I don't ask many techy questions, so if this one has been asked before sorry. I have recently added V & H Big Shots to my 04 1300R. Is the jet kit necessary for my bike? It sounds good and does not back fire. Opinions needed!
Most of the post I have seen say No, not unless you change the air intake.
With that in mind, since your bike has Vand H pipes on, For better performance to take advantage of your pipes you may concider adding an air kit, then yes you will need to rejet, Its not that difficult and there is some great info check out http://www.vtx1300tips.com/
