As a new to mx 2 strokes I notice that the bikes exhaust port opening times are an average 10-15 degress earlier than a saw. I know that they have power valves to change the timing at rpms, but why can't a saw get away with 84 deg vs 98-101 on a saw. I have been reading the two stoke tuners literature seaching for a comparison and a hint into why. Stock motos a make power at 7-8k rpm. Stock saw power at 8-10k. It is the giant time and duration on the motocross bike that does it?
