I've ordered new rubber connectors to fit the throttle bodies to the head.  Should the connectors be fitted dry or with a sealer?  If with a sealer, which should I use?  I'd used Dirko in the past on the old rubber connectors, but they began to leak within a few months. Crying or Very sad
Man, I hate the thought of working on those things again.  Space is so tight there....  Rolling Eyes

I'll be interested in the replies for this as I have to do this when I return from my trip. I would think no sealant but maybe a lite coat of wd-40 won't

 harm the rubbers. Just my two cents. Where did you get yours from and what was the cost?

Those rubber bits are depressingly expensive at the local BMW dealer, so I ordered them from Motobins.  I figure I saved around $50 US in so doing. I just hope they are promptly shipped, as I plan to ride to Yellowstone in early August.  Surprised-o: 
Fingers crossed....  Fitting intake rubbers 652573

woah there! stay away from rubber bits with any kind of oil based lubricants. there's a good chance they'll shorten the life of it. assemble with silicone grease if you need something to help them slip on or something like hylomar blue if you need something to help seal.

WD40 is for displacing water.

Hylomar Blue or Permatex Blue will do the job.

Catepillar rubber resists anything...but there is a problem..the top of the carburetor is 40mm and the bottom of the plastic plenum chamber is 43mm...the original BMW part may be the only answer. I will try the cat hose first

Best regards from CAT Dealer in Ger.
why do we sell rubber parts for CAT all the time

btw.
the lower side of the new intake rubbers has a little sealinglip .This is supposed to do its job.

if the Rubbers are ok:
you can mount them with 3-bond from BMW (usefull stuff anyway)
