Do you happen to recall the powervalve setting on the Beta?
I find a very noticeable difference on mine when playing with that screw.
I can easily notice 1/2 of a turn.
With 3.5 available turns of adjustment, the bikes go from fast revving to lug with the simple spin of a 5mm allen key.
Turned all the way in, it feels like a baby 300. Flush with the case it feels like a 150 with some more bottom end.
I never looked at the PV setting. It was a friends bike and I rode it up some hills for him on a couple rides.
