    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.

A conflict of information maybe???

I was checking on the stock jetting for the 78 GS 750E. When i got the bike it had the V&H 4 into 1 exhaust. I have since out on the stock exhaust. It runs pretty good but i had never taken a gander at the jets although I knew I had to at some point. Today I got the luxury of some spare time to pull the crabs and take a look. I went to the sticky looking for the charts and camem up with 2 that have different info. One goes by the engine number and the other chart just has it by years..Take alook and see what I mean...Is it the 100 mains and the 15 pilots..OR..the 97.5 mains and 27.5 pilots??? Stock engine and stock pipes. It currently has the 97.5 / 27.5 combo setup. 5F21 needle... clip in center groove.

Chuck,
I would go with the engine number specs.
This is probably one of those 77 registered in 78 type of things. Not having the original exhaust may make the change invalid anyway, so either may work would be my guess...:)
 
Andre..its a true 78 750 E. 618th one built according to ozebook.com. Engine number is 14820, so if i went with the engine number specs they are stock setup already and that means that the PO obviously hadnt rejetted with the 4 into 1s on her.

Here she is with the 4 into 1 V&H. All i have done is cleaned it up, carbs and valves done, and repainted her the same color. Then i replced the 4 in to 1 with the stockers..
