Engine is warmed up,,,,,
Crank 1/4 throttle(blip)and get a backfire(only one and then back to idle).
As above,,,sometimes an intake fire.




That sounds like a legitimate issue somewhere, not just the need for a larger pilot. Once it's warmed up, my bike never stumbles and never fails to respond sharply to a throttle blip. It only backfires occasionally during starting, and decel popping is minimal and subdued. Maybe the dyno run will tell you something.
