Very detailed report, Graham. I was using the similar methodology, i.e. the ratio of clicks (rear) and turns (front forks). Mind you, the stock suspensions wear rather quickly IMHO. For example, I was also on 4/9 and 12/27 10,000km ago. Now I'm at 7/9 and 21/27 now at 18,000km. And the majority of the past 10,000km is on empty stock sidecases and I weigh around 73-75kg including gears, and I ride 95% onroad. What I am trying to say is the stock suspension is rapidly approaching the end of its life.
