    A note to new registrants...
    All new forum registrations must be activated via email before you have full access to the forum.

    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.

Cant get her run properly.

Its a GSX 750 ES -1983.I have change the exhaust to a Marshall 4-1.Rejetted Main jet to 125 (120 standard in Europe),raised the needle 1 step,Pilot screw 2 turns out.But when i ride it at full throttle the bike stops in acceleration for a moment,She dont rev up like she should.
What more can i do?PLEASE ADWISE!!!!
 
Pull the plugs and see what colour they are.
Black lower main jet
White raise main jet
After you get the main jet dialed in work on the needle then the pilot circuit (idle)
You may have to go up one on the pilot jet also.
 
Another thing to consider is your fuel level. Make sure this is within specifications. If the level is too low this could account for a lean condition.
You may also want to try going up a little on the main jet.
 
go 135 jet and keep the needle where it is if the 135 is a bit much lower the needle to compensate :D
