Dual Weber Accelerator link

[WhoIsSea10]

I'm currently in the process of installing dual Webers on my 2002. I need help understanding how to link the throttle bar (mounted on top of the intake/carbs) to the actual accelerator linkage. Is there a specific mount that bolts to the firewall to aid in this? Or is it typically done by wire?

Post a picture of the parts you have there are several/many ways to do this with cable or rod or a combo of both.

First image was the connecting rod that was bolted to the firewall and swiveled.  It connected to a vertical rod leading down to the pedal box. Now I’m thinking to remove that rod and replace with a wire. (1st image was with the my previous 32/36 weber downdraft.)

So, if you use the over- bar style like that, just get another carburettor bar, like what you already have,

and enlarge the hole at the end, as orange, below.  Insert peg into it, per arrow, and put a small 

hairpin clip into it, and you're on your way.

 

On your way to synching the carbs.  a lot.

 

I found, in your situmification, with that abominimilization of a linkage, that it didn't

like to stay synchronised.  Or rather, one carb didn't like to stay synchronised with the other.

 

So I took off the arm at the back, and bought a little gizzer that fit between the carbs

(don't remember where- one of the name- brand Weber places)

stuck it in where I've made that green whatsey- hoosit in between, and life got 

a WHOLE lot easier.

 

just' sayin'.

 

Search 'DCOE linkage'  for more discussingtons.  www.google.com/ site:bmw2002faq.com "DCOE linkage"

or something equally codish- looking.

yeah, that green bit is the "Inter Connecting Linkage". I know it's supposed to be easier but there's no denying the rod style linkage looks so much nicer. I've heard of people tack welding their rod linkage to prevent any movement. So the kit I got has that "orange" arm (not installed yet) but I don't think it has the reach to connect to the accelerator rod. If i even tried, the rod would rub against the transmission. I think a simple wire might be the best solution.

I gots yer pixy right har, Toby... that DCOE throttle linky-gizzer that stays synched. ;-)

 

It's similar what I run too (I have an old Lotus short lever version). And you can pull it (cable/bar)or push it (bar).  With the over head style DCOE linkage Sea showed, you'd only use one carb arm then...

The old swivel arm that I had was too long and had to be removed to fit the dual dcoe. This is why i removed it and have been trying to figure out what to do. So far it seems like a drive-by-wire setup it the move

[Stevenc22]

Cable linkage from pedal up the firewall where it pulls on the rod linkage.

 

I also changed the turnbuckle connections out for 8mm ball connections which work so much smoother!

[WhoIsSea10]

This is exactly what i need

Or you might just use something that won't require trying to synch the carbs with the intermediate linkage parts.  About half of our sales are to folks replacing the generic over-bar or cable linkage kits.  And our system comes with everything you need from the pedla lever to the throttle shafts.

This ^
 

I’ve used the similar Ti linkage setup for many years with great results. Set it and practically forget it. Sync-ing is a very simple affair with this linkage.

This is really tempting even though the price is a little steep. I will email you soon about it, Hal

It might seem that way until you install it.  Independent BMW shops really like the system because it takes less than half the time to install, it includes everything needed, it doesn't require any adjustment or maintenance after installation, it looks fantastic, and they get no customer call backs.  If time is money, then this is actually the less expensive solution.

Looking forward to your email.

I put Hals linkage on about 6 months ago and haven't touched carbs since, It's the best out there, And believe me I tried a few before buying his

[WhoIsSea10]

Yeah, I made the purchase today. Can't wait to get it and finally get the carbs tuned.
