Do you guys think running with side covers off, mainly just on the side of the intake, has any significant effect to performance by allowing more air to contact the air filter? Also, what about intakes that angle out?
Personally, it seems to me that a side cover over the air cleaner wouldn't serve as a restriction because there's more then adequate space for air to sneak in, and the bike will only take as much as the carb can suck in anyway..
what do you guys think? I see a lot of kitted bikes with no side covers/intakes angled outward. No covers just for show, or does it actually serve a functional purpose?
