so after cleaning my air filter for the first time tonight, I notice that the filter and location seem really restrictive. I am just wondering if anyone has done any mods to provide more air into the carb. Seems to me you could almost ditch the hole box and put a simple k&n style filter on it and give the motor a little more air....has anyone done this? or at least noticed the same thing? After taking the side cover off, I wondered how air even got into the carb.. Seems ineffective to me!
