So I have an issue that when my bike is coming down in RPM it drops below the idle limit and the bike stalls. I've asked my mechanic and my dyno tuner guy and we're all pretty unsure. I have a BMC race air filter, Akrapovic mid pipe and slip on, and the ECU is flashed and tuned. The issue has been happening since before the ecu flash and tune so that isn't the problem. I don't remember exactly when it started though. Any suggestions?
