Re: Silence my bike
When I used to fly remote controlled airplanes I experimented with the muffler. The engine was a two stroke with a muffler. I put a piece of silicone tubing (used on the plane for fuel tubing) on the tip of the muffler. The tubing was about 1.5" long. It reduced the noise by more than half. So much so that I couldn't believe it. Maybe try experimenting with tubing on the tip of the muffler.
