How tough is it to turn the rear shock preload knob?

Post by pepsi »

how much resistance is there turning the rear shock preload knob? Does it move the shock at all? Raise the bike up or down? :-k Is the shock and/or adjuster repairable /serviceable ? Mine turns without much effort and the numbers in the little window revolve but it does not seem to do anything. I feel no detents either.

Hi, Unfortunately the manual doesn't explain the workings of the rear shock.

Its my guess that there's a hydraulic piston that acts against the spring to compress it ,turning the knob pumps up the oil or releases it,and all of our shocks that have no resistance felt in the preload adjuster have leaked the adjuster oil out and introduced air into the system rendering it ineffective.

It seems that a pressurized shock is a shipping taboo by air or land/sea :roll:

more to come

My knob works fine, thanks for asking. :mrgreen:

Easy to turn the adjuster wheel, you can feel clicks and see the numbers change slowly but it doesn't seem to have any noticeable effect. Just like the anti-dive units.

Much harder to turn the damping knob in the bellypan, it had snapped off my original shock. But again, at my level of riding ability, I can't tell any difference.

I had a GSX-R1100 with over 8M permutations of suspension adjustment but not one of 'em was any good... :lol:
