I just got home from having a new Avon Venom put on the back of my Heritage. Since I haven't had it very long I haven't had the opportunity to hear it run with someone else riding it, a very rare occurrence since I don't let anyone ride my bikes except at the shop I take it to for things I don't want to do myself. Both my Sporty sounded and now my Heritage sounds even more different when I'm riding on them than other guys bikes. The Heritage exhaust note especially just sounds funny. But when the shop mechanic started her up and headed around the parking lot with her I let out a huge AAAAAAAAAAAAAHHHHHHHHHHHHHHH!!!!!!!!!!! When I'm away from her a few feet she sounds GREAT! Now I just have to keep the idea in my head that the sound is different sitting on the bike than hearing her go down the road.
