Yeah, really a bummer. I was hopin to hit mo one last time this year. I'm stayin hopeful & will be checkin the radar tomorrow. I do have some brand new rain tires I could try out though..
I just installed a hotbodies mgp growler slip-on onto my street bike (2007 gsxr 600). Its really loud & sounds similar to your example. Some of the guys I ride with say its too loud but the cops never mess with me. Check out hotbodiesracing.com; not sure if they make em for every bike.
