[QUOTE="Albervin, post: 17791, member: 586"] I have discovered a wide variation in distance between centres of spring units & dampers. It is important you match both the extended & compressed lengths of the combination you have otherwise there will be some serious banging of metal. It is also important how you mount your springs/damper. For instance, you can have the bike on a "D" type stand or the original rear stand. This will make a huge difference in how you fit your suspension. On a "D" type stand the suspension is fitted at the extreme of extension & this should be just less than the extreme extension of the damper. Be aware that the SP4s should be screwed in at least 3 threads to hold the plot together. When using the rear stand you can adjust the suspension by using a jack under the cases but you still need to be aware of where the compression & extension limits are. Some dampers can be used with a bump stop rubber & others cannot. You can tell if you need one by the "clang" you hear !!! [/QUOTE]
