    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...

    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.

are these carbs the same? i have the 79 and dynojet only makes the stage 3 jet kit for the 80 gs750. will this jet kit work in my 79? thanks.
 
No they wont. The jets for the DynoJet kit are gauged off of the BS32SS carbs, and the set up for them. Your carbs (VM26SS) have an entirely different set up. You CAN however purchase the main jets that you will need to jet for whatever it is you are jetting for from Z1Enterprises.com. You will need to figure out what size of main you will need, and the jet needle will likely need to be moved as well. In YOUR carbs, the needle comes with adjustment range, whereas the BS32s do not. Basicly, you can jet your carbs by hand, once you figure out what size main you need and where the needle needs to be.
 
thanks a bunch cafekid, i am running k&n pods with a vance and hines exhaust. dynojet called this a stage three setup. the pods and exhaust both came with suggestions for jet size but im still not sure what size i need any idea how to find out?

I am currently in the process of dialing in nearly the same set up on my 77, which would more or less be the same bike as yours. You're going to want to try sticking with the stock #15pilot jet, try a 127.5 main jet. I have moved the needle in mine, but think i will need to move it back. So try leaving yours in the stock position. I will update further on my findings, as its running pretty good with my set up, but not quite perfect yet.
 
thanks, ill check it out. the carbs were jetted by the previous owner for the kerker exhaust that i replaced. so im not sure whats in there for the main jets right now. keep me posted and ill do the same.
