As the title says, what is up with that. Do any of you guys do this? I live on a very popular motorcycle route here in NE TN and my house is near a busy intersection for riders when it gets warm. Every one or multiple motorcycles come to the intersection they all start revving their engines like you would an old carb bike that is out of tune and trying to keep it from dying. Of course 99% of these are HD's. I've had modified pipes on every truck and motorcycle I have owned and have never had the desire to rev up my truck/bike at every stop.
