Gentlemen, Happy New year to all.
I`ve read on the www there is supposedly someone making & selling a finned aluminum cooling ring to fit to the brake drum when ie using the dual cam brake setup offered. Those rings where offered as an option to later model Panheads and I see them on e-bay from time to time. They dont fit the earlier drums as later pan drums where one inch wider than the WL ones.
Any hints would be truly apprechiated.
