Apologies if this has been posted elsewhere. I've had a look!
Thanks to all the excellent advice on here, I got hold of a 2012 XT660Z with 2468 miles for �4k. It hasn't been out in the rain! As part of the farkling for a long trip I've got Ohlins front springs. On dismantling the forks the oil in one leg was blue, and the other black (as in dirty), and the springs were different lengths (about 5mm). Rather than get hold of a Yamaha damper rod holder, I had a hunt on t'Interweb and found a damper rod holding tool for a GPZ900R here: http://www.gpzzone.co.uk/acatalog/Tools.html (scroll down) For the sake of a Tenner (�10.12!) I thought I'd have a try.
Happy to say it fitted perfectly, and you can see the indentations half way up the wedge where it was forced into the inner tube by me hitting the assembly bolt with an impact driver.
