Thanks for the tip...it's not any louder than any of the Harley's running around. Besides I live in such a rural area the only ones that would think I'm a jerk is the cows. I'm more interested in a performance gain on the top end. It tops out at 138 with full Termi exhaust. I ride with a fast group of Jap bikes & they pull away around 130. Just a bit more power would do. Any other ideas on how to squeeze more out of it? Gearing maybe?
