questions like this make me wanna start selling k&n pods along with the other bits, along with my kit.
Anyway, aside from rejetting and whatnot. You'd need a carb brace and a crankcase breather filter. The carb brace can be a fancy expensive piece of metal or a simple turnbuckle from home depot depending on what you wanna spend. The breather filter and fancy carb brace can be bought from newspeedmaster.com I'm not sure of the size though because my bike already had one when I bought it. Maybe someone will chime in.
Send me a private message me when/if youre ready to buy a bracket. I can answer any questions you have as well, its not a problem.
