The SOHC Hondas were indeed 2 valves per cylinder. It was Yamaha that started the more valves thing, and wound up with their 5 valve "Genesis" engine, then went back to 4 valves. Most performance engines have 4 valves per cylinder, while a non performance engine makes do just fine with 2. I'm hoping the CB1100 is tuned more for low end torque than high rpm power, which comes on so high up the rev range it is pretty much unusable on the street. SOHC 2 valves per cylinder and 1100cc should put out plenty of power for a standard (non sport) bike. And you would think the FI should take care of any emissions issues.
