Just received an email response from the Kansas-based Bing Agency Internat'l requesting prices on some service bits. Jumping Jesus!
http://www.bingcarburetor.com/bmw/bmwcvkits.html
The following are for 32mm Cv carbs as on most of the R65:
Kit#2 $78.19
Kit#4 $129.72 for carbs 64/32/201 and up
Kit#6 $176.90 ditto above
Add alky resistant float and bowl kit to #6 for $122.79
Float and bowl kit alone $186.59
No prices provided for individual jets.
QUESTION? Any other sources out there for Bing bits at "real world" prices? Motobins?
I have rebuild kits for the carbs with new diaphragms and gaskets. $25.00 fixes two carbs. I am shocked, Shocked, I say, with a capital F. [smiley=furious3.gif]

Motobins might well be your next port of call.
I cannot remember my rebuild kits being anything like as expensive.
And you can get jets on thier own...ifI recall
-
I just priced the parts that I got from Bing about 2 years ago, that includes kit #6, plus all of the jets, atomizers, etc.
Came up with a 'list' price at Chicago BMW of $203.3, factor in their usual 20% discount and it comes out to about $163, plus shipping and handling.
So maybe ordering it 'piecemeal' may be a better value, as long as you can get all of the parts in a reasonable time-frame.
I was just looking at the manual I received from Bing, and on the front, it states : Sole Agent For: United States Canada South America Australia .
Guess they have a strangle hold on the market.
The parts that I ordered about 2 years ago, was only $125US, so their prices have indeed gone up !!!
I installed the alcohol resistant float kit , back in 1997, I think I paid $65US for it at the time, and I didn't think I got my moneys worth at that price.
Right now the floats are a little under $16US each, I think I would replace the stock foam floats every 5-6 years, instead of purchasing the alcohol resistant kit for the price they want for it.

Now that the £ is not worth as much, you might find Motobins prices more reasonable:

flugelnus.com has your basic "gasket and o-ring assortment" kit for $12.50. I believe they took over Eurotech's Airhead business and I used to buy the full kits (with diaphragms) from them for under $40. Maybe an e-mail to flugelnus might reveal they still carry the kits.

Flugelnus was my provider for the gasket/diaphragm kits. Nice folks.
Motobins will be my next stop.
Thanks, all. Will let you know what transpires across the pond.

I always wondered why Bing didn't note any prices on the website. Now I know. Wow! :o
-
YEA! [smiley=clap.gif] Motobins to the rescue. You can pretty much build up your carbs one piece at a time, if you wish, from these folks.

Time to start a list.

Does anybody have any experience with the "Stromberg" diaphragms? I seem to recall some discussion on boxerworks (years ago) with some claims that the Stromberg parts had stiffer rubber...

Ive just rebuilt both carbs with parts from motorworks the diaphragms were twice as thick as the ones that came out im sure they are stromberg (My brother rebuilt his as well. Mine is an 80 flat top bing his is a stromberg top with the return spring 81) but they both work ok all the jets are availiable individualy just give them the frame number and they will ensure they are right for that bike they ship to the USA and mighnt be worth a punt with the $ so strong

I live near by so i usualy ring and collect they seem to have good stock levels but marginaly higher prices than motobins that said everything is pukka

I noticed on the Motobins site, that they have OEM Bing diaphrams, and then another non-OEM diaphrams.
Non-OEM are less costly, anyone know the difference between the two ?
-
What I recall hearing about the stromberg parts is that the hard plastic disk on the top needs to be boiled in water to 'soften' it so that it will slide down over the top of the needle jet area, I think... and apparently the rubber is supposed to be thicker. I have no first hand experience with which to ascertain the veracity of these statements.

pre 81 there retained by a plastic ring which is best refitted warm 81 on there retained by 4 screws and a plate both are easy to strip and rebuild

It's Saturday and I just now hit Submit Order for my Bing 32mm R65 carb parts from Motobins.
I also noticed the lower prices for the "HYDRIN" diaphragms but there was no other info, re: Stromberg or else, about them. No matter, as I already have the diaphragms, gaskets and o-rings from Flugelnus
At current exchange rates, my parts (24 items) came to $117.00US plus whatever shipping costs turn up. Far lower than having to buy the outrageous "kits" offered out of Bingville, Kansas.
No, Toto, we ain't buying in Kansas anymore! [smiley=furious3.gif] No one gets in to see the BingWizard. Not no one.

MotoBins delivers my 32mm Bing bits! [smiley=thumbsup.gif]
Posted to carriage via Royal Air Mail -I love this- from Motobins on 01 April 2009. At my door 09 April 2009. Order 100% complete and at the website catalog prices, no surprise up-charges or increases.
I had almost placed an order for my 81's timing chain and related parts but skipped over to the 'Bins site just to check prices. Glad I did.
MotoBins offers a complete timing chain replacement kit for the R65 priced at $43.95US which includes the oil seal, gaskets needed (3) and all the hard parts. Kit even has a fresh O-ring for the bean can. Factoring in the 20% ChiBMW discount, I'm still looking at $53.00+. Royal Air vs Chicago shipping is a wee bit higher but it's still pretty much a wash.
What sent me back to England was MotoBins stated "95% delivery from stock". The odd Bing order convinced me these folks offer serious parts support for the vintage Airheads.
Right now, the USD is strong against the British Pound.
Look through the MotoBins site. Almost every part has a photograph rather than the sometimes odd artwork in the fiche pages. An educational tour.

So Monte, what all did you end up ordering from Motobins for your carb overhaul?
John M

John and others...
I had on hand the new diaphragms and a kit of the needed O-rings, enrichment valve gasket and the float bowl gasket. Earlier, I mentioned these came from Flugelnus http://www.flugelnus.com/ but I was in error. My records show they were outta Chi-Town BMW. Better prices.
MotoBins supplied the following bits... Some may be unnecessary but the carbs are as yet unopened so better safe than stopped:
Carb Top Screw (4)
Carb Mixture Tube, 32mm threaded (2)
Carb Main Jet Washer (2)
Carb Vacuum Take-Off screws (2)
Idle Mixture Screw 1970> (2)
Float Assembly 1970> (2)
Float Retaining Pin (2)
Float Needle (2)
Slide Needle 32mm 70-84 (2)
Idle Jet #40 (2)
Needle Jet # 2.66 (2)
Parts = 81.50 British Pounds - $117.00USD (about half what Bing NA wanted for their kits)
Air Carriage = 7.50 British Pounds - $10.98USD
1 British Pound = 1.46492 US Dollar as of 11 April 2009
Bob's BMW also has individual Bing parts but not anywhere close to the vast parts listing at M-Bins.

Monte,
A little late now, but you can use stainless countersunk AN, or NAS, 10-32 screws for the carb top, use the ones without any unthreaded shank.
They are a perfect fit !

Never too late, Bob Robert, and thanks for the tip. I have a tub full of 'em in a variety of lengths. I like the cad finish so will save the others. MotoBins sells 'em cheap so it's all good.[smiley=thumbsup.gif]

10x32 is a perfect fit? I coulda swore that screw was an M5x.8...

I had no problem installing them.
I don't remember the diameter and thread pitch, but when I had my carbs apart about 12 years ago, the OEM steel screws were in bad shape, and they looked like they were close to a 10-32 screw, tried them and they worked.
I did some calculating, and when I got all the dimensions, there was only a few thousandths of an inch difference in diameter, and thread pitch.

Some you'z guys may have these helpful Bing carb overhaul sites bookmarked, but for dems dat don't:

Quoting myself here. Of the four cross-point screws holding the carb tops onto the body -two screws per carb- one was totally cammed out by a PO and rusted up tight as a tick.
This morning, it was pretty simple to center up a bit and drill out the head using progressively larger bits. A small, tapered stone on the Dremel finished up the screw head removal without boogering up the carb top, as in mucho $$$.
Will remove the remaining threaded portion of the screw when the cables are removed along with the tops. So now I'm really motivated to overhaul the Bings as I can't ride without the screw! Plus, the '83 is apart for paint.
My day job is getting in the way of my fun jobs.
Happy Easter from a wet, chilly and almost burned up North Texas. Couple days of grass wildfires burned off 140,000+ acres plus and 100+ buildings/homes in the county just N'West of us. Luckily, all we got was smoke irritated eyes.

Mentioning buggering up the threaded hole on the carb body side, I've seen the hole drilled out , and a screw and self locking nut used instead.

That thought crossed my mind, Bob, just as the bit tried to "grab". :D

I have always used a hand impact for getting these screws out and it's never let me down. I always replace them with stainless steel allen head screws...

That's what I did, and I used anti-seize as well.

Bob, .8mm thread pitch works out to 31.75 TPI and I guess the nominal OD of a #10 screw must be around 5 mm. Learn something new every day...

The 5mm screw has a diameter of .197 inches, #10 screw has a diameter of .188, if you tried to put the 5mm screw in a #10 hole, it might be a tight fit.
