I have a service manual and the original owners manual for these bikes in PDF form. Included are simple adjustment instructions for the clutch. I can e-mail the files to you if you like. The clutch does need adjustment occasionally, and it can take a few tries to get it right.
Oh ya- just to let everyone know, I paid sum total $300 for my Hondas. The yellow one was given to me by a friend in SF and I bought the blue one from some folks in Napa. Both run very well.
