it would be pretty sweet if this article said how to adjust the clutch via the screws. tightening the screws get the clutch to engage at a higher rpm? or is it the other way around?

I agree, that kind of info would be really helpful here. I don't think I'm qualified to write about it, but I'll see if I can find someone who is and get them to write it. --Mycider 18:14, 11 July 2009 (EDT)
