It was my bike that Richard re-timed, and it has made a big difference. The pinking has now gone, and the plugs are now a much darker coffee colour, so well done Richard. I would also like to mention another ignition related problem that I had experienced a while back. Different burn rates between the cylinders. One was always leaner that the other. Both cylinders now burn identically. The reason that this was happening turned out to be that not only was the cam ring worn, but also the the bearing in the points housing had worn off centre. I had initially fitted an anti-bias spacer that did effect a partial cure, but it was not the answer. What the anti-bias spacer did was to mask the symptom without effecting a lasting cure. If any of you are experiencing uneven burning between the cylinders check out the magneto that's where your problem will be. As a matter of interest my mag had been rebuilt and electrically it was perfect, but do not take it for granted the the mechanical tolerances are satisfactory. That had me stumped for quite a while. Mind you I am not mechanically minded, and that does not help either!
