    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.

smoke out of #3 carb

ok cleaned carbs and replaced petcock yet still leaking gas out of carbs o so slowly. no drip or anything like that but you can tell it collects towards the pods...normal????........rejetted with dynojet kit fired it up and it went crazy finally got the idle down and when i shut it off i noticed smoke coming out of #3 carb with filters off. what is the freaking smoking??? anyway new rack of carbs on the way just trying to salvage the ones that were on the bike(think im gonna go back to factory everything when they get here)...any tips, points or help is greatly appreciated...by the way its an 81 750l
 
Was the smoke white? Was there a heavy fuel smell to it? It is likely that the engine stopped with an intake valve open and what you're seeing is a vapor exiting through the carb. This usually happens when two things are going on, you may be running rich with the new jets, and check the valve clearance.
 
i dont doubt the rich part, i'll probably pop the circlip up a few notches to hopefully lean it out.as for checking valve clearance???? clueless in that dept....cant really tell if smoke smelled like gas bc my hands already did so the aroma was in the air before this happened
 
How many miles are on the bike? Was it in running condition before all the mods? If you go back to the stock airbox, you'll have to rejet (down size) for sure. As far as checking the valves, if you haven't done so yourself, I would strongly suggest it. They should be done every 7-10 thousand miles.
 
the bike says 10k but it could very well be 100 if the speedo doesnt go that high...it was running well before the mods . when the other rack arrives im going to put everything back to stck and start over to see if i cant isolate the problem. if not ill sell the beast as a parts monster
 
Meeeeeee........I'd put it back to stock and ride a very nice bike! Mods are great, but it is a whole different game. I've always got one on the ground that I can ride whenever the weather allows, one on the table that is a work in process (currently a three year process...don't ask) and one in the wings, waiting for a direction to head. The GS is a very well designed bike, maybe the best in it's day, and to have an original in great working condition, is a tribute to the design, the owner, and everyone else out there, who knows what the're looking at. :shock: :-D
 
lol ...true very true...i have all the OE stuff i.e. air filter/housing sitting aside i just wanted to see if i could give her a boost, i mean after all im going to school to work on these things for a living. i guess ill return her to stock and concern myself with more pressing issues of aesthetics....thanks for the advice even if it wasnt what i wanted (yet needed) to hear :-D
 
i washed her haha.... a little

No problem...the older I get, the more I sound like someones father...HMMMM....mine maybe? :-D Great looking bike there, work on a new seat, a few of the smaller things, and you'll have a winner in anyones eyes!!!!!!!!


The GS L models are sleek and sexy right out of the box!
