There are already a couple of 980cc Buell Blasts running around, it's using parts from 112 Cu/in V-twin.
With a balancer (?) it should vibrate less than a twin (maybe?)
I still don't really see 100bhp from it though, just cant spin it fast enough, around 7,000rpm the big end disintegrates, more boost, pistons melt down.
It can be done, but engine life won't be too great
