Carb Identification

Postby abatoire » Sun Oct 24, 2010 6:56 am


I just bougth a 1976 GL1000 in near mint condition, with only 9100km. It was a kind of "Barn Found".
As I started the restoration i have got trouble with the Carb: the number on the Carb does not match with any serial numbers listed in my Handbook for GL1000. (Altough the Frame, Engime and Rear Transmission numbers are matcing for the 1976 General Europian or German market.)

I suspect that the Carb was changed to one from GL1100.
Can anyone help meg to identifie my Carb?

The Number seem to be: 49A
Please see the attached picture!

Thanks for all the help!

Hi Abatoire, Just come across your post.
I'm pretty sure the number you seek is stamped on the top side of the carb body next to the slide body that bolts up against the plenham chamber.
It will be something like 755A.
If you want to confirm, Randakks have carb info in the Tech Tips section of the site.
Good luck

Pedro ;)

Looking at the photo they look like GL1100 carbs.

Yeah that`s the catch! There is no any number on the topside!
I have fund Randakks hompage with the instructions long ago, but still... this is the only number in can find it on the Carb.
These are Kei-Hin Carbs that`s for sure, but with a two digit serial.

Probably the prewious owner has chaged the factory Carbs to some other product from Kei-Hin, witch compatible with the engine but not listed in the Factory Charts.
OR the Slide Body is original and the Carb came from some later engine (GL1100/GJ1200).

Can't say what year but those are definitely 1100 carbs.

Correct, those are definitely 1100 carbs. 1000 carbs look quite different on top:

GL1000 Carburetors

Thanks for the Info!!!!
It looks like it is going to be a Carb from GL1100.
Can anyboy check this number (49A, see the picture) in GL1100 Handbook, by any chance?

Clean the top of the carb body, the flat part between the plenum and the carb intake. Never seen carbs that didn't have the model number stamped there. Definately,the carbs you have first came on the '80 GL1100s.
The 1100 carbs will work on the 1000, no problem. The correct carbs for a '76 are harder to come by(meaning expensive) as so few were made the first two years. The rebuild kits for the 1100s are much cheaper, too. Try'em!
