Ok finally had time to get on with my bike , snapped the thread on the choke so can't start it
My cdi came without the powervalve set up, so have come to the conclusion that 100% is closed and 0% is open, there are so many settings I don't understand yet, but help appreciated :)
No so on mine I can have 8 different steps. Divide 2000 by 8 gives you the amount you need to increment it on each step. About 200 rpm for every step of the way till you reach completely open.
So not closed then 100 rpm later 100% open. Just a nice smooth line from fully closed to fully open using the steps as a guideline.
All bikes are different but it was just a nice guideline that let me set mine up properly.
Mine from borut is 200 closed and 640 open if thats any help. Im goin to check it though, the open position is easy but we dont have a mark or anything for closed. So im goin to take the pv cables off and get a good look at the servo to see how far it can turn then back off a tad.
