[QUOTE="High Lord Gomer, post: 121958, member: 16469"] PLEASE do not attempt to answer questions as an expert if you do not really know the answer! If you plot horsepower and RPM on a graph, the "powerband" is the range of RPMs during which optimum power is made. It is used to describe a range of RPMs. It is not a physical object that can be touched. On most 125s, it is fairly high in the RPM range. The powervalve opening to effectively raise the exhaust port does not "make" a powerband. For a better understanding of all of this, I would suggest searching on: Powervalve, PV, and powerband in both the advanced tech and Engine Modification forums. [/QUOTE]
