    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.

Hi,
I was just given a bike and the guy said you had to run full choke when it is cold out. Well today it was 69 degrees and I could only get it to start on full choke and it would run about 10-15 seconds and shut off. I checked the petcock like it said on one of the forums and it seems ok.I would guess that the carbs are clogged up and was just wondering if I should try to clean and rebuild them or have someone do it that knows what they are doing.Is it just a matter of teardown, clean and rebuild or do you have to do float settings and air/fuel adjustments and all that high tech. stuff ? I really appreciate any input. Thanks

It's a do it yourself thing, easy except there's four of them, you don't need a rebuild kit.

There's nothing high tech, this is a 1978 bike remember?

Here's most of what you need to know:

sea foam

sea foam

I just read somewhere else that a guy unhooked his fuel line from the tank and injected sea foam directly into the carbs and ran the engine off of it. Then he let the carbs fill and let it set for 3 days and reconnected the tank and filled it and started the bike and all his carb problems dissapeared and it ran great.He called it a cheap carb rebuild.Does this sound possible without damaging the plastic parts and o-rings and would it help varnish buildup or stuck valves in the carb?
 
Nothing beats tearing them down, but I have used the direct sea-foam feed method just to get a bike running after a sit. Sometimes you get lucky sometimes you don't.

It might depending on what's wrong in the carb. Won't fix tattered O rings or broken pilot screws. It really is a good idea to do it right so you know what's inside.
