V111 Sputter

Hopefully blow the dust off this forum...

New V111 with 1500 miles. Came with SuperStock ignition and 585 cam.

I put on a new Supertrapp 2 into 1 with the tunable disks. Under power the motor purrs. Slight pop when I shift around 3500rpm, plus a good suck as the revs fall off. Wonder if I can do anything with the popping and slight jerking at 2200-2500 rpm when not “on the cam”. Idle is fine. Have not messed with the ignition, but I don’t think you can anyway. I do have a brand new DynaTec but wasn’t wanting to mess with a brand new motor.

Supertrapp started with 20 disks closed end and ended up with 10 disks open end.

Anyone have experience with this exhaust and EVO?
