I am a bit confussed. I went back and loosened the bean can and started the bike again then rotated it anti clockwize with the strobe light on it checked it again at all the way back the the ideling was higher and the "Z" was in line with the grove on the casting.
On turning the bean can clockwize again the "Z" moved downwards but the "S or ---" could not be seen and the ideling dropped.
Remenber when I first looked at it the bike was difficult to start and the "Z" was lined with the mark.
So with the bean can fully rotated clockwize the bike starts easy and the ideling is lower.
