    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.

I have a 1983 suzuki gs650 twin air cooled converted into a bobber. No mods have been done to the engine. When the bike is idling the right carb/cylinder run the bike. The left side exhaust pipe is luke warm at best, while the right side is hot as it should be. If i put my hand over the left carb, The bike revs up a few thousand rpm. The left side fires and has plenty of compression. Also there is fuel getting to the cylander. vacuum leak? carb completely out of adjustment? or am i dead in the water? Any input would be greatly appreciated!
 
Let me guess, it sat on the side stand for a long time?

What maintenance have you done so far?

And which engine is it? GS650 is not a twin.
 
Left side is leftside as you sit on bike ??? OK, seems your left carb has plugged idle circuit and/or misadjusted idle/air mixture screw (the idle circuit gets plugged up real easily). Have you clean the carbs recently?
Are you still using a vacuum operated petcock connected to right carb?
 
Check the plugs on the left side. If plug is wet with fuel, try sucking gently on your vacuum tube.

If fuel comes out towards your mouth, petcock is dead.
