One for the suspension gurus..
Have been fettling the 675 with a view to getting out on the first track day. Worked through a couple of the Dave Moss suspension tuning videos, and managed to get the sag set correctly - which made quite a difference to how the bike feels in corners, as it was set up far too stiffly for my weight. Flushed with this initial success, I felt emboldened enough to move on to tackle the compression and rebound damping.
I have run into what seems an anomaly with the rebound damping on the front forks. The recommended settings vary from 4-6 clicks out, depending on who you listen to, out of a maximum of 14(?) on the rebound adjuster screws. I set them at that and the forks seem appropriately damped (to my untrained eye).
In order to test the effects of altering the rebound damping, I wound the adjusters fully in and out to see what happened. Full in, the forks are clearly over damped, and rise very slowly after you compress them as you would expect. When I back off the damping all the way out and bounce the forks though, there is still seemingly a lot of residual damping. They never get to the point of being underdamped, and overshooting when you bounce them. Strikes me as a bit odd.
I was wondering whether that's normal with some fork designs, and to be expected, or do I really need to start thinking about checking the levels and viscosity of the oil in the forks ?
