I realize that I am jumping in the middle of this conversation, but would you mind explaining the Stage 1 thing to me? I think it just means that exhaust and air filter have been changed out for better breathing. But on the new bikes, does some computer have to be updated too?
I have a 2010 Ultra Limited that I put V&H slip-ons on, but have factory air filter.
Do I want to just buy a K&N air filter, or buy a Harley Stage 1 kit of some sort?
Sorry for the ingnorance, but this has confused me for years. Thanks!
