YZ426 frame ?

[miles Machine]

Im buying a yz426 frame but my buddy has a z400 engine that has been bore to a 450 with hotcams, i was just wondering if it would possibly fit the frame with minor mods or would it be something extensive.
if ne one knows ne thing about it the info would be appreciated
THANX

Yes it would fit. You would have to make all new mounts. A yz motor will walk all over a the suziki motor all day.
