A good point from Mr G - all measurements should be taken to the flat part of the fork tops, not to the top of the adjusters.
Thanks for those, slob. I see the measurements are taken from the
bottom of the lower yoke, not the top, as I had thought. Confusingly,(for me anyway), the measurements for my Evo are taken from the
top of the lower yoke.
For what it's worth, here's a publicity shot of the 900 Sie showing the amount of fork above the yoke as a guide. (Of course, there's no guarantee that they were correctly set up for the photo!)
