Will it work????

[fast_enough]

i know it would be a lot of work but could i bolt up a cr 500 motor to my 400 frame??? anyone done this??

yea ive seen it done. you can have it balanced and put more rubber mounts in there than imaginable but it will still shake your teeth out.

that will shake a lot

that will crack your frame if you don't put the motor on rubber mount
