Loss of power at higher RPMs

I just got new tires and the carborator cleaned and she was running smoothly but backfiring all the time when I let off the accelorator. Now about a week and a half later she feels like she's running on one cylinder or something. it doesn't get up past about 5k RPMs and feels very sluggish. First gear seems to be relatively the same but once I get into the higher gears it has major loss of power but still runs and shifts. Any help would be much appreciated. This is my first motorcycle and I have no idea what I'm doing.

Who cleaned your carbs ? and was it running good before being cleaned ? What year and model of bike ? Without that info i would say you've got possibility of a few things. 1) clogged jet 2) floats are out of wack 3) Carb isn't adjust correctly ( idle screws). In my experience backfiring means it running to rich to much fuel. maybe try turning your enrichment screws in (usually leans out mixture check owners manual).
