the 700 is aluminum. you could probably get away with just modifying the front half. my cousin has a se 660 with a fuel injected r6 motor in it that he wants to get rid of if your interested
