I don't think many flush the coolant. I know I don't, but then again I seem to have it apart every other year or so anyway.
Here is a procedure on PV's:
Power Valves
You may also want to do a search on Power Valves as there are a couple of ways to adjust them.

i have the yamaha service manual to see how they do it but it seems like someone told me that you dont have to pull the pv out but just take the outter screws(that screw into the pv and not the cyclinder) and by using a feeler gauge you can adjust by putting power to the servo's and when it sucks it in you measure the distance between the outer cap where it bolts back onto the pv. just wondering if anyone esle used that method.
You should pull them out and clean them and then adjust them. Maxdlx
