I have a 1951 C Rapide and would like to time the valves with a degree wheel. I can only assume the bike has the original cam lobes but have not pulled them yet. I have read about the Mk 1, 2 and 3 cams and would like to know how I can tell which ones I might have, as the timing appears to vary with each. Are they stamped? Alternatively, are the cam measurements published somewhere which will allow me to identify mine, please?
TIA,
Paul.
