Missfire above 8000 RPM - Ignition?

[Nicholas H]

Hey Guys,

I'm not sure if anyone is active but it worth a shot. Im working on a 2006 GS500F.

Did a carb clean and installed a new carb kit. Bike runs smoothly up until 8000 / 9000 RPM where it will start to missfire. It doesn't stumble or anything, its just a momentary missfire. If I keep the throttle open it just keeps missfiring every 2 seconds.

Im thinking ignition? Any direction on what to test first would be appreciated.
