R1100 O-ring for Air-bypass screw. Part number?

[Two wheels good]

Hi
I need new O-rings for the air-bypass screws on a 1996 R1100
Can anyone tell me the OEM part number - the main-dealer's parts fiche doesn't show an o-ring and they are unable to order it.

Otherwise I'll have to try my luck with a local motor factors.

Thanks
David
PS I have consulted the catalogues of the usual independent parts suppliers.

If you are talking about item 18 in this diagram...

....then there is no o-ring listed for it. Are you sure the o-rings are original and haven't been added by a previous owner?

Or maybe the o-ring is supplied with the screw itself? If that's the case you'd probably be better going to your local motor factor or buying a bag of assorted o-rings and finding one that matches.

Yep, that's the one - part no. 18. Good point - it may be included with the screw.

Part #18 has a part number of: 13541342074

Motorworks use the last 5 numbers of the BM part number and it shows:

Confused, I am

Thanks again

That's useful to know.

My local friendly motorcycle shop helped me out but I'll need to get the correct size o-rings soon.
