I was just tearing down a spare 1147 I had picked up several months ago, and
found some very interesting things. The head had been ported, oversized
valves installed with seals. (1300 & non-triumph valves) Head has also been
shaved. There is the porters name, and either the flow or chamber volume
scribed on the head. "H. Lyness 69 33cc." Any history or information on
this porter would interesting to know. He sure did a nice job on the head.
