A lot of today's factory dirt & dualsport bikes are lean & restricted on the intake end. Like I ran my DRZ with the 3x3 airbox mod, jet kit, but stock pipes. If the intake is restricted and the carb is lean to begin with, that limits what can be accomplished with the exhaust.
What do 250S riders do with the intake end of things?
