[QUOTE="timetraveller, post: 47700, member: 456"] If you want some of the short springs I still have two left. One is the 'red', 75lb/inch, intended for use Comets but which turned out to be too weak for fully equipped road going Comets. The other is a 'white', 130lbs/inch intended for use on heavily ladened twins or outfits. Experience by several riders has now shown that a combination of these two springs, giving a combined mean rate of 102.5lbs/inch per spring, is about right for most twins. This is slightly weaker than the 'blue' springs which were also part of the original batch, which had a rate of 110lbs/inch. I have one outstanding order so a new batch of springs will be ordered this winter. These will have a rate of about 105lbs/inch and also some more 'white' springs will be ordered for the heavier bikes. If anyone out there would like to place an order then their request will be incorporated into the order. Price is expected to stay about the same as the first batch at £15 per spring. Coincidentally I have also been working on a simple system to incorporate a method for adjusting the spring preload which would be just about invisible but other projects have got in the way of final design and prototype manufacture. Noting that these springs are all approximately 100lbs/inch then it can be seen that an adjustment of only one inch can give an adjustable preload of 100 lbs.
