Supercharged
The rear cylinder cut out on the Harley's is nothing new. It has been offered on the Police specials for years known as the parade mode. At idle the rear cylinder will shut down, Touch the throttle and it immediately kicks back on. Very good sense when you consider the design of the bike and how much hotter the back cylinder runs as compared to the front cylinder.
They can call it whatever they want, but it's actually just a band-aid for a poor engine design...make the engine liquid cooled and the problem is solved, but Harley refuses to come out of the stone age....
