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.

  • 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.

Can't get bike to start/idle

Ok, this bike is new to me. I bought it as a project bike, its an 82 gs1100gk. when i took the carbs apart there was stuff stripped out and jets clogged and everything else, so i took em to a shop and they rebuilt and dipped em. supposedly they have it set up so i just put em on and the bike will start. I have checked my spark, it seems like im getting fuel and there is compression.... i am lost, i put my hand over the back side of the carbs when it was cranking and it sucked my hand in and it started... then it died. I hope this makes sense to some1 but i am so high on gas fumes right now i dont think im making sense...:confused:
 
If you're putting your hand over the back side of the carbs, then you probably don't have your airbox installed and tight. The carbs depend upon that restriction to help induce vacuum and pull fuel into the airstream.
 
well i went back out to the garage and tried putting the airbox back on.... nothing.
 
Obviously you're running lean.

Did you put the airbox back on WITH the air filter? Check the condition of everything: make sure the airbox boots have no cracks. Did you check the o-rings to ensure they are in good shape? If you have any air leaks at all from a stock system, you will have trouble running.

Are you putting on the choke when you're trying to start?

How far out are your idle screws?

Since you didn't clean your own carbs, you will get suggestions to clean them yourselves: and I would do that. Did they replace the jets and other internal parts with OEM parts or those from the commonly-available cheap rebuild kits? The latter are reputed to frequently be of much poorer quality/tolerances than the original stock parts. The stock parts rarely ever go bad; just need cleaning is all.

Also, have you checked/adjusted your valve clearances yet?
