    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.

Can you identify Mikuni Carbs, BS32?

When I purchased my 1980 GS1000G this set of carbs came along with the deal. I was told they were 1980 GS1000G carbs. Well they are not like my 1980 GS1000G carbs. Two things I noticed. One they are smaller, my guess is that since mine are BS34 these may be BS32. The other thing I noticed was that the spacing between 1&2 and 3&4 are like mine but the spacing between 2&3 are about 1/4" closer than mine. One other thing (I know I said two) the choke cable is clamp on where mine is bold on. Before I list these on eBay would like to have a better description of what they might be from since they do not appear to be from a 1980 GS1000G. Thanks

Those are off a 550 or 650. Measure the inside diameter of the intake side of the carbs and they should measure 32mm.
They will not work on your 1000.
 
They do look to be 1980 to 1981 era CV carbs based on the choke linkage, but I don't think they are 1980 GS1000 carbs. My reasoning is that the butterflies are marked 135 while my 1980 BS34SS carbs are marked 140 and my BS32SS carbs are marked 130. They should also have 4 openings on the air inlet side as apposed to the two on those. Measure the engine side inside opening and see if they are 34mm or something else.

No numbers

No numbers

Could not find any numbers on the carbs in question. I was able to find them on my GS1000. It has a set of 49150 - C033 on one side and 49150 - C034 on the other. Measuring the input with a steel ruler in inches and doing the conversion these carbs are 32mm ID on the intake side.

I am aware these carbs will not work on my GS1000, thus the reason to want to sell them. Can't even use parts from these carbs as the bowls, top caps etc are smaller than my carbs. Just looking to try to identify as best as possible for the next owner.
 
can you make the pictures smaller...please

say 800X600

would be much appreciated

Looks like Bill is correct.
 
Thanks for all your help

Thanks for all your help

Thank you everyone for your help! Pretty clean on the inside too. I have all the pilot plugs. I took them out thinking they may work on my BS34s in the background but no such luck.
 
I have 10 of those they look like the BS 32s to me and mine go with a 1981 gs550
