First of all what exactly does a powervalve do? I'm pretty sure it smoothes out the powerband, right?
Second, when were they introduced? I know that 80's didnt have them until 1999 or so. What about 125's and 250's?
I am asking this because I am thinking about buying an older model (mid 90's) 125, and don't know if a bike with a powervalve will be any different from a bike without one. Any help would be appreciated.
