I've look and looked and I've only seen information on the older carbs. I have an 04 gs500f. I am doing a rejet. I started a couple of months ago and have had it apart. I'm trying to remember how it went back together. 

I have The 147.5 in the bottom jet(as pictured) and the 60 in the one above it and the 20 next to it. I added a washer under the needle like I have read. I wonder if it is thick enough(0.5mm) should I add more?  Is my setup right?



Also what is this? And can I remove it from the vacuum system?



Thanks for your help

Don't forget to drill out the brass cap for the fuel screw to make it accessible.  It's the brass plug nearest the top of your picture, the one that juts out from the bottom of the carb body.  As for your jetting specs...I have not a clue, mine's an 01'

Yes the jets are correct. That bottom one is the main, the one above it is the mid, and the one on the right is the pilot.
The cap you need to drill out is the one on the top of the pic. Not the one just below it.
Cool.
Buddha.

see the brass plug above?   Drill that out CAREFULLY and it will expose a screw under it.  Thats your mix adjustment screw, you'll need that to fine tune the mix after. 



Other than that, the jets are in the correct spot.  Make sure on the main jet you didn't forget the o-ring that sits between the jets. 

While you have it open, make sure the float is within spec. 

Thanks guys. I have drilled out that brass plug since I took this picture. I just wanted to do it with the bowls on to keep the shavings out of the bowls. Does any one know if that vacuum filter can be removed from the system? I am trying to clean up all the extra vacuum line I can.

A .5mm washer should be sufficient. 

Ok I got the brass plug drilled and the mixture screw set at 3 turns out. Once that was done I put everything back together.  I reinstalled the carbs and hooked up a temp tank I made. I got the bike started. I noted a small fuel leak from the right carbs fuel bowl. So I got to take it all apart and figure out what's up with that.

For those of you who are running a k&n lunchbox what do you do with the two black ports above the brown fuel inlet.

After some more reading I am pretty sure those are just vents/overflows.

So my next question is how do you "properly" set up the Throttle position sensor? It has some adjustment on the way it mounts and I am not sure what direction does what  and how best to set it. It doesn't seem adjustable once the carbs are on the bike.

Is it possible that my fuel leak is from where I drilled the brass plug out to get to the screw? That is where the fuel seems to be dripping from but that is also the lowest point so it could be leaking somewhere near it and running down to drip off of it.
