G'day All,

I sought out the rubber bellows that are fitted on the underside of the upper K100RS fairing and over the fork leg. 2 of them per bike.  The parts manual calls them gaskets, part # 46 63 1 45 0620, and they're now NLA.  Has anyone managed to source them elsewhere?  Any help greatly appreciated:-)

Cheers, Alan
'88 K100RS SE

That part was replaced by air inlets to help increase airflow inside the fairing to reduce engine heat on the rider. 

Get the air inlets and a pair of Rancho 1952 fork boots and you'll have the classic BMW look.  You will also be protecting your fork seals from damage.  I've done that to all my bricks, and so far have yet to need a fork seal replacement.

Thanks for the advice about the rubber boot replacement.  I think I prefer the chrome look forks and will stay with them, and replace seals as necessary:-)  However, the air scoops sound interesting.  I assume from what you've said that they're genuine parts and should be easily identified as superceding the old "boots".  I tried to order from a local dealer and they didn't come up as superceded, just NLA.  I'll try elsewhere and see what I can find.  Don't suppose you have a part # for the scoops?

BTW love your SE:-)

Cheers, Alan

Hi Alan,

       Here are the parts as per Bobs BMW. On the first link scroll across to RADIATOR TRIM PANEL CENTER and click on it to get the expanded parts list.

I believe the fork gaiters/bellows are really designed for cooler weather to block airflow. As such, to get them off/on requires that they be cut through to the center hole to get them around the stanchion. I have the air scoops on my 1985 K100RS and at speed I can feel the air being redirected if I put my hand just ahead and to the left or right of the gas tank.

MotorWorks has new/used gaiters and may have used scoops as well. See the last 2 links for those items.

I've replaced my fork seals once when I first got my Brick  20+ years ago. When I replaced them I packed thick silicone grease between the seal and the dust cover. I replace the grease every couple of years more often in dusty conditions. The grease traps any dust/crap that gets past the dust seal and lubes the fork seals.
Regards Martin.

Many thanks Martin & Tom,

All questions answered, and I didn't even break into a sweat:P lol  I've checked the links and have decided to go "standard" with boots, but no "overshoes".  To divert from standard is to risk fate, and perhaps start on the slippery slope towards Cafe Racerism:P

The advice about greasing the fork dust seals is a good one and it should go in all the manuals:-)

Cheers, and thanks again, Alan

Packing the front master cylinder entry and rear master cylinder boot with silicone grease will extend their lives it stops crap/water getting in. I'm currently running a Chinese $15.00 rear and my perfect OEM one went to a mate after his stuffed up. I do not have shares in the silicone grease industry.
Regards Martin.
