Well for the price its going to cost you to push 30hp out of a 420 . You might as well drop a nice 250cc bike engine in there.
Also you can only build the motor so far until it just becomes un-practical to put it under everyday off-road use.
All of those "50-60hp" are only ran a few times then put in for rebuild. and even at 30 which that i do believe it could produce. your cost for build is going to be up there.
