Pretty well summed up.
In my opinion, no more V2 cruiser stuff for God´s sake. Its covered by betters already. And think E-H. Failed due to the limited vision: Hey guys why don´t we do another run of the mill V2 engine, it´s gonna take the market like a storm! One-and-half litres pushrod V2 class, already so overly occupied by much more capable and established (one more established than the others) players. Had they started with, say 2000 cc or something, with balancing shafts, it might have gone somewhere. But now even that segment is occupied. Only way to go is, like has been suggested, extended Rocket 3, that is inline 4 with water cooling. That is the only way.
And what it needs is a dedicated guy with deep pockets, cow´s nerves, elephant´s patience, and a big focus on *performance* and quality. When I say performance I don´t mean canyon carving ability or any of that wussie pansy stopping-distance stuff but straight line pure acceleration power. I mean big power and torque. Did I say deep pockets? It can be done (again: Triumph).
What it does not need is some loser beliving overly optimistic sales forecasts and deciding to take it to the wire getting rich at the end. He´ll just talk to those investor friends to chip in a bit to fill these gaps, hey the very real power point slides are there to show the projected cash flows.
