    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.

gs 850 won't run past 2200 rpms

Ok, I'll be the first to admit that I'm new to this whole motorcycle addiction, but this one shouldn't be this hard. I have an 1981 gs850l, and it starts but does not run past 2200 rpms. I checked the barrels in the venturi and have the carbs set at manual recomendations before being synced. IN order to start the bike i have to have the choke pulled full,and then it will fire, and run up until 2200 rpms, sometimes back fire, and die. Also any aggressive throttle movements and you find instantaneous dead engine. What's my problem, is it just carb synchronizing? help please.
 
Have you opened up the carbs taken out the main jet and looked for crud in the main jet, as well as the needle jet? It sounds like they're clogged up. Carb sync mostly effects idle, so it's probably not that.
 
Are you running it with the air box??? will not run right without it
 
Exactly what my bike did until I cleaned carbs. After that bingo! Bike doesn't run worth crap with airbox and filter off. 8)
