Thanks for response got myself the correct dogbone and triangles, my next question is in relation to the ride height.
I have a vtr sidestand fitted which is obviously much better than the original, however when loaded up its still sitting too upright.
Can I extend the new shock by about 10 mm to improve this ?
Thanks
Sherlock

Just in case its of use to anyone, here is a link to the good supplier who made me a spring for my Ohlins when I was fitting a pre-load adjuster:

Time to resurrect a REALLY old thread. With regard to Falco Frank's post immediately previous, I've recently discovered who makes D Faulkner's springs for them; it's a company called Springcoil in Sheffield - only a couple of miles away from where I live.
I now use them for all my spring requirements and they are great; helpful and quick.
Last winter, after having visited John at Revs Racing, I decided to do something about the rear suspension on my red Falco. John had grabbed hold of the rear of the bike to test static sag and told me that there was way too much sag (something I'd suspected for a while). Going back through my notes and emails I realised that I'd specified a 700lbs/in spring for the Ohlins shock (on Falco linkages) with a free length of 150mm. When I measured the shock off the bike, the preloaded length was only 146mm which means only 4mm of preload had been applied, hence the soggyness that John instantly recognised.
As the shock has a hydraulic preload adjuster it would have been easy to increase the spring preload, but getting it to the required amount would probably have used up all the adjustment available. So I decided to order a 10mm longer spring (i.e 160mm free length) in the same rate (700 lbs/in) from Springcoil and see how that fared. As it happened, they supplied me with two springs for the price of one (due to a cock-up in their ordering system).
The spring was duly fitted to the shock months ago, but it's taken me this long to get round to riding the bike with the uprated spring (don't ask...) The difference was revelatory - night and day you might say. Before the bike was crashing through the stroke on big bumps and bouncing off the bump stop. Now I hardly notice the bumps - the bike just glides over them, even two-up. The bike has a poise and a degree of stability and unflapability (is that a word?) that I've never experienced before. It really was a Eureka! moment.
So if you weigh around 11 to 12 stone and are still using standard Falco linkages, then I can heartily recommend using a 700 lb/in spring with approximately 10% of free length as preload. I'm using 15mm (approx) preload on a spring with 160mm free length and the results are sensational. This is with an Ohlins shock revalved to suit Falco linkages, mind you. I wouldn't expect the same degree of excellence when using the standard blue spring Sachs (shudder...)
And if you need a 700 lb/in spring with 160mm free length, then I have a spare. £40 and it's yours. It's powder coated red, which may or may not suit your tastes, of course.

ok, it sounds as though it's going to be a lighter spring for me - I've 'filed' my notes from the last measurements I made, but I think the wire diameter is about 0.5mm less than the current Penske's so it could just be about right for me..
PM me with how you want to be paid and I'll sort it out tomorrow..
Cheers
Greg
