Sorry I didn’t explain why the coil is where I’d start . Had my sons banshee runs great until high rpm sputters missing poping like bad jetting. After half a day of tinkering. Swap good coil from other banshee runs great. The coil was breaking down under high rpm and load. It’s just 2 10mm bolts and a plug. I have a 10 mil serval and I’m running all OEM ignition.
Have a Merry Christmas
