Jerky movement low gear high revs?

here is what the PCV adds to fuel mixture, fills in the gaps nicely.
0 is stock the higher numbers are % fuel increase at that RPM and throttle position.
or if you get an ECM flash but have them add the PCV increases would do the same thing, if they get the bike for the ECM flash and can setup on the Dyno, you can be SURE they will do % fuel increases like the PCV does.
