More bad news for the APE clutch:

"Somewhere around 76 Honda changed the clutch assembly, adding a double thickness riveted steel plate in the center of the clutch sandwhich.  The entire depth of the clutch package was increased.  The outer most friction disc also had a wider tang that mated with a wider slot in the outermost portion of the basket.  If your clutch is this later type then your "69-78 kit" will probably not work correctly as it is probably designed for the earlier clutch.  I ran into this problem with APE's extra plate performance clutch when I tried to use it on my 78ks clutch.  Make sure that you examine you clutch parts carefully and compare the stock pieces to the Barnett setup. . . . .From what I have read, Honda used stronger springs (don't know about length) in the F2/F3 clutches to keep things from slipping with the higher powered engine.  Clutch springs aren't particularly expensive and I have had good luck with heavier springs that came with the APE kit (the only part of the kit that I could use).  Perhaps you should just buy a set of heavy duty springs and not worry about the wear limits of the stock ones??
