‘The Cylinder head is from a 350 Matchless or AJS, also 50′s, which with its smallish valves gives high gas speed at low revs, which is why it pulls like a train. Point is no one valued 350cc bits and pieces 15 years ago – they all wanted 500cc stuff – so these bits were cheap and relatively plentiful. A “proper” 500 alloy competition engine was worth probably £ 1500 and I built the whole bike, everything, for less than £600 as I recall. And got, with the crank/piston relationship a full 500 anyway. The 85mm stroke flywheels make it rev like mad if you want. Ignition is a Chec PAL speedway bike magneto which I converted to manual timing control with my home made (about 20 attempts) back plate to carry the points. Very Trick.
Gearbox is a standard Burman type fitted to millions of 50′s road bikes, but with lightweight Norton clutch and shock absorber. Chain cases made from bits of Villiers cases all welded up by a pal of John’s who welds up nuclear subs. John welded up the oil tank from alloy too.
Back wheel from a 1956 James road bike with new rim, BSA brake back plate and linings. Severely modified and rebuild-able rear shock absorbers. Front forks from some 1970′s obscure British firm, possibly REH, with again my modified internals and damping, front wheel from auto-jumble. The Petrol tank is made for choppers in the 70′s with a lot of welding up.
