    I'm on the lookout for a right fork slider for a duel disk conversion on the '76 R90/6 with 40mm ATE calipers. They're somewhere between rocking horse poo and hens teeth.

    Can I use the fork slider from a R100RS? My reading on the Haynes suggests the stanchion diameters won't match. Is that correct, is there no other right-hand slider, other than a R90S right slider that will fit?

    Cheers.

    I have a set from a 1978 R100RS and one earlier one (not sure where it came from) do you know the part number you are looking for?

    Hi Bulldust,
    According to the MAX BMW Parts Fiche I'm looking for Part #31421233511 (RIGHT FORK SLIDER - 17MM)

    Edit: It looks like the 1978 R100RS sliders are a different part number, but R100/7 1976-1978 sliders are the same.

    Sorry just checked my 1978 RS ones have a larger axel, and my brand new NOS 1974 17MM fork leg is a left hand one 31421233151.

    Thanks Mate,

    I'll keep looking for a non R90S slider for the project.

    Cheers.

    Oh Bullbust, you ask too much. I've read about that sort of carry-on. I'm impressed by those who have the skills and not any sort of purist, but as far as this item goes, it's a matter of just tracking down the right part.

    Has anyone found a substitute to the BMW Rubber Boot used on the forks? My '91 GS uses the 15 rib boot. I'm starting to look at some of the local 4-wheel drive shops to see if they have any rubber boots they use on shocks that might be usable on the forks.

    Any help is appreciated and I'll report back on what I find.

    And I have the 11 Ribs......even more expensive than the 15s.:eek1:eek1:eek1

    I was looking a little while ago and found this, matches (or close) the fork/lowers for size. 30mmx60mm.
    They give the total lenght as 10.5", also a match.

    I put Rancho shock boots on. They look good and fit perfect on the top and bottom. They are not meant to be on a show bike. I repeat. I am not Perry B. I resurrect bikes, not restore them. They do the job and look good but the faithful ones go ape shit over not using original parts sometimes. I do use BMW clamps. More into function on a non-museum daily rider than some...

    Thanks...always tought those would fit from eyeballing too many lifted pick-up trucks up this way.:wink:

    Don't care much about faithfulness myself but have to stay very close to the stock look. Collector's plates= much cheaper insurance.:clap

    OK I'll get a set, if any issues,as in the insurance assessor counting ribs:evil, I'll just trade them with the OEMs I gave a friend 15+ years ago for his old Bonneville, that bike still hasn't moved.:D

    Found a pic....if anyone cares about counting ribs. :huh

    They fit at the top perfect. Have to drive the pin into the brace. At the bottom them have two “slits” on each side. I wrap the fork leg with a mess cloth that acts like a filter for dirt and than clamp. Seems to work good. Sure better than none at all.

    Terry, look for a PM from me soon about some speedo work. Thanks.

    Thanks for the tip on those fork gaitors! I've spent the rediculous sum of $70 for the correct gaitors and don't intend doing that ever again. Thanks for the 'heads up' - will watch for your PM.

    $70 for fork gaiters? That's nothing. I spent something like $76 for speedo and tach eyebrows. I was one week into quitting cigarettes tho and this was approximately how much money I spent every week on cigarettes. So I did it on poipose.

    Don't know if anyone is replacing theirs because they look all "saggy" or because of cracks.

    Mine were "saggy" they would touch the front of the fork tubes, do to time/gravity.

    I drilled a vent hole on the other side and turned them 180 deg. Now, no sag.

    Is that being too Anal?:ear

    Most the time I replace because they are not salvageable, even cracked ones that dont go all of the way through are replaced and 60% of the bikes I find dont have any. Good excuse to rebuild the forks and put new seals in anyway, most of the bikes I get have been sitting for some time...
