Ironhead clutches are notoriously pernickety to adjust. The line between drag and slip is a very fine one and you'll get plenty of practice before you get it right.I run a 72 myself but I'm not sure if the adjustment's the same procedure as of course mine has the wet clutch.
Best bet is to send a PM to
the french owl on here; Patrick runs early Ironheads himself and what he don't know about them ain't worth knowing.
I suggest you invest in a large quantity of patience though!
One consolation; once you get them right they do tend to stay right!
