I took my preloader of and followed the instruction to add some hyrdraulic jack oil to the preloader. Once I got it off there was no "plunger" there to depress to get the oil into the body of the preloader. I had read about caution being taken not to press it in with a sharp object but I didn't even notice one there! I added only a couple tablespoons to bring it to overflowing.
Am I missing something? My bikes and 04', should I look for a used preloader?
Any helps appreciated!!!

Keep em in the wind!
:bmw:

A couple questions. I read that you followed the instructions, but just to make sure, did you back the adjuster all the way out, counter-clockwise? After doing that, did you use a hex key inserted in the hole in the adjuster to push the plunger back? It takes a little effort to get it to move. Not "Arnold" kind of effort, but a firm push.

If you did those two things, that's all there is to do. I'm not sure how much oil the adjuster holds, but it's not much. I'm sure somebody here has measured the amount they put in. I haven't, prior to installing Ohlins. I opened the bottle of jack oil and dripped it in til full.

Thanks for the reply Lee... yeah I was sure to back the adjuster all the way out, when I was done it did some to help. I just didn't feel anything resembling a plunger when I pushed in with an allen wrench... no noticeable resistance, it just felt like it bottomed out, nothing was going to move.

The few times that I refilled the adjuster on the 2000 model, when I pushed the hex key into the hole, felt the plunger, and pushed, it moved back with a wooshing sort of sound. You may not have pushed hard enough on the plunger. It didn't move much, maybe 1/4 of an inch, but I definitely heard it and felt it. I assume if the adjuster was nearly bottomed out clockwise, then turned counter-clockwise fully, the plunger would have farther to move. I can't say this with certainty, but it would seem to make sense.

Could some tell me before I do it, how to fill the preloader? :confused: and whats needed.
My bike has the oem stock rear shock, with 54k miles on it and I ride 2 up 98% of the time. The kickstand or center stand hits the ground at times when Im in corners and speed bumps the guard smacks at low speed. :mad:

I would like to try to add more oil and see if that helps.. But If not who has a good heavy spring to replace it. :rolleyes:

Ty, but I was looking for some pics... I think I got it, but sometimes a few pics can tell a lot more about what your doing wrong..
:confused:

I have been looking for Video and pics for the k1200 but few are out there.
Look at this thread and see if it helps, go to post #16 by Warden Ross, and in post #26 Tony put together a nice PDF of the procedure. Getting ready to do this myself this evening.

Randy, did you have the bike up on the center stand when you backed off the pre-load cylinder? If you still had the weight of the bike on the rear tire when you backed off the pre-load, then it's entirely possible that the oil in the pre-load was pushing the plunger back for you. This situation would have made it very difficult to get the bike onto the center stand (unless it was one of the hydraulic ones).

Once I had the preloader off and I pushed the spring all the way down.. it made a click sound and I had to push firm to make it move. I used about 2 oz or so.. so it was very low. I loaded up the preloader and took it out and 100% better. It has a better ride and when Im dipping into a turn the stand isnt hitting the ground like it was... The other part is that I was told that the bike should hold 500 lbs. Now dose anyone know anything about the weight on the bike?
I also went to BMW asked about tires and was told that my rear tire at 976 lbs was good... I told them if the bike is 800 lbs and Im 400 lbs..(1200 lbs on a 976 lbs tire??) am I not over the max rating of that tire now? I was told it had good side walls... 020 tires are not sold for that bike anymore...
