Sorry but,
 

I would love to see variable cylinder management on bikes.

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.

Uhm... what's BFE? :scared:

Mire stuff that can break silly

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

Butt fuck egypt. Its a general term for the middle of nowhere

:lol:

Ah... got it.

Or bum fuck egypt depending on your local dialect...

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.
