Hey rich! Glad you found it. To answer your question about jetting the carbs, it most likely WILL have to be done. Jetting the carbs simply involves removing the tank, removing the carbs, removing the carb bowl (Under-side of carb) and exposing/replacing the jets.
As far as what SIZE you need, someone else will have to help with that. BUT After doing all of this, you will have a little more HP and a sweet-look!!
