CCW tha Heist

[Tacoma]

I have been riding my heist every day for the past month or so and it is a blast and runs like a champ normally. Just yesterday I started having a few issues with my bike just dying out while coming to a stop or stopping at a stop light and can feel it idling real low right before it dies out. When it dies I start it up with a little rev and keep on going. I have messed with the idle, cleaned out the carb and just today drained all the gas and cleaned the petcock making sure there was no contaminants. I was hoping some of you heisters can help me out a bit with pinpointing the problem. I recently added a new race carb by weaver rides and G&D exhaust and not sure if that has anything to do with it. Has anyone had anything like this happen with their heist? I would really like some input. I will be changing the oil tomorrow to see if that helps. Any suggestions on oil? Please let me know of anything I can do to fix the problem. I love this thing and might be thinking of selling it if I can't get it squared away. Please, any help would be great.
