Considering how much time you're spending messing with this bike have you considered going to a shop with a dyno and doing a few runs. They will have a wide band sensor and can actually tell what's going on with jetting using science (vs seat of the pants feel).

I misunderstood something I read. After capping the plug on the top of the valve cover, the backfiring has been eliminated.
We do not have a dyno on the island. No local shops specialize in tuning. This is all me.
