[QUOTE="timetraveller, post: 98009, member: 456"] Remember that I have 30 lbs/inch springs made and in stock. The 36s, 33s, and 30s are all supplied to be fitted with 3" of pre-load and this can be reduced by reducing the length of the spring as Greg has done. The 3" of pre-load was a figure arrived at to give the correct lower link angle with typical weights of bikes and riders. If weaker springs are required then there is no problem getting them made but there has to be a compromise between weak springs and the correct ride height. Feedback is required from several people to arrive at an acceptable compromise. The springs only cost £30 a pair so it is not too expensive to experiment. The stiffer AVO dampers were required with a heavy rider on a twin with the Greg mod. If they are not required on a single with a normal weight or light rider then, if you have bought one of the stiffer ones, AVO will modify it and if not then perhaps the standard AVO will suit you. Most recent feedback from the Tilleys suggest for touring on their twin, two up, the stiffer AVO damper together with Greg's mod and 36 lbs/inch springs is working well. [/QUOTE]
