I shouldn�t get too hung up on small differences in spring tension between the two valves Steve. You�ve got to remember that the two fork legs work together as one, a pair; the overall damping effect will always be an average of that set in each fork leg. Obviously a massive discrepancy will noticeably lessen or increase the damping effect, but you won�t get any �imbalance� as both legs are clamped tight to one wheel; the force only acts on one point. It�s not the same thing as fitting different rate dampers to each side of a car axle. You may remember in the past quite a few bikes had compression damping in one fork leg and rebound in the other. No harm in getting it right though. I got over-excited and just put mine in as they were and they achieved the desired effect.
Interesting about the nuts. I wonder how mine are doing? Haven�t noticed any change in damping though since I fitted them.
There are of course �Nyloc� and nylon locking nuts � they are not all equal. Nyloc (the brand) use nylon 6.6 polyamide inserts which are chemical resistant, but other brands do not and the insert will degrade over time when exposed to oil, fuel, UV and even moisture. I suspect the ones supplied might not by oil resistant which is possibly why they�ve loosened? I wonder what brand/spec of nut Teknik use?
I think, based on Seahorse�s experience, when I next strip my forks down I might just use full metal locking nuts such as those made by Aerotight.
