Like a 1983 CB1000 Custom Honda. Too bad the V-4 replaced it but progress must happen I guess. You know water cooling, self adjusting valves all came in 25 years ago. It does exactly that. Kick it down its 2 teeth taller, kick it up its for low end torque. Not that it needs it. Does 115 MPH in 3rd and will burn rubber out of the hole.
