Thanks to Andrew for his kind comments and the feedback. This helps other riders to optimise the combination of dampers and springs which will give them the best results. On that front I recently heard from Robin Stafford who rides a twin. He weighs about 13 stones (182 lbs, 83 kgs). I thought that the 36 lbs/inch springs and the normal AVO front damper might be the best combination for him but he found it too stiff. I therefore sent him a pair of 33 lbs/inch springs which he found just marginally too soft. His experimental solution was to take a pair of the original small diameter Vincent inner springs and cut them down in length so that they only came into play when the forks had been compressed about 1.5 inches (3.8 mm). He finds this to be a very comfortable and well handling combination. The softer springs respond quickly and easily to small bumps or road imperfections but with large holes, traffic calming bumps or heavy braking the stiffer springs come into play and imperceptibly take up the strain. I have checked with the spring manufacturers and there would be no problem making some of these and they would be wound in the opposite direction to the outers to avoid coil binding. As Robin shortened his springs the spring rate will now have gone up so it would be good to find out what the spring rate is now.
