BJ i'm no harley fan i work on them quite a lot and have never been keen on them,but then i ride ducati and lots of people don't like them either.Yamabond would seal up leaky triumphs and norton roadsters it was that good.
I don't think the velocity stack is visible in hobbsys pix but at least it's in focus.Dave they sound tractor like with a saito flex pipe on do they,i thought that would have been to your liking
