:? Hey Everyone, Hope everyone is doing well. I have a question regarding tune up on my 1600 Vulcan. Its snowing here in NJ so i figured i would keep busy and do an oil change and check my plugs and filter. When i pulled the plugs they were black and i noticed the last few times starting it that black smoke billows out of the top pipe. I have cobra pipes that were on it when i bought it, and as far as i can see there is no programmer on it. The smoke does stop as it warms up, but i notice that when holding the throttle at a steadiny rpm it breaks up a bit. I am thinking thats its running to rich, which a programmer would fix. Any Help and advice would be appreciated. Thanks John
