I'm new to this forum and not sure if I'm doing this right. I have a used 2005 650 Burgman. I hear a noise sometimes (like a rattle or something is loose ) on the right side about where you foot would rest. the scoot has 20,000 miles and runs good. Someone told me I have an exhaust leak and might need new header gaskets. Has anyone else ever experienced this problem or shed some light on what the noise might be.
