I just rejetted my carbs and I think that I put my lines on wrong. It only runs on prime. If anyone could post an exact routing of the 01-up carbs that would be great.  need routing for all the lines, not just the ones coming off the gas tank.

I see that there is a fuel house routing diagram for the 89-00 GS500 carbs on Kerry's website, but none for the 01-up carbs. Somebody should make a how-to for the newer carbs.

If it only runs on prime you probably messed the routing of the vacuum line. There should be a thinner hose coming from the top part of one of the carbs (I assume it's on the inside of the left carb as well), connected to a nipple probably on the inside of the petcock.
If that hose is not connected or quenched the petcok does not open when the motor is running.

Just to make sure: RES doesn't work either?

I did hook up everything OK, but what I didn't notice was the big A$$ air bubble sitting in my ON line, it wouldn't allow fuel through. The bike sounds frickin' mean though. That V&H Pipe sounds wicked. I have yet to ride it since we fixed it, but my friend rode the bike for test purposes (he is a bike mechanic) to find any jetting glitches and he said it runs like a "raped ape". That made me feel good, it means that this forum gave me the perfect jet settings.

I forget the jet setting to be honest, I will check them sometime.

I have one last concern, there are two line coming off of the carb (both are on swivel joints, and I want to make sure I ran them to the right place. I ran the one on the bottom of the carb to the left side of the frame-mounted petcock, and I ran the top one as a vent and left it hanging on the outside of the case.

Does this sound right?

THANKS, BigTwin

Unless they changed dramatically in 2001, the bottom should go to the fuel, and the frame-mounted petcock should be connected to the left carb. 

Edit: that was completely unclear.  The bottom should go to the fuel delivery part of the petcock, ant the left carb connection goes to the vacuum diaphragm.
