Like I mentioned in a previous response, I like the sound, I was just making sure it was normal...What am I missing? Suzukis are famous for intake howl (almost all Gixxers). When the Busa hits it's stride it sounds like a wolf is chasing you. Are you guys saying that's not normal? When I got my Busa dynoed at a Ducati dealer you could hear the bike running then it rolled up into the power and everyone's eyes went wide as baseballs and they said what the F' is that? I smiled and said "That Sir is a wolf howling in the land of bikes that clatter". Lol, I still like that one!
