    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.

Choke on = very high idle @ around 7+k rpm
Choke off = same conditions
Choke in the middle = random idle surge from 1.5k - 7+k rpm

I assume carb issues. Anyone have a suggestion before I tear into the carbs?
 
Hi,

I would suggest tearing into the carbs. :D

But seriously, here is the procedure... http://www.thegsresources.com/gs_carbrebuild.htm

A complete disassembly of the carbs and dipping of the carb bodies and other hardware (for up to 24 hours) is usually recommended. Then reassemble with an O-ring kit from http://cycleorings.com .

And be sure your air intake system is tight with no leaks. This usually means new intake boots and intake boot O-rings, tightly sealed airbox (we just use weatherstripping these days), and maybe even replace the boots between the airbox and the carbs. Then all you'll need is a valve adjustment, a carb bench sync, then a carb vacuum sync, make sure the cables are lubed and routed correctly, etc. Of course, this is all assuming that you have the stock airbox and exhaust on your motorcycle.

Forgive me if I state the obvious.


Thank you for your indulgence,

BassCliff

That's pretty much what I was thinking. It doesn't have an airbox right now either. It has pods. The other 450 we got has the airbox and I'm going to put that on it but I don't imagine that would make it idle like that. Sounds more like a passage stopped up somewhere.
