I asked this on my other post, but thought I should make it it's own thread. I am breaking in my 06 10r and trying hard as hell to keep the rpm's under 4k for the first 500 miles. Anyway at ~3k to 3.5k rpms the bike keeps making this "fluttering" vibration. I can't tell where it is coming from and it seems to go away as I reach ~4k rpm. This never happened when I broke in my 6r. Of course this is my first liter bike and I'm maybe just being paranoid, but that noise doesn't sound right. Does anyone else have this happen with theirs? It would make me feel better. If not any ideas on what it might be?
