1927 AJS MODEL H4
AJS built a fine line of motorcycles in the late 1920s, including side-valve (SV) and overhead valve (OHV) singles ranging in engine size and output. Horsepower was in the single digits across the board. The H4 was a 350cc SV single with advanced features for the day. Special alloys were used on critical internal parts like the valves (intake & exhaust valves were interchangeable), gears and so forth. The Binks carburetor was considered ‘semi-automatic’ and was said to provide “fierce acceleration”, all from 3-1/2 horsepower. The 3-speed gearbox was hand-shifted from the right side of the tank. It had a bicycle-style diamond frame with flat tank and rigid rear section. The front forks were girder-styled with shock absorbers.

Hi, I have a 1927 AJS 350 Big Port motorcycle. I am looking for detailed literature on the technical operation of the engine and transmission.
Do you know where I could possibly obtain this?
Thanks, Grahame.
