1926 AJS 498cc Model G8 'Big Port' Project
Registration no. YB 4641
Frame no. 86150
Engine no. 86150

After victory in the 1920 Junior TT, and in the Junior and Senior events the following year, the new overhead-valve AJS made its production debut in November 1922. Originally built only as a '350' - latterly known as the 'Big Port' - the ohv AJS became available as a '500' for the first time in 1926. Coded 'G8', the new 3½hp model followed the lines of its successful smaller sibling. The engine combined the latter's 90mm stroke with an 84mm bore, distinguishing itself in the 1926 Isle of Man Senior TT when AJS works rider Jimmy Simpson became the first man to lap at over 70mph. First registered on 4th January 1926, this early example of the rarer, '500' Big Port comes with a continuation buff logbook stamped by Somerset County Council from 1946 onwards. The vendor's father purchased 'YB 4641' at a York auction in August 1947, it is believed for £40. Brought back from the auction and stored in a coach house, the machine has not been touched since then (the engine turns over). It appears to be very original and almost complete, the most obvious omission being the oil pump, while the magneto was found on a nearby shelf and is included in the sale. An exciting project for the 'Vintagent', the machine comes with a current V5C document and is sold strictly as viewed.
