Hi Mr. Data, not long back from Italy, and just getting back into the swing of things, next up was going to be an exhaust upgrade however, the 2007 engine looks as if it is a scary beast to modify. The nightrider site looks great, but I'm no spannerman so still need to seek good advice. I'd like to get a better rumble from the exhaust but not too loud along with a good look and some extra power. This throws up the nightrider comments regarding fitting stronger crankshaft bearings. Would appreciate your thoughts as you ride the same model as me. Cheers, Powerset.
