I have an 87 banshee that starts and runs good until wot then it bogs and backfires. I have cleaned the carbs and rejeted the mains fro 210, 230, 250, 270. It runs the same with any jet. It is just set up with fmf pipes and a uni filter and 32:1 mix. I have tested the stator and the readings are right in the middle of where they should be. Could the stator still be bad? Any help would be great.
Thanks,
Greg
