If its anything like mine when i picked it up it came set up richer than Donald Trump ..smoked like a steam ship ..that was quickly corrected ..You will love this bike for its agility and low speed trackabilty best of both worlds, it has made me very fast in the tight woods ..there is so much tweeking you can do to these bikes to squeeze every last ounce of power from them ..my poor 390 and 550 have taken a back seat to this bike i cant get enough of it. The very first thing i had to get used to over a 4 stroke is lack of engine breaking lol
