It´s hard to believe how much difference air flow makes. Replace your factory cleaner with a K&N. I removed the air box tube with much happiness. Oh the power! I replaced my fac bars with a black crome unit, I modified the gooseneck cover for continued use. - (but didn´t retain the bar pads) I also dampened the bars with 4 inches of something solid internally. I added a very slick/sporty plexisheild, stellito I think? Easy cruzin @ 100 rain or shine!
