Assuming that all the play shown is free and not against the PV governer spring, its sloppy and could use an adjustment. Remember this has nothing to do with free play in the flap/drums/rods, that is fixed by design and tolerances. This adjustment is like a reset to absolute zero position, at zero RPM. If its grossly off, like it was in my '03, the PV floats around rattling on the stop, and starts to open too soon.
Its like setting up a KTM PV after a top end R&R if you have ever done one, except there is no adjustable heim joint at the actuator, the bellcrank position/setscrew does the same thing.
Keep in mind that overall deck height effects this slightly. If your bike came with a big stack of base gaskets, and you removed all but one .3mm, the PV rod height in relation to the cyl in now higher and you will now have slightly more PV offset in the open direction. KTM makes a bigger deal about this and adjusting for it, but their PV is different. The GG PV is simple and tough, and its impossible for the main flap to hit the piston at any position. Perhaps the variable is from the factory setting the bellcrank position in the lower ends to a fixed spec, and then as they add top ends and various base gaskets to suit a desired compression level, the final overall PV starting position may not be absolute zero.
