so i just bought my XB9S from my local dealer for 3k with 17k miles on the ODO. it is all stock except for a D&D exhaust and i wanted to know if i will need a tune for the engine because i am assuming that it's running wayyyyyyy the hell too rich right now. i was putting my rizomas off of my blast on this morning and my dad wanted to hear the engine so he fired it up and revved it quite a bit and it was dumping some black smoke out the exhaust. it also doesnt like to start when its cold unless you gun the gas on cranking and the dealer had to change the plugs because they were fouled. anyone here in illinois that i could get my bike tuned at to make it run better? it has plenty of power, but im guessing my MPGs will suffer quite a bit from lack of proper fuel management.
