    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 all,

May be picking up a parts bike, and am wondering if it is much harder to clean out the older style GS carbs, and if the o-rings (robert barr) are compatible?


any help/tips would be great.

It's pretty sraightforward to clean the older ('77-'79) VM carbs - just keep track of the parts. Robert sells a set of o-rings specifically for them.

I used the carb cleaning article from the GSR garage as a general guide, did a pile of searches on the GSR forum for other tips on cleaning, initial settings, and final tuning, and had several manuals. It was helpfull to do a big blowup of the diagram in the manual that I hung above the bench as a reference.
 
My personal belief is the Vm's are easier to clean & take care of compared to the BS series
 
VM carbs are easier to work on than CV's. Barr's o-rings are recommended.
As always, a good manual, factory is best, is needed to do a complete job.
 
well. i wasnt planning on changing any of the settings (float height, air screw), but just cleaning them out and replacing o-rings.
