Try Motobins - they have a new listing for aftermarket 1000cc squish band pistons and would have OEM or secondhand too.

Got a link to that page? I looked but couldn't find them on Motobins. Thank you.

Um, the squish band pistons i was thinking of are the Omega forged race pistons on page 2 of the 2V pistons listing, probably not quite what you are after.

Well, not the price you are after.

The Wossner pistons sold by Moteren Israel are a nice bit of kit but dont have a squish band like the Omega.

Went to AutoZone today and theirs for a VW is $30. Is there a chance that there are two different ones?

I've said this before and I'll reiterate it now.
The voltage regulator from alot of European cars from the late 60s through early 80s in some cases are interchangeable.
Prices for these are all over the place due to different manufacturers, price gouging, discounting etc.
Before starting an actual career with BMW in 1995, I was a German car technician for the previous 18 years.
I had occasion to spend alot of time substituting parts from cars to bikes and vice versa.
The same regulator that was used on my 1969 SAAB 96 v4, (sold last year)
is used on my 1974 VW Bus. Also used on beetles that ran the Alternator.
The list is as long as your arm.

Prices vary. Attitudes are adjustable. Just walk in to a parts store and ask for a voltage regulator for a 1977 VW bus.
OR a 74 Porsche 914, the list and I could go on and on, but I'll spare everyone.
SURE you can get a Taiwanese voltage regulator for $16.95 if you spend enough time looking, but do you want the cheapest part possible on your bike? One that may leave you stranded somewhere on the side of the road?

ALSO as a proffesional parts guy, let me spell out a scenario for this situation, it goes like this:
You go into your local cheap-ass parts house you buy the cheap-ass regulator for the 77 VW bus. A month later it goes south in Bumfuck Maine or whatever, you take it back to the store for a warranty replacement and they find out it's not on the vehicle listed in their application chart....
Sorry bro no warranty. Part was not being used as intended.
It happens.

I don't buy voltage regulators any more. 2 reasons:
I have a box of good used ones AND they don't fail that often.
They get replaced alot because some folks throw parts at their bikes rather than diagnosing them first \\
Don't get me wrong, they fail, but not that often.

Bap-geon noted a change in parts numbers to:
- internal part #: 30051
- bosch part #: 0192062007

$40.86 before tax (and it was in stock, too)

any tip on a G/S headlight equivalent?

Hi I am trying to see if the Bosch S4 headlight on the R80G/S comes from the car industry. It looks so. There are S4 lights for sale online and in shops, but the one I want to replace has a thick side wall as opposed to being a dome glued to the reflector.
I think they look like old Porsche lights.
These are the numbers I fished from the wreckage of mine:
On thelens Bosch S4 SAE M80 DOT and on the inside there is a sticker that says Bosch Sweden 1305601137. BMW part number 63121244211, costs $!50+ Ouch.
I am looking for the exact replacement to keep the bike original.
Any leads greatly appreciated.
Thanks!

Are you looking to replace the headlight lense? The parts fiche shows that as being the $150+ part, but the bulb shows as a standard looking H4 bulb for $16+, which means the H4 bulb should be available through car parts stores.

The lense and reflector part, though, may be G/S specific. Hopefully someone will come up with a substitute if that's the part you need.

Possbily installed wrong-side up? Swapped rings from one side to the other? Even if all were perfectly re-installed, there would be some re-break-in time I should think....

BMW OIL PReSSURE SWITCHES

Same bar. rating (0.2-0.5) for the 1100 oilheads and the AIRHEADS. and they also share the same thread pitch and sealing crush-ring.
I had the one on my R1100RT-P fail today and stole the oilhead one out of my airhead to put back into an oilhead.

I'm interested in getting the Omega electric ignition for my R75/6 but it seems that the guy that was procuring these stateside has gone out of the business. See here: http://www.stephenbottcher.net/omega//index3.htm

Are there any other options out there? I like how the Omega is installed overtop the original points & advance for the ultimate redundancy.
