    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

I'm stupid, and need help recovering from a mistake...

I have a '79 GS550L. It would not run well, bad acceleration past 40mph, poor idle, hard to start.

I concluded the carbs were in need of cleaning. I took them apart and cleaned them. All is well, except I took too much apart. Best I can reference, one of the parts I removed was a factory preset, do not remove under penalty of it'll never run again.

Anyone have a reference for the presets on these carbs? I have been completely unsuccessful at finding them, or replacement carbs (GS550 or GS750 carbs).

Help?
 
Without enough details as to what exactly you are refering to, the factory pre-set for the idle fuel mixture is around 1.5 turns out( this is an air adjustment, farther out is leaner), did you check the points and capacitors? They sound more the culprit here
 
Are the carb papers still in The Garage? You may want to check these out. Maybe you?ll see something familiar and get the stuff back together again. It s hard to tell by your descreption what the problem is.

Arnold after all the education that you have, do you really want to screw up the English language by talking like Americans. :lol:
 
Preset

Preset

I recently disassembled and reassembled my '79 GS550L, including the carbs. Didn't touch the factory pre-sets, though. Do you happen to know which ones you changed? My carbs are back in the bike now, but maybe I can get to the part and figure out what it's set at on mine.

Well, it was a screw out brass piece that looked a lot like the jets. however, it wasn't, once removed. Hard to describe, and I can;t find a pic to illustrate.

The answer about airflow sounds very likely, and 1.5 turns would put it close to bottom, where I seem to recall it was. I just couldn't tell how close to bottom. :?

I replaced points and condenser first, thinking that would be it. I have recently replaced the coils too. I get nice fat knock you on your ass (really. Long story 8O ) spark from them. Timing seems good, too, but hard to check accurately when it won't run at all.


Added:
I looked at the carb guide in the garage here. It was so completely different than my carbs as to be near useless in my particular application. It is great as a general guide, however. Just not useful for unding my mistake.

Side note: What other bikes have these or better carbs that I can drop in place? (I am willing to remove the airbox and use individual air filters instead. I'd likely do it anyway.)
