It all started with a need for some storage on my Deluxe. Decided to go with RK hardbags, love the look and the size of the bags. Now I need to change exhaust to allow for the bags. Think I am pretty well decided on the V & H true duals but I got a question that I can't seem to get a straight answer on. Do I have to change the air cleaner? Hearing the Arlen Ness Big Sucker is the way to go if I do. AND...do I then need to purchase the Screaming Eagle super tuner? Fact is I will never need or use the full torque or horsepower of this bike as it is so increasing them is not a necessity for me. However, I do want my bike to run correctly and do not want to suffer any damage due to not tuning when it is necessary. I can't wait to get this bike ready cuz it's time to start putting the miles on, any help is soooooo appreciated!
