changing the port timing will change the rpm range where the saw makes power.  Generally, the more duration the higher the peak rpm/power levels.  Timing (duration open) and port area requirements need to be met to produce a given level of power. you can change the aree, i.e widen ports, to a point to achieve the desired results, but ultimately the duration will have to be increased as the port width jeopardizes ring life after a certain point.
