Hi guys, a GS n00b here.  I picked up a 2006 GS500Fwith 5k miles for $500.

  The previous owner took the carbs, fuel hoses and vacuum hoses off about a year and a half ago and then never finished whatever it was he was going to do. 

In any case, I have the bike now and cleaned and replaced some gaskets in the carbs.  Set the floats to the proper height and checked the fuel height.  I drilled out the air fuel mixture caps and set them to two turns out (the left one wasn't even one turn out and the right was two out). 

So now I got the thing running but for some reason when I give it gas it stays at whatever RPM it got to.  So if I give it gas and it hits 4000 rpm it stays there.  The only way to bring it down is to turn the bike off.  If I then restart it it sits at about 1200 rpm.  Give it gas and it does the same thing. 

I have lubed the cables and checked them.  They return as they are supposed to.

Only thing I can think of is maybe a vacuum leak.  Any other ideas?  Do you need more info?

could a tiny crack in the intake boot keep it from idling back down? 

Yes.  Search "hanging idle".
