I'd say the other thing holding the Morini back is the cost. Speaking of small motorcycle engines, it's much cheaper to build with a Cub/Super Cub engine or clone. The industrial/commercial engines most of us 4-stroke guys are using may be unsophisticated, but they're cheap and they work very well!
All I hear is Cheap Cheap Cheap.
Cheap and racing don't go hand and hand unless you enjoy being in the back of the pack.
