Jes' wondering out loud. I have option of substituting SJ hoop style instead, but would rather not fool with it if the T'fix works ok. Looks tight so I'd be curious to hear from someone who might have a G/S with TKC's on and the same brace.

Here's where I just got my pair for $199.99 (**edit, they went up $10)

Do you still have the part numbers for the pair?
I'm looking at the same upgrade.

Did I get the right rack?


Just changed all the oils - the previous owner had a strong arm and the threads are just holding in there - I can see helicoils in my future

Any help or suggestions appreciated.

I would say they are for the back signal lights if you don't use the rear rack.

R100G/S - 2yrs and 3mos later

(GS downgrades or G/S upgrades, does it matter?)

It isn't completely finished yet, couple of things here and there, but this is what I have been working on for the last 2 years. It can be considered a heavily mod'ed G/S or a downgraded R100GS (which is what I had in mind):



(Click for higher resolution)





Featuring
  • 1990 BMW New Zealand R80GS Frame, legally registered in Ontario, Canada
  • 985cc rebuilt engine with '77 R100S pistons+barrels (A-bore), 1980 R100CS big valve dual-plugged heads, 1983 R80RT bottom end
  • Overhauled 40mm Bings, SLS system removed, jetted with160 main jets, 2.66 needle jets (new needles 3rd notch) and 45 idle (initial setting)
  • Low mileage stainless steel R100R exhaust system, de-"chromed" and weight relieved, seems to work very well with the rest of the engine
  • OMEGA Electronic Ignition with two dual tower Dynatek high-energy ignition coils (backup: points-in-beancan ignition with 2.8Ohm HD dual coils)
  • 450W voltage regulator/rectifier combo (backup: BMW stock components)
  • remanufactured 280W altermator stator and new rotor (Rick Jones) (backup: known good spares)
  • 1982 G/S gearbox, completely rebuilt and modified with a complete set of late design 17.5 Helical gears, mod'ed with a long 5th (HPN)
  • 1987 R80RT monolever 37/11 4-lug final drive
  • Monolever swingarm with 1 1/4 in extension
  • EXCEL tube-type rims 21x1.85 and 17x2.50 super-laced to refurished, low mileage 1993 GS front and rear hubs with extrastrong stainless steel spokes/nipples (Woody's Wheelworks)
  • Stock 1989 GS Marcocchi 40mm forks with RaceTech Gold Valve
  • CC Products fork brace from SJBMW
  • New Ohlins Rear Shock, setup for 220lbs and 1 1/4 in swingarm extension
  • Brake modification to a 4-piston Brembo caliper (1999 BMW K1200S) with 13mm m/c and Spiegler SS brakeline
  • Large single beam 9" Clearglas Chrome Headlight with Xenon HID conversion (triples light output)
  • Trailtech Vapor Motorcycle computer with digital voltmeter
  • BMW Speedster windscreen
  • Hyperlite Flashing Brake Light
  • original GS Krauser luggage racks for equal size bags
  • GS soloseat and rack (or Corbin Gunfighter alternatively)
Where is it going to go? This year it will be gravelracing (sorry: off-roading) in CO, NM, TX and OK and it will go to Alaska within the next 3-4 years.

PD Tank Rubbers

Been looking at all the usual online websites for rear L shaped tank rubbers for the PD tank on my 1984 R80G/S. Its where the tank rests on the top frame rail.

Any suggestions?

I just noticed your posting and lack of reply!

Amazingly, I've found that BMW still stocks a lot of OEM parts (avail through dealers - Bob's BMW is my personal favorite). A few parts are unobtanium and watching online auctions and bike website forums is worth it if you are in need of something. Unfortunately prices have skyrocketed and I've seen outrageous $ paid for G/S specific stuff.

I think you are looking at one resource website right here. Also check out: airheads.com
boxerworks.com
horizonsunlimited.com

micapeak.com for general info.

realoem.com has parts microfiches online which are essential.

Anton Largiader (Anton around here) has useful info on his website, and he works on beemers.

google searches are your friend.

A lot of stuff is common to other airheads (you prob know that already).

There's no G/S specific faq/website that I know of. I wish there was.

I just picked up an 86 too, so although I owned an airhead before, I'm in the same boat.

Sorry if I just repeated stuff you already know

Cheers!

There are a couple of angle brackets that mount to the frame, that you can then use thumb screws to solidly lock the two together. Be warned that those thumb screws can work their way loose and they're not cheap. After replacing a few, I drilled the ends for a hairpin clip and haven't lost one since.

As for the L shaped gas tank rubber, they are crazy expensive. I couldn't keep mine glued, they kept falling off. I found that the one for the 100GS will work, but needs to be thinner. I used the hand held grinder to remove some material and it works much better than the stock ones. And they're not anywhere near the cost.

Maybe I'm mis-using the term. I call anything so pricey and "exotic" that it's out of reach of mere mortals "unobtanium". 32L tank in primer for $1365, outrageous decals (foil sqares are currently arond $13-15 each, rainbow is almost $ 30 ea. not including text), etc. make it so they might as well be non-existent for me (and I think most people). USed parts come up fairly infrequently and when they do they are top-dollar (why else would a G/S sell for $5k when a very similar ST in sim shape might only command $2500?).

How'bout not unobtainable, just out of reach...?

Of course, I'm still diggin' the bike. One could argue that new bodywork for a sportbike is just as bad.

Now, back to worrying whether I've got a circlip or not

Gottcha, that makes sense...

Here's a note from snowbum... what year is your G/S?

http://www.cdegroot.com/cgi-bin/mirr...ansmission.htm

OVERVIEW of the circlip problem:From sometime towards the end of the 1984 production year, or beginning of the 1985 production year, BMW's transmission maker made a modification to the transmission. On the output shaft, they left out a snap ring (circlip) and the associated output shaft groove...located at the nose end. The part number for the shaft was not changed. That modification can and did give a lot of grief to owners. About a decade later the design reverted back to the original reliable version. A number of these 'circlipless' transmissions have failed, some have had catastrophic failures, ripping the transmission to pieces.
Here is a link to Anton's website, with
