Lean running midrange could easily cause bog due to insufficient fuel, needle not lifting to let enough fuel in. A plug read will help. If it isn't sooty, LIFT the needle.

Startling point is whether the carb and jetting is OEM. And are you getting lots of popping/backfiring on deceleration - this means lean, not rich.

Is this the original carb???
