When I had my 03 I had T6s on it with the 280 mains stock pilots & after market needles/ toomey perfect jet kit, with K&N filter with modded lid 1" holes drilled with filter plugs. the jetting was pretty good for mine should be close for yours. /While you have your carbs off clean them real good, all jets make sure you blow them out, especially the pilots those things clog easy and be careful with the floats handle them with care; dont bend, dont drop,ect and if you figure it out check the float adjustment. air mixture screw start with 1 1/2 out from very lightly seated; screw in untill bottoms out/then back out 1 1/2 turns, that should get you a good start.
