It seems loads of our 'Mercan GS riding cousins' are having the same problems with their noisy twin cam GS's.
I think it sounds great for a BM but it took a wee while to get used to that GS growl under heavy acceleration....I love the popping and banging when you shut the throttle though and it always reminds me of a Spitfire landing.
Funny how my old HP2E sounded like an asthmatic mouse's fart by comparison
FP.
