    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.

GSX 750 ES 1983,I have asked here before about yhe bike,And i have got plenty of tips.But now i am lost.I have checked everything,Valve clearence,New coil cables,New plugs,New plugcaps,Clean carbs,Checked float hights, diffrent settings of pilot screws,Diffrent main jets.Now i have 130 (stock 120).I have 4-1,New airfilter in stock airbox,BUT STILL THE BIKE HESITATES WHEN I WANT TO GO WTO,no matter whar gear i am in.PLEASE ADWISE:
 
Sounds like a jetting issue. Try shimming the needles and then learn how to do plug chops to judge the mixture at different throttle settings. There is lots of info in the archives on how to do plug chops so I suggest you learn to use the advanced search function.
 
I'm certainly no expert when it comes to jetting. But, it seems to me the the mains are to big. Perhaps someone else can chime in.:)
 
What RPM is it hesitating at?

Does it hesitate, then go?

Or does it just not go?
 
If you have NOT installed a jet kit, with ADJUSTABLE needles, with a 4 into 1 pipe, it will NOT run correctly till you do. Ray.

Click to expand...
pssssst jetting has nothing to do with RPM... it has everything to do with throttle opening... It could be doing the same thing at 2K RPM as it is at 7K RPM...just depends on WHERE in the throttle position it is..
 
Yeah, but a general assumption is that throttle opening is commensurate with RPM, is it not?

So, if he's wacking it open at 4K RPM, that's about 1/2 throttle.
