    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...

First this sight and the advice passing along here is excellent. :lol: :lol:

Secondly, to the problem at hand.
BACKGROUND: the bike is a 1980 gs1000g. when i picked the bike up it ran rough and when you laid on the gas it would fall on its face and then run like a bat out of you know where. when i popped the bowls to check the jets etc. i found that the floats were way off flooding the cylinders and the jets were different sizes. :?: the part for the float pins were broken, a real mess in there.

i needed carbs so i picked up a rack off an 83 gs1100 from a local salvage yard. thay needed cleaned so i cleaned them. i put them back together and it still runs like poop. the carbs had 113 jets in them so i put 115 jets in and still poop. :cry:

HERE'S WHAT SHE DOES: the idle is okay and it'll rev to around 4000rpm in nuetral no load on motor. then it boggs down and will die if i keep throtle open. (kinda like it's not getting enough fuel or somthing)
i have not touched the factory set mixture screws (they have probably been monkeyed with by a previous person)
please advise on what to do next. i'm at my limited whits end

thanks for the help in advance

Sounds like you are starting to run lean...more air flow but not enough gas due to either the needle being in the wrong position or the main jet is undersized (or both).

Waitaminute. Are you running the stock airbox or pods or what?
Cause I thought those carbs came with stock 107's in them.

115's are going to need some sort of aftermarket filter that flows more air to compensate for the increased fuel flow if those are not the stock main jets.
