How hard is it to drop a 450r engine into a 400ex frame and also about how much does one run from a private seller?
I am really interested in doing this but i need to know some pointers from people who have done it. How bad do i need to modify the frame and will i need a new subframe to mount the exhaust? Is there any kits made that make this easier and possible without sending the frame off?? Thanks, Kelley
