He was 19 to my 35, a gap of 16 years, or of Geological Time for a young man. He worked for me as a carpenter when I built timber framed buildings, and he rode 'bikes with a passion'. There I was, fiddling with the carb balance on my '73 Triumph T100R Daytona (still the fastest production 500 made in the UK), he with a sandwich in one hand, cigarette in the other. "Why do you bother with such an old 'bike when Jap kit is so much more reliable?" he asked, clearly unaware of the emotion which his question stirred in an old man. I stood up slowly, trying in my turn to understand how little he understood the connection between earlier generations and their beautifully flawed machines.
