I’m fairly certain the crankshaft has a slight bend in it and is robbing it up to 1000 RPM at full throttle. It could also be the front bearing is shot. Fuel is a 30% helicopter blend, 23% low viscosity synthetic oil. I’ll be testing the crankshaft on a feeler gauge and sending it into Louisiana for repair as necessary. Top speed was 8670 RPM, should have easily exceeded 9000 RPM.

Engine mount consists of African black wood and an IKEA table, along with two large C clamps (these are the only clamps that can withstand the significant vibration at full power).
