How to restore: Honda SOHC Fours - CB350, 400, 500, 550, 650 & 750 SOHC Fours (1969-1982) (Enthusiast's Restoration Manual)

In 1969 Honda launched a motorcycle that many consider to be the world's first super bike. The Honda CB750 had the first mass-produced 4 cylinder inline engine, a single overhead camshaft, 4 carburettors, a 4 into 4 exhaust system and came with electric start and front disc brakes as standard.
This specification set the bar higher than had been seen before on a production motorcycle and lead to the other Japanese motorcycle manufacturers introducing their own 4 cylinder motorcycles, albeit some time later.

Following the success for the original CB750 Honda went on to produce a range of motorcycles using SOHC 4 cylinder engines. All with their own characteristics, they proved to be reliable and smooth running and even today can offer real reliable transport on modern roads if restored correctly.
Now with some examples over 50 years old many enthusiasts wish to restore these classic machines.

This guide has been written to guide the enthusiast through his or her restoration of these fine classic motorcycles. It covers dismantling the motorcycle and its components, restoring and sourcing parts, paint spraying, decals and polishing.
The chapters cover engine, frame, forks, fuel, exhaust, seat, brakes, tyres, electrics, up to the rebuild and on to safe setup and general maintenance and finally onto riding safely and storage.

Covers the period 1969-1982, and models CB350/4, CB400/4, CB500/4, CB550/4, CB650/4 and CB750/4.
