I wanted to run a couple ideas past any suspension-savy members out there:
I have an ES model Super Ten. I have put on a slightly heavier rear spring (476 LB/in). The rear rebound could use a boost (although its not terrible as-is). I run my suspension damping setting on Hard +2 to get more rebound damping, but I have a stiffer front end than I would like for general commuting.
I am wanting to attempt a simple fix without re-valving the rear shock. Here is my thingking...
- Idea 1: At some point, the Rear Rebound Damping stepper motor must be coupled to the rebound valve adjuster. I am wondering if it is possible to remove the motor from the shock without disassembling the entire shock. Then you may be able to adjust the coupling on the motor shaft (offset by some degree), then re-assemble. The rebound damping will now be in a new position although the stepper motor position hasn't changed. For example, if you have your suspension set to Standard, the rear damping will be somewhere in the Hard range.
- Idea 2: I need to verify with my O-scope, but I am betting the coupler on the rear shock is sending a stepper motor driver signal (pulse-count method). It may be possible to adjust the suspension to Standard, then unplug the rear shock. If the controller doesn't fault out right away, then you can switch the suspension to Soft. Then plug the rear shock back in, and adjust the suspension back to Standard. The Rear Rebound Damping stepper motor will be driven to the Hard range while the fork is only in the Standard range.
One catch may be the stepper motor controller feedback. I know the motorcycle is supposed to throw a fault if the suspension adjustment doesn't reach its set position, but I don't know if that relates to all stepper motors (preload and damping), or only the preload motor. If the feedback error is related to the damping motors also, then there are two possibilities...the feedback is driven from the stepper motor itself, or the feedback is driven from the damping adjustment itself (load-driven feedback). If it is motor-driven feedback, then removing the motor and adjusting the coupling position would be my only option. If it id load-driven feedback, then neither idea would work.
I'm probably going to try Idea 2 first because nothing needs dis-assembled, and I'll find out immediately if there is any feedback-related faults with the stepper motor control. I just figured I would check here to see if anyone has played around in this area before. If I don't hear back from anyone, I'll just dive in and experiment.
