no.. porting is the permanent removal of material from the jug/head ports to increase airflow to improve performance... changing the size of an exhaust port while the engine is running is a powervalve...

Ok now I get it. So how do the "powervalves" open and close? Is it on the fly like with the trottle or is it controlled by the driver?

Yeah. I thought it was a good idea, considering the other cylinders with powervalves are the fmf and the trex and they cost around $2000. I figured that I would go the cheap route and see what the results were.
