Hurrah Gentlemen!!! Picked up my Baby today ('twas Good Friday)...all seems well with the total warranty crankshaft positioner sensor (which is attatched to the stator as one unit) replaced within a working week.
They finally found the green connector for the diagnostic test and it said a fault in the throttle body unit. The amperage checked out to book specs so the dealer was going to put a new ecu unit to see if it ran right. They thought the "brains" weren't telling the engine when to correctly send the spark.
Having just gotten my C_5 I really hope the bike is more reliable than you would be led to believe reading some of these posts!
