Fork seal replacement

Apologies for dragging this up 5 years late...

But the forks on an 11S are nothing like those on the GS.

I've taken the top cap off at the yoke and just got a bleed bolt.

Looks like you need to undo the clamps on the yoke on an 11S.

Very often when a leg starts leaking it will be caused by a piece if crud getting caught between the seal and the leg, this can often be fixed by running the thinest feeler gauge you can find round the inside of the seal no dismantling will need to be done, try this first before laying out any cash on parts

I have the parts to do the job, but having had a look, I reckon my MOT man was a bit OTT last year. So I'm not doing them yet.

I also smacked my finger with a hammer, then got oil all over my drive, as the drain can couldn't swallow it as quickly as the 11S ejected it...

So I've put everything away for the day.

My right hand leg leaks a touch after being stood up then stops again shortly afterwards. My MOT man last year didn't have a clue as to what he was looking at, he told me the forks didn't work and it was siezed solid at the front when i told him it was nothing like a normal pair of forks and showed him the front shoc he told me that "thats for the rear suspension" he got realy confused when i lifted the cover for the rear shoc and showed him that he then said " i will pass it this time but get it sorted before you bring it back"

Have a look for a thread on this forum from 2010 titled 'front forks r1100s' the author is some knob called r550s - the thread includes a link to some more information

Interesting.

Not sure how to pull the fork seals out without removing that tube - and I don't want to go to all the hassle of removing it!

You can get seals out by carefully drilling a small hole half way through the seal then screw a small self tapper into the hole pull out with plyers or use a small seal remover

Not that i've ever had to replace the seals or completely remove the stanchion , I have however dropped the stanchion out of the top yoke ( loosen one bolt)while moving bars between under /over the top yoke.
Did you get this far ? if so then the stanchion just pulls out and as per R550s link
This is in the photo at the start of this thread

The top end cap is blind (and can actually be levered out in-situ if you're so inclined) whereas the bottm end cap has a M8 threaded hole in the centre, into which the 'Drain Bolt' screws to hold the whole thing in place
