Ya, maybe I'll get the K&N airfilter then...when it comes time to replace the original. Do you think the K&N really has an effect on performance? I know they claim a boost in hp and yada yada. But is it really true? I do like that the filter is re-useable. That alone makes it worth it. I don't get why the breather needs a re-route in the first place. If it's better for the bike to re-route it, why wasn't it routed that way in the first place? EB dreams up oil in the swing arm, fuel in the frame, funky brake...but it takes yahoos like us (and I mean that in the kindest way) to engineer a better breather? haha. You know what I mean?
