It is a new problem, but conditions were different also… The race was in the wet… It had just stopped raining 5 minutes before. I did turn my air box around to help prevent direct water ingestion into the carb.
It wasn’t on every corner, but almost every corner….. The longer the decelleration zone, the more likely this would happen. I it was a short/quick brake zone, then back on the gas, it wouldn’t happen
