hi all just looking for advice i washed my bike after its first service and then fitted a set of vance and hines black widow mufflers (just the slip ons) i was assured by the dealer that i wouldnt have to change the computer as i didnt change the full exhaust now when riding around town i hear an air pump like sound from the motor which wasnt there before would this be a trait of the new mufflers or could i have gotten water into something i shouldnt have?
also blows a little bit of black smoke when revved is this normal?
should i take the pipes back off to see the difference in the noise?
any help is greatly appreciated as this is my first harley thanks.
