Cooling Method:
Air-cooled, as is typical for motorcycles of this era.
Racing Engines:
Specific manuals and sheets for racing models like the AJS 7R feature OHC configurations and high-performance tuning details.
Typical Intervals:
Highly variable by model and use. Basic checks like chain lubrication and brake adjustment were often daily/weekly tasks. Engine servicing varied greatly, potentially every few thousand miles for major overhauls.
Engine Oil:
Typically SAE 20W/50 or SAE 30 monograde oils for engines with separate gearboxes. For pre-unit construction, gearbox oil might be separate and specified. Consult specific manuals for exact grades.
Gearbox Oil:
EP (Extreme Pressure) gear oils for some gearboxes, or specific motorcycle gearbox oils. Capacities typically around 1 pint (0.5 liters).
Brake Fluid:
For models with hydraulic brakes (later 1950s onwards), DOT 3 or DOT 4 brake fluid would be specified. Earlier models used mechanical actuation.
Common Wear Items:
Valve guides, piston rings, primary drive chains, clutch plates, magneto wear, electrical component reliability, frame fatigue in high-stress areas.
Maintenance Focus:
Regular lubrication, decarbonization, and careful adjustment of mechanical components are critical for longevity.
Carburetor Tuning Challenges:
Setting up vintage carburetors for smooth idling and acceleration can be temperamental. Manuals provide guidance on float levels, jet sizes, and needle positions.
