Never heard of that issue. It does take a lot of bag to turn the preload adjustment. Have your friend or father lift the back of the bike by the subframe to relieve the tension on the shock. No need to lift the bike off the ground but just enough to take most of the pressure off the shock. You need to turn like hell so poop before you try it!

My used 05RR was a total knuckle buster even with the bike suspended and both wheels free. I have a motion pro collar spanner and could not get a workable puchase on the preload cam with it.

A search turned up someones suggestion of using the new channel lock pliers on the collar. I was able to get one click using that method. I wanted three-ish to get my sag.

I installed an Ohlins with a hydraulic pre load knob out of frustration.

I also got rid of the progressive fork springs (and installed Ohlins Straight rates) because of their inability to properly set sag.

What a difference! My legs used to ache after a couple of hours assault on the twisties. I never knew I was fighting the bike that hard. Since getting the set up dialed in, I can ride all day without feeling like I've done a thousand squats.

Possibly the best thousand dollars I have spent on any bike.

If you have never adjusted it for a while it will be a real bitch to move. Might take alot to move it. Just be careful that you dont spin the spring and strip the mount. If you look at it you can see what i mean.

My bike has 6,000 miles on it and I can't get the damn thing to move. I've put it on jack stands, by the pegs so the wheel is hanging free. The bike moves and acts like it wants to jump off the jack stands. I would think with suck low miles, the shock would adjust easily. I guess I had better lose 50lbs or save up $1,000 for an ohlins rear shock.....BLEH!

Try spraying some penetrating oil (WD-40 or similar) in the gap area between the adjusting collar and the shock body. I would do it maybe twice a day for two or three days then give it a try again. I ended up taking the shock off of the bike and getting it out in the open where I could work on it more easily, and be able to put it in a vise. Just keep spraying it and sooner or later it will breal loose and you'll be able to adjust it.

I too bought an Ohlins (TTX36) for my 07 600RR trackbike. Having the hyd. preload adjuster on it is a breeze.

You've used the WD-40 before with no problem? I've read not to use it on our chains because the O-rings could possibly deteriorate.

There is a thread in the Maintainence Section where a member did a test on O-rings using all types of chemicals, one of which being WD-40.

Check and make sure that it isn't already at max or min. It isn't reccomended to go from say setting 0 to 7 or visa versa. My bike has over 30k on it and min adjusts with minimal effort. Penetrating oil can't hurt also, clean it off and see what setting the shock is currently at.

Know what's funny, the hydraulic preload on my Ohlins sticks past a couple turns in Like the 20 other people here a stuck stock shock collar is part of the reason I bought it. I just can't win. Luckily 0 preload is the setting for me, so I'd rather not ask questions and leave it alone if it leaves me alone...
