    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.

I picked up an extra set of carbs this weekend as a spare set. When i got to checking them out i noticed some numbers imprinted on the butterfly's. The carbs that came with my 81 550L say 140 on the butterfly's, the carbs i got (supposedly off of a 80 550E) say 120. I didnt think this actually mattered, but wanted to verify with you guys if there was a difference, or are they just numbers.

TIA, stephen
 
Checked my carbs again and i was mistaken. The 550E carbs say 125 the 550L carbs say 140.

As for that link, i checked against it and it shows from the early 80's era that all 550 carbs were the same.

I just wanted to ask and see if one was actually smaller, or if the numbers may just be pointless.
 
The Numbers Are Pointless Just Make Sure The Carb Bodies Are The Same, Measure Both Opening To Compare, Then Also Compare All Internals To The Stuff In The Carb Post To See What You Have.

The Engine Side Of The Carb Opening Will Be The Body Type (ie Opening Is 32mm Then Its A Bs32) You Will Find Many Different Bikes Used The Same Bodies But Had Different Internals Thats Where The List Helps. So You Can Zero In On What You Have And What You Need.
 
Thanks for the help man. I'll grab a set of inside calipers and measure up.
