So now i got an FMF pipe, and if i get the UNI, will i have to jet the carb or not???
Whats the sizes on a stock 400ex jetting???
What sizes wouls you suggest after the FMF and an UNI???
What if i get the precharger for the filter??? or would that defeat the purpose of the filter??? I would buy an UNI but i kinda like K&N better.
