    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.

OK, OK, OK... I give!

Unlike auto carburetors, side draft carbs of any sort do not flood with repeated throttle input. They require the vacuum produced by the engine to draw fuel through the jets into the combustion chambers.

Well, automotive carburetors "require the vacuum produced by the engine to draw fuel through the hets into the combustion chambers", too.
The difference is not in the side-draft vs down-draft carbs, it's in the accelerator pump.

Some bikes have side-draft carbs with accelerator pumps, you can definitely flood them with repeated twisting of the grip.

I have an '80 550L and this sounds like an intake manifold leaking o-ring problem. You can search for that or ask, but it might be a major air leak. Have you checked or replaced your intake manifold o-ring gaskets?

Intake Manifold O-ring gaskets... Guess I need to do some more reading
 
Found it!

WOW, I hate to invest more money in this thing...lol

Just bought it to make a few bucks. Have enough projects to keep me busy for years.

I made sure to clean the choke passages real good.

Got new plugs and getting good spark.

Well, airbox is installed but the airbox boots ar enot on all the way. Fought them for over an hour with lube and all and can't seem to get them back on. Figured I would get something even if it ran rough.

Yes, all of the pipes are getting hot. I figured she would run rough because I need new filter and air box not sealed up well. I have never ran into a bike that at least would not run when giving throttle. Although it would normally run rough but at least start.

I used spray cleaner and air. Same thing I have done about a thousand times on other bikes? Am I missing something as why dip only and not spray?

disassemble the carbs and dip them in carburetor cleaner. Spray cleaner won't clear carb passages very well. Clean ur carbs well, and it'll run
 
Anyone have a good source for intake boots? I know where to go for the O-rings thanks to BassCliff's website. Maybe buy new airbox boots too depending on prices.

Gonna pick up some carb dip tomorrow and pull the carbs again. While I have them out I will check boots and all real good.

Any secrets or tips on getting air box boots onto the carbs with them in place?
Click to expand...

I rubbed a very thin smear of axle bearing grease around the inside edge of the boots. The carbs just slipped right in once it was lined up.
 
Well, I went out this morning and sprayed some ether around the boots and she fired right up for a moment. Obvious the boots and o-rings are shot. I can see cracks up against the mounts on the intake boots.

So, where is a good source for new boots?

Anyone interested in buying a nice looking GS550L project?...

Hi,

There's a large list of our favorite vendors in your "mega-welcome". Shop around a little for the best price and best shipping. If you can't find your "mega-welcome", just click the link to my website (in my sig) and go to the REAE ME page.


Thank you for your indulgence,

BassCliff
 
Thanks Bass and I did look around but no luck on the boots themselves.

No matter though.

I want to thank every single one of you for the much needed help. Guy stopped in today and made me an offer I couldn't refuse so I sold the bike as-is. I told him about this place and wrote it down for him so maybe he will stop in. Seems to really like the GS's.

You all are welcome over to my place anytime!

Again thank you and keep the rubber on the pavement!
 
Well, that's good for him. I think he was trying to flip the bike anyway, and getting frustrated.

How do you obtain a small fortune fixing up old bikes? Start with a large fortune :lol:

Ain't that the truth Mike. I actually buy and sell a lot of bikes and fix up a lot of 70's model bikes. Mostly Yamaha's and Honda's though. I also part out older bikes if they are beyond fixing or no title.

My passion is building bobbers and choppers though. Got this one cheap and thought I could make a few bucks. Sometimes we lose...lol

oh, and for the record... never make a fortune with old bikes...lol
