    A Special Note about Email accounts!
    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.

So 1978 gs750 pods and 4 into 1 mod

check float bowl level
order new o rings from cycle o rings
order new intake boots
order new float bowl and top bowl gaskets
replace main jets with 117.5 and adjust pilot? May replace with 17.5
have valves checked

use tutorial I found here along with some carb cleaners and rebuild carb and attach mods

any recommendations? I'm still unsure of how vm carbs pilot's are better and don't need replacing
 
With my 78 gs400 I ended up changing my needle jet, pilot, and main jets on my bs38s. Kept the stock needle size but adjusted it's position. Runs great! Go rich and tune down. Snap testing, high gear pulls, popping while decelerating, even the idle mixture screw setting, applying the choke while riding, these all will tell you which direction to go, just use baby steps. Don't go in, change a bunch of things. I think this part is just as fun as building the bike.
