    Moto Bins no longer use the postal service - they use one of the air frieght crooks , so expext at least twice long for delivey and threeto four times the cost.

    I used to get things in 4/5 days to Oz around at $50/60- delivey - last time it was four weeks and $165- and that was for a exhaust Y piece weighing 3 lbs .

    AND THEY LEAVE IT AT THE NEAREST POST OFFICE ANYWAY- SOI HAVE TO PICK IT UP TOO.!

    I don't think anything but a BMW petcock will work. So rebuild yours for a few bucks or buy a used one and rebuild it. Airhead salvage, ebay, IBMWR would be a source for used. In the end you trade dollars for your time.

    I put a R80gs master cylinder on the bar of my 76 R90/6. Braided hose properly blead and adjusted ATE caliper. The GS cylinder is the same size as the under tank unit. Lever requires major effort to get decent brake action. I think I gave up some mechanical advantige provided by the leverd cable to M/C on the under tank unit.
    Do I need to push more or less flued volume to the caliper? Seems like sleeving down would work.
    Any thoughts? Helpfull ones preferd.

    You're correct, mhass. Sleeving the master cyl down to a smaller dia will increase the hydraulic pressure, and so, the "power" of your front brake.

    It'll also cause the lever to feel a little less "wooden". ie: there should be a slight increase in lever travel over the effective range of brake function.

    You could always spend several hours drilling the bolt heads and saftey wiring them! Or not.
    I've replaced exactly one oil pan gasket. I generally just grease them before assembly. I don't have any leaks, and the gasket parts gracefully if of some silly reason I need to drop the pan. The one I had to replace was glued to the pan by a DPO.

    Excellent string gentlemen....Some great information here.

    Since 1983 I have purchased parts for my vintage Brit bikes from Domiracer but they have added airhead to their inventory. I just purchased a "aftermarket" set of stock handlebars for my R90/6. Made in Taiwan but of excellent quality and a perfect fit...They have several other styles.

    For those who've got/get a fried sender I just discovered our local electronics parts store (Jaycar) has spitting-image replacements for $AU20!

    Sure beats paying through the nose at a dealer for a replacement unit... the best price i could find for a reco unit was $AU110.

    From what I can see the sender is the only thing that can fail...

    I'm still waiting to test mine: when i pulled it apart it looked like it'd been assembled in a sand storm! :huh

    Does anyone know if there is a non-OEM air filter out there that'll fit a /5? Has anyone been able to determine if any of the thousand or so filters available from Fram and the like are similar enough to the stocker to work?

    I'm looking for a replacement which I don't have to mail order or get from a BMW dealer, if that's possible.

    Here's where I sourced one when I needed a replacement. Around AU$20 indeed. http://content.honeywell.com/sensing/prodinfo/solidstate/catalog/c20050.pdf

    The starter relay on my r80g/s started not working... and the outer cover would come off when i pulled it from it's socket.
    Time for a new one, said i...
    Quick call to local BM shop $AU84! :eek1 What the... are those spades platinum! BM wreckers: $45 :eek1
    There's no way I'm gonna splash that sort of payola for a simple relay.
    Well, of course, it's not just a "simple" relay. Turns out that BMW wanted a diode in it so you had to get that specific ($BIG$) one. Bugger that!
    Why can;'t the diode be wired externally?
    Well, as it turns out, it can.
    I bought a basic Bosch four pin 30amp relay, a relay socket, a few spade connectors, and 12v5w diode. Wired 'em up - as per the diagram on the old relay - and Bob's yer uncle...
    All components from local electronics store (Jaycar).
    Cost: Relay $4.50, Socket $3.80, Diode $4.80 (had to buy 4), spade connectors $~1.20.
    Total: $14.30
    And if i ever need another relay i can get one at any car parts joint.
    Another small victory for the little guy. :D

    Motorworks sent me Goetze pistons rings, P/N 08-700900-00 for std bore '77 1000cc barrels (iron lined). Goetze is a trademark of Federal Mogul Corp. This complements Lornce's information on his Volkswagen cast rings, I believe.

    Just picked up my first BMW, a 91 R100 GS. I currently own a concours and a klr. For the concours i go to murph's and for the klr i go to happy trails for all of my goodies.

    My question is this... is there a go-to place for farkles for my bumblebee?

    What i am searching for is oil filters, blank keys, and the possibility of putting a givi box on my back.

    Where shall i search for the holy grail of GS Parts?:eek1

    EDIT: I HAVE A PROBLEM WITH THESE. STAND BY FOR FURTHER info.

    I screwed up an OD measurement, apparently. Its 20, not 21.

    Thanks for that. The first supplier I called wanted $22.65 for one or $16- each if I wanted eight. Special order , 3/4 weeks . Bummer.

    Second supplier , $A3.97 each, in stock. Yes!! I picked them up straight away , and got a neeedle roller small end for my B44 at the same time for $6.20 , against $36- for the bronze bush plus reaming, if I could find someone with a jig to do it insitu.

    Now I just got to find someone in Oz with a six piston caliper who wants less than $250.00 for it------
