Good article, easier to follow than the shop manual, though I didn't learn much that I hadn't found out for myself by doing my 450. Nothing different in the 500 motor that I could see.
Apparently all ohc Hondas used the same camchain, I wonder what Trigger thinks about using a soft link on a CB750 rather than a continuous chain.
I used to devour Motorcycle Mechanics from cover to cover as a bike mad teenager, they once had an article on how to, for no expense whatsoever, get an extra gear on your RD250, just by removing a hardened stopper pin. After the police had examined a few accident scenes with a long black skid mark leading up them, they had another article telling you to put it back at once, as it was now possible, lost in your newly six speed gearbox, to change 'up' from top gear straight through into first!!!
