1981 GS 550 L Project Bike

[Murphy67]

Hello All:

Very happy to find this forum. Just purchased a 1981 GS 550 L with my friend's son to get him some summer wheels. Its got some problems like usual, brakes and all the carbs and related hardware were off the bike in a tote. All carbs were off the mounting rails too. At least each carb was clean and assembled. If anyone has some clear photos of the attachments for the choke and throttle cable attachment would be extremely helpful. I suppose I should be asking these kinds of things in the General Forum section.

Ive been looking for the L model service manual and thus far I have not found one that talks about a quad carb setup on a 550. When did the transition to a twin carb setup?

Thanks in Advance.

Welcome.

You can find a service manual here : http://members.dslextreme.com/users/bikecliff/
Lots of great documentation there.

For the 1981 model you want "GS550 ('77-'82) Service Manual (72MB)"

Do you have a twin carb setup with the bike ?
Should be 4 carbs.

The 'two carb' set-up you are talking about came out in 1983 - it's actually two pairs of two carbs, each pair fitted closely together.

The choke attachment varies according to model year - does yours have the lever on the bars, below the left switch?

It does have 4 carb setup, but the manuals I found so far showed the twins. Thanks

Is it best to go out of this forum now and use the General questions forum?

Choke pull is mounted dead center on the steering below the switch.

It is customary to post questions to the specific subcategories.
That makes is easier for the next guy to find answers that have already been asked.
Also some questions turn a thread into a loooong conversation,
so it's best to post them seperately to avoid one single thread
with multiple conversations at the same time.
So yes, that would be the best thing but it's not mandatory.
