Just finished the install of a VMod system(Vmod Pipes, PCV & K&N) on my 09 Muscle. Install was easy & the bike sounds great but seems like it is running rich, puffs of black smoke when you start it & black residue on the exhaust tips? This is my first computer controlled bike so I am not sure how I should attempt an adjustment. The only other mod is i am running it topless. Can I do any damage riding it this way till I figure it out?
