Post script.......

Just been out for a blast on the GS, blown some cobwebs out my head and remembered something else regards the initial question.

The first lowering links I tried were the "multi position" ones from Projection Components. These ones http://www.projection-components.co....model-88-p.asp

My experience of them was that with the genuine Yamaha centre stand fitted these links did not work. The link fouled the left hand mounting bolt on the centre stand. Not in every position (there are four height settings) but in two out of the four they hit the bolt and this was enough to make me send them back for a refund.

I do not see this as an overall problem with Projection Components products, just this particular style of "multi position" links.

Hope this helps a bit more.
