Just be sure there is no air leakage across the carburetor insulator gaskets, and you should have it right. At the end of the soaking exercise you should blow out all of the passages with compressed air, because if you don't some of the gunk will still be there and will re-solidify, especially in tiny or blind-alley passages.
It sounds as if you have it pretty right. The final check I like to do on carburetors is to slide a jet drill of the size given in the specifications, through each jet, outlet and seat that has a specification. Don't twist the drill bit, just ensure that it will slide through with that slight drag that signifies a size-on-size fit. The purpose here is not just to verify that you have the jets etc clear - it is to see if there is any residue still in the carburetor. If you have residue in those specified places, you have it everywhere.
Life isn't normally this hard with carburetors, it just seems that the Mikuni used by Suzuki is something of a lady-dog when it comes to cleaning. However by all reports it is a very pleasant engine once you've got its carburetor cleaned out.
