    A Special Note about Email accounts!
    DO NOT SIGN UP USING hotmail, outlook, gmx, sbcglobal, att, bellsouth or email.com. They delete our forum signup emails.

    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, so I ordered the manual for my bike, a new set of rubbers for the spark plug caps and talked to the local shop owner.

Still got a funny bogging ad 3500 to 4500 RPMs Can't figure out what's wrong with it. So I tore apart my carbs yesterday. First time I've had to do this on this bike.

OK, first of all, the left carb (86 550s have 2 two-barrel) was leaking out of the boot going to the airbox. the left one seemed fine.

When I took it apart, the first thing I noticed was that the RIGHT carb had the float needle in upside down :confused: .

So, basically, someone didn't put the carbs together right, and there could be anything misadjusted on them.

What I'm looking for...

1)float heights
2)jet size (2 main & 2 pilot in 1 bowel)
3)slide needle height
4) anything else pertinent
