I'll admit to just skimming the posts, but did you ever try changing the oil? I tried using some 15W-40 (I have a 60 gal. bulk tank and use it in all my tractors and cars) in my Goldwing, and the clutch started slipping any time I got it over 3K RPM's. I changed it out for some '4T' motorcycle oil and it went right back to normal. Possible the previous owner put in some automotive oil?
