I just asked my brother about this and he told me that the benefits of changing the jetting vary by elevation. For example, I wouldn't see the same sorts of increases in power in Tucson, AZ (elevation 2643') as jetblackchemist in Columbia, SC (elevation 295') because more air than fuel is needed in my mixture to compensate for the lower concentration of oxygen in the air.
I am interested in knowing what kind of air filter you run. Is there a K&N that fits properly? Do you just use a UniFilter? Do you know any part numbers?
