Thanks again.
I tried running the bike with the petcock in prime and I don't think I have a problem with fuel flow.
The bike runs excellent except for sometimes when the bike is fully warmed up, and its time to idle again, it stalls. Its usually at a stoplight after a good hard run, or when coming back into my driveway after a ride. I can't figure out why it just dies. The bike will restart with some throttle, sometimes stall again, and sometimes run fine after restarting. It will drive away just fine though.
The bike has a factory pro kit with 195 deg t-stat, 97 main/middle clip/2.5 turns on the fuel screws. Bike is stock other than a cobra f1 slip-on. Carbs are synched perfectly and when it idles the idle is strong at 1600.
