    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.

Should be BS32 carbs I think. The ones in the first link are for a 79 or later. 80s had CV carbs..the ones inn the second link should be then right ones.

Thank you!!

Here you go, there are 3 sets around the same price. But wouldn't an 80 be CV carbs?

Edit: Yes, this.... https://www.ebay.com/itm/Mikuni-Carburetors/263397828395

I just got a set of BST38s on ebay for $25. I don't need them but couldn't pass it up.

Is there any real reason to switch to the OEM carb? My only hesitation is that the hitachi carbs on my bike have been jetted already and appear to be in good condition
 
First thing is that the Mikunis were designed and engineered to make your bike work and perform optimally. Second, has your bike ran with the Hitachi ones???

Since you are building a cafe I assume that means a modified exhaust and pods right? Given that, you will have to play with jetting regardless of what carbs you use. For a stock bike using the airbox a set of stock Mikuni's would be the easiest way to assure the jetting is correct. Those Hitachi's may be fine all things considering but just plan to do some jetting work before the bike is running the way it should.

Functionally, you could make almost any carb work, within reason. However, almost nobody on this forum has experience with Hitachi carbs on a GS, so we could only offer general suggestions, and they will have to be based on your observations. If you had Mikuni BS32 carbs, we could say "try this as a starting point". With the Hitachis, we don't really have a clue.
