    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.

Okay, I've had this bike 5 years tried to sell it but no takers. Now I have fallen in love with it again and want to step it up. Here is what I have. 1984 GS550ES 25,000 miles Runs well. I bought it for $200.00 with busted second gear. I had the transmission gone through, new 2nd gears new shift drum forks, bearings seals etc. and it works like new. I purchased a set of Mikuni two-barrel carbs off of eBay and a Vance and Hines four into one pipe. I also found a pair of cams that spec out like new. Compression is 125 PSI across all four cylinders hot holding wide open throttle. Book calls for 142 to 199 PSI. I put a little oil in each cylinder and it reads 200 PSI across the cylinders. I adjusted the valves before I did the compression tests. For my first stage I want to clean the carbs that are coming and then jet them? and do whatever has worked for others with the jet needle setting, and put on the Vance and Hines.
How should I prepare the carbs. Come on Genius's out there Help......................!!!!!

Guess I should have read further on the Forum for my answers as in just above. New to forum so will search more before I ask questions :-) Tom
