    Need help with jetting

    I just ordered a K&N Jet-kit and I am wondering how, and what jets to put in. I have a Yoshimura Slip-on and a K&N airfilter also I have a Splitfire sparkplug if that makes a difference. I have no holes in the airbox and dont plan on doing it. What jet do you recommend for this?
