    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.

High Altitude Jet Sizes on GS650

Hey all, I've got an 83 GS650 shaft drive, I think it's the only one in existance, and no one makes a jet kit for it, only the 81-82s. It's got an aftermarket air filter with most of the airbox still intact. I'm going to put a straight through exhaust on it for the sound, not really looking for a performance enhancment, and need to know what size main and pilot jets to put in, and whether or not the needles will have to be raised. I called Dynojet to see what they say for the 81-82 bikes, and it appears either these bikes use different jets or Dynojet does, because they told me 155 mains, I currently have 105s. Any suggestings or starting points would be appreciated.
 
try http://chopperbuilders.net they had a jet size by # of modifications chart I saw somewhere.

keep us up on how it goes, eh? I've considered a straight pipe for the 850 I'm working on...

what part of CO are you in?

edit: looked on there and didn't find it, but I know I read an article not too long ago that had some sort of formula like

pods = +1 jet size
4-1 pipes = +2 jet size
straight pipes = +1

etc etc.,
then add up all the mods and subtract 1...

certainly don't use this as I don't remember the numbers, but just so you'll recognize it. it may have been on the forum part??
