Mine had a gimp engine from the get go... I figure i was one of the rare few... It took the dealer over 60 days to diagnose and replace the engine... which had to be hand built just as it was at the factory... The mechs at the dealer built the engine from scratch and it runs like it should now with no other problems to speak of. The only thing that bothered me the most about this whole deal was the amount of time it took the dealer to obtain parts... in most cases it took over 15 days to obtain even the smallest of parts from way out of state parts warehouse. (only one in the USA) SO... moral of the story... if it needs a part... its gonna be a while... but as you see here, most people haven't needed a part.
