DAMMIT!!!!!!!

Looking at your diagram, does the fuel supply from the petcock go to the lower or upper "T" on the carb?

Looks like the upper "T" is for the carb vent line that goes above the carb body and over the airbox.....is this correct?  And the fuel supply goes from the petcock to the lower "T" on the back of the carbs?  is this right?

I have an eery feeling that these lines might be crossed,.......

Well, from looking at it in the dark garage, I think that is exactly what happened!!!!    The P/O must have put these lines back on wrong and couldn't get her started.  When I looked at the bike, I put a jumper box on the battery and sprayed some starting fluid in the airbox and she fired up briefly, so I bought it.  When I took the carbs apart, I never even had the thought that the P/O had incorrectly routed the lines and I re-assembled it like it was each and every time..............


Hopefully (fingers crossed) this is the case, I will find out tomorrow.  If that is it, I owe you a beer or three for pointing out the obvious to me 

Upper T = carb vent
Lower T = Fuel input

  Hopefully this is the issue.  Should be up and running tomorrow if this is the case.  I will let you know in the morning.

If those were reversed THAT is what is flooding your carbs. You can know the difference easily because the vent is just a rubber T-thing whereas the actual fuel input is a more sturdy plastic. Consequently, the fuel input is usually harder to rotate.

Well,  That was the main issue.  I switched out the lines and put it all back teogether and fired it up.  Now I have to deal with a high hanging idle (around 5000 rpm's).  The throttle cables don't appear to hang up, and the manifolds appear to be in good shape with no obvious cracks.  I have stock jetting and only have the fuel screws out 1 1/2 turns from seated for starters.  I am hoping that it's just a really lean condition with the fuel screws at this point.  i will turn them out to 2 3/4 turns to see how much of a difference that makes.  i will probably hit Buddha up for rejet kit so I can run a bit richer.  All in all, It runs now which is 100% better than when I bought it! 

When I wrenched for a living, far too much of my time was spent undoing something that somebody before me had done that thought they knew what they where doing
(say that 10 times fast)

Usually 3 turns is good. That's almost certainly your issue.

One other suspect issue is the absence of and/or worn out sync port o-rings. Check those if you can. Shouldn't need to remove the carbs for that.

What the hell is a sync port o-ring?  And where is it?

It is the small oring that sits under the black plastic diaphragm cover.  It seals the small opening that have rubber caps and clips that is used for syncing the carbs.

Here's a diagram:

Just noticed you have a 01 GS and above pic was for 89-00 GSs, the 01-02 models are the only GSs that the fuel lines from tank to petcock crossed.  There were 3 different petcock styles over the years.  If you connect the fuel lines like the pic shows you are going to switch to reserve one day and discover you have already used the reserve fuel. Don't ask me how I know, I have a 02 GS.   

IDK if it helps but..

My tps is umplugged, the float covers w/ the vac lines are plugged, and will be replaced by black tops eventually, and anything emissions related is removed.

This allowed me to do the ignition advance without the newer electronics kicking in and stopping it.

The tps shouldnt do anything to hinder starting if its unplugged or mission, because the bike will go into the standard ignition mapping, not the "smart" one

Thank your sir, I am putting her all back together today and hopefully riding her into work for the 1st time.  Still waiting to take delivery of a new OEM front tire to spoon on for inspection.  I will be turning the fuel screws out to at least 3 full turns to assist in the lean condition until Buddha gets the restock of the bigger jets that I need.
