Won't happen unless you start seeing 6 or 8 cylinder engines.

The fuel needs to be cut anytime the bike is an a decel regardless of engine temperature.

Simpler = better in that department IMHO. More stuff = more to break when in the middle of BFE.

More stuff to break? It's just the ecm turning off the injectors. The pistons are still moving.

Not that simple. It also deactivates the valves on the dead cylinders. If you let the valves keep opening, you're pumping air with those cylinders and creating more power loss.

I'd just be happy to have a motorcycle that is made without California in mind. How about a 1000cc 2stroke sportbike???

How much more could a bike benefit from that? My old 96 CBR600 (non-cali model) gets around 45mpg with hard use in the mountains.

No smokers, but these guys seem to have the right idea at least for enduro bikes:

950cc liquid cooled v-twin... in a 320lb dirtbike IIRC...

A "Jake-Brake" for motorcycles (only not... and yes, I understand it's not the same thing but humor me)
