question,
if the mfgs can put lotsa holes in the back for exhaust, why cant they put lotsa holes in the front for more intake?
i prefer a full face but, behind the windshield on the I/S it gets too hot during the summer.
they can put huge vents on the offroad helmets, why not street helmets?
I'm no engineer, but I'm guessing more exhaust flow can probably increase intake flow via reduced #'s of or smaller openings.
Is I close anyone?
