    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.

I have Been running my 77 gs 750 for a few years now with a light1/8 throttle stummble. After tooling the form I desiced to tinker. K and n filters and x pipe exhaust. 125 main 27.5 pilot one notch down on needle....now when I choke to start no luck. Will start with some throttle but when I choke it she wants to die. With 122.5 main and 17 pilot choke worked great but had the stummble.. I know that there r 3 settings for the 750 based on the motor number. my is 16xxx carbs are not original and I don't know the motor number from wich them can from. would that make a difference. are the body's the same just different jets?
 
That is way rich on the pilot. I'd go back to the original settings you had and tinker with the pilot fuel and air screws to try and eliminate the stumble.

I had a similiar stumble and found leaning out the pilot circuit a little eliminated it.
