Default Calling all SBP Pipe users

Just wondering at what spped does your powerband kick in at. I have been cutting the "J" pipe down in an effort to tune it but I dont want to go too far. I guess I have chopped about 2" off it now and the band cuts in about 39km/h. Thats the powerband not going from 4 cycing to 2 cycling. I get to about 40km/h and it just wants to take off and startes reving real smooth. As its a 66cc my plan is to bring the band down to kick in at the lowest rpm possible.
Also I run a 36t sprocket.

So what size engine u got?
what size sprocket?
and what speed does your band kick in at?
