Wow :!: What are you doing to that poor bike? lol You didnt have one of those crappy flywheel/clutches did you? I like the price of that filter you have, but I think the K&N looks way cool & thats what I'm after. I was going to get a Hayabusa before I picked up my RM. The bike has good enough power, but I like it for the style & handmade exclusivity.
