There is more to intake design than an air filter. Just as pulses bounce thru the exhaust, the intake is pulsed. Having a "volume" between the air filter & the carb is important, On a fat single, having a little more volume than the 652CC displacement smooths that pulse & doesnt make the engine work so hard to get air to run in. Instead of going with a cone filter, I modified the filter box, cutting a divider out & increasing the volume between the filter & carb. No water in the intake in a rain, it ran really good.
