    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.

Fuel system check: 77 GS750

Thanks Chuck!

I've got the cams off now to clean some rust. I'll set timing when I reinstall them using the manual's method of lining up the T mark behind the contact breaker and setting the 1, 2, 3 marks on the cam gears.

Bottom pilot fuel screws: 1 3/8
Side pilot air screws: 1 1/2 to 2
Vacuum sync (use main idle screw to keep idle steady as I adjust each carb)
highest idle method using the side air screws
 
WAY to FAT on the bottom pilots!!! 3/4 to 7/8 max. 3/4 is about where they came from the factory and 7/8 is just a tad richer...which isnt a bad thing as these bikes came on the lean side for EPA regs back in the day. At 7/8 they are just about right as far as not being overly rich or too lean that youll burn up valves or pistons.

As was mentioned..you set the bottoms and leave them alone. The 1 3/8 I mentioned is the side MIXTURE screws. When tuning the MIXTURE screws are all youre adjusting...follow????
