Hi everyone,
The following Ho To... is showing how to re-oil of the Rear Shock on a ST1300 as shown by PC (Thanks mate :-++).
To tell if this is something that you could benefit from follow these simple steps:
* Locate your pre-load adjuster (the big black knob located on the left side of the bike between the seat and the foot pegs :wink1)
Every time the knob is turned 180° there should be a click (there are a total of 35 clicks from LOW to HIGH).
* Turn it all the way left (counterclockwise)
* Slowly turn it right (clockwise).
Turn the knob (clockwise) until you feel pressure or resistance, if it takes more than 1 to 2 clicks that will indicate a loss of oil from reservoir.
If you have this occour this procedure will fix the issue :thumbsup
Okay lets get started :grin
ONE
* Remove the left side saddle bag
* Remove the seats
* Remove the plastic above the pre-load adjuster
* Turn the pre-load adjuster as low as possible (counterclockwise) to relieve pressure.

TWO
* Remove the screw holding the bar that the pre-load adjuster is mounted on where it connects to the frame.

THREE
* Make note of the hose location on the adjuster so it can be reinstalled at the same angle.
* Remove the hose from the end. (Make sure to keep the hose end up so the oil inside won't spill out and be careful not to loose the two copper washers on each side of the bolt.)

FOUR
Place the hose upright like in the picture below to stop any oil leaking out of the hose.

FIVE
* Tip out any remaining oil in the reservoir inside the pre-load adjuster and use a screwdriver to push the piston down inside the reservoir.

SIX
* Clean out the reservoir with a cleaning spray (PC uses "Break & Parts Cleaner" and "WD40")
* Screw the pre-load adjuster in and out to get the cleaner all the way through.

SEVEN
* Push the piston back down inside the reservoir.
* Using a syringe (No needle tip needed) fill the reservoir with fork oil

EIGHT
* Reattach the hose (make sure the hose returns to the same angle as before and the copper washers are on each side of the bolt)

NINE
* Screw the pre-load adjuster in and out to get the oil into system
* If it still takes a number of turns (clockwise) till you start to get a click follow the steps below. If it is working go to TEN.
*** Turn the pre-load adjuster as low as possible and remove the hose from the end.

*** Push the piston back down inside the reservoir and top up the reservoir with more oil then reattach the hose to the pre-load adjuster .

*** Screw the pre-load adjuster in and out to get the oil into system.
*** If it still takes a number of turns (clockwise) till you start to get a click repeat the three steps above.
TEN
* Once you are done adding the oil and have reattached the hose:
* Remount the bar that the pre-load adjuster is attached to.
* Replace the plastic above the pre-load adjuster
* Replace the seats
* Replace the left side saddle bag
Anyway that's it, now go for a ride and enjoy the comfort :runyay
Thanks to PC for all this info :-++ and I hope it is of some help to you all :thumbsup
Cheers

Must do mine one day... :think1

If the oil level is low it must have gone somewhere; just replacing the oil won't fix it.

Thanks all for this thread. After talking to PC at the Thursday RTE I confirmed that STrudel has exactly this issue, which explains why his dragging his belly more than at first.
Alan’s comment “it must have gone somewhere” is logical. Are there any common trouble spots that should be checked for leaks?
-
Strange coincidence! I'd noticed after our ride on the horrible undulating road last weekend that there was an odd "thump" in the rear in some situations. I then read up about the adjuster here and on the USA site and serviced mine yesterday. It took 45ml of fork oil. I haven't had a chance to test ride it (busy this morning, and it's raining steadily). There's no oil on the ground under the bike, but maybe it has to be exercised to leak. If there is a leak I presume the shock will have to be overhauled or replaced.

I don’t think you should have any concerns about the shock. My understanding of the preload adjuster is that it is basically a little hydraulic jack that compressors the spring To stiffen the rear suspension to accomodate for different weights and road condition Not a lot different from a car, the spring carrying the weight and the shock doing the dampening
-
Yep, that is exactly what it is, a hydraulic preload adjuster. Over the years a little bit of oil leaks past the seals and washers. Remember to replace the copper washers on the banjo bolt when you top up the oil + release the banjo bolt to remove the air trapped in the system after you top it up.
Did mine a few years ago, and is currently only 1 click off where it was after I did it. Before I topped it up it was 10+ clicks before there was any resistance.

Did mine yesterday morning. My preload was doing nothing for the first 20 clicks. It took about 10ml and it’s good as new. Went for a ride with my pillion yesterday and it handled the tight Mt glorious twisties an absolute treat. Plenty of boot scraping on my part but nothing metallic. Thanks again everyone, especially PC who was the first to bring it to my attention.

Here's yet another "how to". https://youtu.be/IgOWLfPiVQQ
As a bonus it also shows you how to adjust the rebound damping. :clap
Coming across this video a coupla weeks ago encouraged me to venture out to the garage to re-do mine... :thumbs
