Single cylinder thumpers through open as possible pipes are where it's at for me.
My Enfield Bullet 500 with rejetted carb and debaffled reverse cone silencer was brutal.
Much as I quite like the sound of many bikes, (I have had Laverdas, Guzzis, Triumphs Ducatis and Buells, many with "modified" exhausts), it isn't very sociable, and it is a bit like RLJing. It needlessly pisses people off. I would rather get around a bit more discretely. I fixed my silencer by making a baffle from a biscuit tin, which was amazingly effective. It has knocked some power off, but with 150 horsepower I can afford to lose some!
