After Installing my FCR I had started with a 42 pilot jet. I turned my fuel screw all the way in and it didnt kill the motor out so I went down to a 40. I turned my fuel screw all the way in with the same results. So I special ordered a 38 Pilot jet and now if I am bottomed out on the fuel screw it slows the idle slightly, but the idle doesnt change after half a turn out. It seems insane to drop to a 36 pilot jet if one is even made. I have the new Pilot Air Jet from the rebuild kit, and I just today ran carb cleaner through and blew compressed air through the Pilot air jet Circuit to make sure it is cleaned. I droped my NCVQ needle down the 5th clip and still the same results. I am running a 158 main jet and the plug looks tan. I ride at about 4,000 feet elevation. I read on TT about people with DRZs taking the PAJ out completely, but havent tried it yet.
