THE FAMOUS JAMES No. B4 350 c.c. O.H.V. SUPER-SPORTS DE LUXE MODEL

The specification of the 350 c.c. O.H.V, is complete in every detail. The power unit is particularly well designed and proportioned. The valve gear is light and durable, large bearings eliminating wear on the overhead rockers. The cylinder head is hemispherical, and the valve ports are of correct design and are well finned. The piston is a special aluminium alloy of great strength and lightness. Valves are of large diameter, and are machined from special alloy of nickel steel which will withstand a high temperature without deterioration. It is a unit that may be depended upon to stand up to the extreme conditions demanded of such a fast machine.
