Rear damping adjuster stuck ...need help.

I haven't adjusted the rear damper dial for ages and when I tried it, it is stuck. Won't go towards S or H but does have a little play.

Sprayed it with WD40 a couple of times, no go. I also used a flat blade screwdriver to try to catch the dial jaggies but it won't budge.

Suggestions please? Thanks

Spray it again and let it penetrate for a while, then try working it loose gradually back and forth.

Thanks Invader. I sprayed a few more times n it was able to move towards SOFT. I then realized that I had max out on HARD. I adjusted d preload 1 notch to 6 n reduce damping by 7 clicks. Will give a try tomorrow.

Surprisingly, setting a stiffer pre-load (#2 from stiffest setting) does not cause a jerky/bumpy ride. My weight is around 68kg which should be 3rd notch away from the stiffest setting.

The tranny shifts smoother now (my chain has sufficient slack), and the seat height is a tad taller. The bike leans more when it is on its side stand.

Now, let's see if Preload at #2, rebound at 7 clicks (from H) cures the cuffing at the rear tires.

It'll still cuff. Rear spring rate is too high, especially for your weight. Now your setting is still stiff, but with a higher ride height. How about at #4 from highest preload, with rebound damping at 5 clicks from H, for now?

What you really need is a softer spring of about 750 lbs/in instead of stock 940 lbs/in... At 210 lbs (95 kg), my 800 lbs/in spring is perfect. It's much more compliant, and I get to use all of the suspension's lateral travel with proper sag setting.

I have been thinking about spring replacement as a cure for the overly stiff rear suspension. I have set sag and damping as per recommendations but still no joy. I weigh about 180, so maybe 200 lb. with all gear (in cold weather). Where can I get a spring of the correct length to fit stock shock?

Stock Shock Spring Rate: 16.7 kg/mm (933 lb/in)

kg/mm / 0.0179 = lb/in
lb/in X 0.0179 = Kg/mm

800 lb/in X 0.0179 = 14.32 kg/mm


15.2 kg/mm / 0.0179 = 849 lb/in

14.3 kg/mm / 0.0179 = 799 lb/in

13.8 kg/mm / 0.0179 = 771 lb/in

13.4 kg/mm / 0.0179 = 748 lb/in


For your weight Smiley, I'd go with a 13.8 kg/mm spring.

13.4 kg/mm for 150 lbs 2daMax.

I weigh about 169 ((77 kg) and I have my preload on softes setting to get about 1.9" of sag. Remember that you are adusting rebound damping and that has little/no affect on ride stiffness.

Have you checked your "sag"...?

Thanks for the spring info, Invader. I'm definitely going the spring exchange route rather than complete shock change.

After more feedback research from that thread, I'd recommend a 13.8 kg/mm spring for you.

I sort of wondered how RT came up with a rate of 17.5 kg/mm when I entered my weight, when their stock V spring rate is listed as 16.7 kg/mm? That would be a bit of a disaster if a guy were to buy an even stiffer spring than the already too stiff stocker. By the way mine's an '07, although I don't think there is a difference from the Mk2??

Spring rate requirement certainly is the same for all model years... I also have a rare 2007, made in Japan.

Their recommendation sure is too high, but it's how you access available springs to place an order. Make sure they don't ship via UPS.

I'll ride it for a while and check if it will cuff. I was on the factory setting when I realized that it was cuffing, and raised the rebound to more H. It worked for a long while but now I am seeing it again.

Will try out your recommendation if I see Mr. Cuff. Thanks for the advices.

If "Mr. Cuff" refers to the shock impacting the plastic side thingee - do the cut-back BEFORE you break the thingee.
