    The starter clutch / stator will have nothing to do with the ignition timing on this bike...and it's highly unlikely that the timing is off unless the signal coil plate fell off. Be happy it fired, but beware of a big charger gizmo, an electrical surge can fry your ignitor. Your carbs need thorough cleaning,so no sense looking for something else to blame.

      Well do the pod filters provide any advantage or are they just for looks? If not I'm going to go back to the stock airbox. Someone also installed a 4-1 header which i heard does bump power a little bit but that's going to stay stuck on there. I tried doing a quick search o whether anyone has a reference for jet sizes but I couldn't find anything

      Spark plugs are sparking correctly. Looks like it's time to clean the carbs finally.

      At least they aren't as hard to remove as a Honda V4.

        Here's a stock jetting chart..



        Done right, decent pods will give you a performance plus, probably at a little sacrifice of low /midrange. If you had the stock airbox/ filter setup, it would be easier on you to get it running nice.
        take the carb's apart and note jet sizes . Beware of geniuses that drill out jets on their power search!

            I thought you guys might be interested in seeing what trash i found while removing the carbs.

              Additionally, the choke was not set correctly (the screws did not like up with their recesses) The throttles were closed solid at idle. Is it like that stock? I'm pretty sure every carb i've ever seen in my life has the throttles cracked slightly at idle.

                With the carbs properly cleaned, the throttle plates will appear to be almost fully closed across carb throats . The idle/air mixture screw orifices handle the fuel needs when resting on idle stop screw and the transition to higher loads.
