RE: Are BME engines any good ?
IN answer to these questions. . .
YES, never a broken crank, great power, super light weight, the cutting edge of engine design at this time.
Vibration? Heh, learn how to tune a carburetor. They all shake if they are out of tune, and all my BME's run very smoothly at idle.
Add 500-600 rpm for the same prop.
NO!!! Call Keith for a definitive answer on this one.
