chuckie, correctomundo. when i recently checked and set mine, fully open
was completely recessed into the cyl. (they swung open towards the head).

the markings on the brackets is crap. neither motors i have had were very close to mark. i used a sharpie pen as a reference when i had set them long ago. worked ok. i think hi on the servo was open.

i ought to have a talk with matt p. 'bout this. i noticed that the valves opened
up early in the revs (6-8K?) 125s don't run power valves. how 'bout welding
'em up all nice and smooth. how you fancy that? "we don't need no steenking mid-range!"
