Hello to all my cousins across the pond!
I'm a new user from Texas, registering in both SOHC forums -- looking now for advice and information for my 1974 CB750K, which looks nothing like original and has been a source of much gratifying repair work. Thank y'all for all the great anecdotes and instructions you post - your wisdom will be (and already has become) a most valuable resource for this clueless mechanic.
All the best.
