Is there any official word in how Honda/Montesa is achieving the "Less Engine Braking Effect" in the 2014?

Is it by the cam's, electronically, a valve, etc?

I think it would be fairly simple, yet I am not sure if their mapping normally does a total injector kill on decel like we would do in a car, but if so all one would need to do is bring them back into play a bit sooner.

With EFI stuff it's pretty easy, idle speed controller just brings it to idle slower

I'm not sure how Hondas system is made but that's how it's done on other systems

Even a heavier crank would do it

all of the press material specifically calls out a crankcase decomp system so doesnt sound like efi tricks.
