400ex yamy hybrid????

[sburton1]

hey guys seen lots of guys droping in 450r motors in their 400exs. has any one put in a yfz450 motor in one NOT the yz450 motor cause ive got a good deal on a yfz450 motor and was wondering if its to much harder than the 450r conversion. as far as motors i know the yfz is way better but dident know if it would fit. i know you kned to make up some motor mounts but has any one done it and posted some pics??? thanks guys

don't know who's done it. know it is doable. seen pics of yz400 motors in 400ex's before so i'm sure it can be done. here, there is a pic of a yz400 in a 400ex chassis. http://www.exriders.com/vbb/showthread.php?s=&postid=2328478#post2328478ne.
