Trinity Stage IV 2 into 1 with airbox adapter, lid off and k&n. Fresh build with zero loss on leakdown test. I have tinkered with every combination imaginable. Starts easy, idles great, slight hesitation/miss off of idle. Rev a little and it runs like a raped ape. Here is the difference in my plugs.
Currently at 48 pilot, EEJ needle second clip from bottom, air screw 1.5 turns. Have only ridden it from idle-1/2 throttle. Not concerned with the main at this point, only the hesitation. Almost sounds like it's missing until i build the rpm's just slightly.
Am i rich or lean? Why the difference in the two plugs? Plug with no color on the base is stator side.
Tried swapping coil plugs. Any ideas?
