Ya, find in there where it describes using the air compressor to set the starwheel, that will give you a good starting point. As for the pre boost, I remember reading somewhere to screw it in until the nut is flush with the allen head, but that seemed like a lot when I did it. So many more mods and tuning to do, haven't changed it yet. Everytime you change the preboost, you have to readjust the star wheel after.

IMO Any changes to the pump is all based on your own matter of opinion. Like fuel plates, I know alot of guys who run a #100 plate with twins for towning. I know some guys like to pull the plate and foot out and others despise doing that.
As for your question if you dont know how to do it then look on the beginner's thread. And for asking how far to turn it. Like I said its all based on your opinion. un screw the cap for it turn it with a flat head. screw the b**ch back on and take it out for a drive, and see if you notice anything.
and adjust it as so from your results.
