2002 Kawasaki Vulcan 800. When I start the engine, I hear a slight rattle that sounds like it's coming from the front exhaust when it connects to the head. When I rev the engine and release it, I can hear the rattle pretty loud. The previous owner took the baffles out of the exhaust prior to me owning it. But just started hearing the rattle yesterday. I ride it daily and new to riding. I'm just trying to see if someone else has this problem or any resolutions? Bad weld? Baffle pieces? Exhaust leak?
