Picked up my `new` 1100GS today from Suffolk. When mike was showing me round the bike he took the oil filler cap off and there were two rubber O rings instead of one. We kind of assumed the extra one must have been there for a reason but we could not get the cap back on with two rings so I set off with the one in and kept an eye on it. As soon as I opened up the bike as I left Fressingfield it started weeping! I stopped and had another go at fitting the extra O ring to no avail. I went about another 10 miles and it just got worse and my boot was covered in oil. I stopped again and tried to get that second ring in. I noticed that the plastic bit in the cylinder to which the cap located was not seated correctly and I used one of the tools to pop it out. I noticed it too had an O ring but this piece was a little distorted. I reckon the oil was actually seeping past the outside of this piece rather than the cap itself. I put it back in making sure the locating tab was in the correct position and got going again. It was still leaking, but nowhere near as much. Not the best intro into BMW ownership possibly. but everything else was good and contrary to what most say I took to the bike without any problems and I reckon it will prove perfect for me as I wanted the riding position of my XTZ660, but with more oomph.
I was hoping my first call to a BMW spares company would have taken a bit longer.
Is this a common problem?
 
Never heard of it before, common bit of bling is to replace the plastic with a metal alternative from Touratech / Wunderlich?

But if you do that you still retain the OE plastic socket in the rocker cover, so it wouldn't solve this particular leak. It's only about £6 for a new socket, new filler cap and both o-rings from a main dealer (assuming the 1100 items are the same as an 1150 - I replaced mine a few weeks ago) and they take less than a minute to fit. As first problems go it could have been worse!
 
I already ordered the bits from Moto Bins. I have ordered a cap, plastic ring bit that it locks into and an oil filter kit which says it comes with 2 filler O-rings. I assume these are the ones that I need for the cap and the plastic ring. If anyone knows otherwise let me know!
 
How easily did the oil filler insert come out of the cover? I am replacing my rocker covers soon and I will need to move this item and move it into the new covers.

Very easily - just lever it out with a large, flat-bladed screwdriver. Ideally you would replace the o-ring when you put it in the new cover.
 
I replaced the whole assembly but it would still leak around the outer ring......nothing some silicone wouldn't solve of course :comfort.
 
Bits arrived yesterday. Drifted it in with a large socket, took a minute. Dry on test ride to work this morning. All is well in the world :clap

If you’re replacing rocker covers I’d suggest getting a whole new filler cap and O ring assembly. Tried to be a cheap skate and didn’t replace the filler cap when I swapped my rocker covers just before a 2000 mile trip – ended up with an oily boot for a long way! YMMV.
