It must be a harley thing, because the guys riding crotch rockets don't do it.
No But they blow by on I680 at WOT at God only know what speed and I have to admit I always listen for an abrupt change to the the sound. I refer to them "STATISTICS". I do have to admit to being both a harley and crotch rocket rider years ago and was guilty of both offenses
Also wanted to mention one of my relatives was a friend of an idiot that was chased from Iowa to his house in Omaha at speeds exceeding 185 MPH on a Suzuki Hyabusa
