With the Pulse, even though the throttle response was a little 'soft' on the bottom end (compared to my DUO 4.5), the throttle curve and powerband was much smoother. It would be a much more 'driveable' motor on a low-to-medium bite track (vs. a DUO, which feels as if it has a much shorter powerband).

I have been running the Pulse 4.5 118/22 with 8-10 degrees of timing, rubber tires on indoor, high bite surface. My motor is finishing at about 165-175 degrees (in 65 degree ambient temperature).
