Anyone Running this set up ? if so what jetting changes did you make from the HRC Spec's ?

im pretty sure u dont have to change the jetting. the K&N dosent flow any more air than the stock so the jetting dosent need to be changed. thats what my dealer told me. mine runs fine without changing the jetting.
