I am not sure if anyone else has ever had this problem, but I am getting (what sounds like) detonation/pinging on light-to-mid throttle in the lower RPMs once the bike gets warmed up. I have a PCIII using Booth's map, full race Hindle exhaust, and the flapper is removed. I have tried 4-5 different types of high-octane (92-93) gas with no luck. When I get into the upper RPMs, I can not pick up any audible detonation. Does anyone have ANY idea of what might be the problem here? The bike rides and performes fine...but the last thing I need is a blown engine.
