    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.

got a 82 GS650 glz mikuni stock carbs but old air box took a crap went with individual KN type air filters what main jets should i use
 
stock size is..

stock size is..

110, just to save the trouble to opening up to look.
 
What are people with 77 to 79 GSs doing? K&N doesn't make a kit, but I found a seller on ebay that makes different sizes of main jets for these late 70s bikes. I have a vance and Hines exhaust with K&N pods going on soon.
 
Andrew, you can buy mikuni main jets for your 77-79 bike from your suzuki dealer or from many places on the web (crc2onlinecatalog.com, bikebandit.com, etc). My '77 750 has a Vance and Hines and pod filters and I ended up with 125 mains, and I am still getting the pilot circuit dialed in. 17.5 was too big, so I am back at the stock sized pilot jet (15) but with the pilot screw out an additional turn and I had to raise the needles 2 notches. Once the snow melts I will be able to test it out a bit better.
