    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.

Whats the major difference between stock needles or dynojet kit?
 
There is a much bigger taper on the DJ ones (i.e. the tip is much thinner) & the have moveable clip positions.

I have a GSX 750 ES -1983.Just mounted a Marschall 4-1,Stock airbox with new originaltype filter,Raised needle 1 step,Stock main jets is 120.Have change main jets from 120 up to 125,But it will still dont rev out properly at high speed.What to do? All carbs are cleaned with solvent and compressed air.
 
If you're running with the stock intake I'd advise putting the carbs back to standard settings with a Marshall and then doing plug chops. A Marshall pipe doesn't change things very much usually and you may be able to tune the carbs in fine with very close to stock settings. Plug chops will be the key though.

Plus check your fuel tap can deliver enough fuel at high speed.
