One cylinder dead without choke

[DannysZ28]

I just picked up an 06 banshee and it has fatty pipes, pod filter and boost bottle. Other than that its stock. The problem is at low rpms, it seems like one cylinder dies but will start back firing if i pull the choke. After the rpms get higher the cylinder will start firing and will run good through out the powerband. Im at sea level, plugs look good and compression is 120 on both sides. Its running a 290 main and 25 pilot

The pilot jet in the carb on the cylinder that dies out is probably plugged up. You will need to clean it with a small strand of stiff wire and some carb cleaner.
