    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...

    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 really strange problem w/ a GS550

I have a 1981 GS550T with a really wierd problem. My problem is that the bike runs perfect (I mean perfect no rich or lean condition) under 5000rpm, but after that the bike dies and doesn't increase in rpm at all. For anyone who doesn't know much about this bike, it has the constant velocity carbs and a 4 into 2 pipes.
 
rev limiter

rev limiter

It almost sounds like a rev limiter but I can't imagine that your bike would have one of those!!?? :roll:

Sounds to me like the timing may be severly retarded.

:D
Could it be you have fuel starvation? Enough fuel to run up to the 5000rpm point but no more. Remove the hose off the petcock and turn the petcock to the prime position and see if there is a good flow. Use something to catch the gas in. If one of the carbs float was sticking then the engine would run roughly. I cannot imagine all the floats sticking.
Just a thought.
:D :D :D
 
Once while messing with Karen's bike I ran a screw in that I didn't know what it was. Turned out to be the high end throttle stop, it worked some what like a rev limiter, only could get about 3/4 throttle. :oops: Had to fix that fast she hated me, rode it to work and back that way. :twisted: Just for fun check on the carbs where the cables hook up, pull her wide open and see what it hits. Safe Riding, Bill
 
Yes Check for full throtle operation. Could the muffler be pluged??
