Ignition is by Joe Hunt Magneto, there is no other wiring on the bikeso no need to keep the alternator.

The Tr6 motor had lost compression on its last run out. A top end strip down revealed badly worn bores and a broken valve spring. A Morgo 750cc big bore kit was ordered and fitted, and the valve springs replaced with some spares from the shed.
