i plan on putting a pipe on my bike. i already have a k&n filter inside the stock air box. that will be the only mod. trinity says165 left, 170 right. pilots stays stock and the needle stays stock. can i just buy these jets from my dealership and go by trinity specs.
question is that hmf pipes call for a different jetting size and i don't know about the needles, this is crazy. what have you guys recomend from your experience. i ride in missouri
also do you recomend a full pipe set up or would i be happy with just a slip on and have the same results.
