Hey all, any assistance from Boxxer / suspension gurus would be much appreciated...
I've just given my forks (2006 Boxxer races) a service and I've run into a little problem with the rebound adjuster. The forks are assembled and they're working fine, the problem is that the rebound adjuster at the foot of the fork leg won't budge. Well, not without more force than I'm willing to apply (at least for the moment
). Prior to refilling the damper leg with oil, I fully opened the rebound, then even backed it closed a touch to make sure it wasn't jammed open. It didn't feel stiff or at all unusual.
When I've reinstalled the lower bolts, the bolt on the damper side will tighten, but not overtighten. It's tight, but at a point where it just spins rather than getting tighter. I assume this is the rod / rebound damper spinning in the fork legs. I can't remember if this was the case last time I serviced the forks. Is it possible that this has somehow resulted in the damper jamming open / closed?
But, going with the theory that the rebound has been jammed by trying to turn it too far in the one direction, I don't believe that the fork rebound is as overly fast or slow as I would expect it would be if the rebound damper had been jammed open / closed.
I'm going to strip the forks again to see if I can find the issue. If it comes down to it I'll try to apply force to get it to move, but only as a last resort, and would obviously want to make sure I was turning the adjuster the right way and not just jamming it further. Is there any way to tell if the rebound is open / closed just by looking at the damper?
Oh yeah, just in case it helps with the diagnosis, during the service, I didn't remove either of the shaft assemblies from the uppers. Also, prior to the service I've been having problems with the rebound speeding up during a day of runs. Not sure if the damper gradually adjusts itself open, or there's another issue at work.
Any ideas?
Cheers.
