Trinity 2 into 1 jetting issues

[echatman]

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?

Rich on the pilot and the main is important. Put a 42 pilot in it and report back. If the main is too big it's going to bog at 1/2 throttle.

And it doesn't bog at half. It's wild at half. Only hesitates/misses at idle-1/8.

42 pilot should fix it

Good call. I have DEK, EEK, and EEJ all to experiment with.
