| Tim the standard SS shock is 328mm between fixing centres, one end fits directly to the frame just under the rear of the tank the other end bolts directly to the A frame part of the swingarm as it is a basic cantilever set up.
Each end of the shock has a eye fitting that are unadjustable, as the rear shock to wheel travel is approximately 1.9 to 1 then a shock length of about 235 to 240mm should do the job. With the standard shock at 328mm then there is not enough room between fixing centers to fit a proper adapter. I have thought about modifying one of the shock mounting points, the frame one seems the obvious one to do, where as the swing arm one is easier to take to my local fabricator and have him sort some thing, either of which I would first have to run by the comittee to see if it is within the rules.
My other choice is to use a shorter shock and a adapter/adjuster. I have a 290mm Paioli which woul give me 45 to 50 mm of space to fit an adjustable adapter in. As the shock only owes me £65 this is still a very cheap option and inside my budget, failing that I have an adjustable Penske that I'm sure I can get a mate to modify for me to get the right length, currently on its longest setting it is 320mm so basically I just need the adjuster bit to be 20mm longer, not to much of a problem to get made but as the shock is worth £250 plus then the budget is getting eaten up.
