the bike is new to me. I bought it about a week a ago for my wife. It is in good condition but I fully expected to have some repairs for the price that i paid ($1400). The noise actually is not constant, just when i rev the rpms up, for a second or two, just sound slike a rattle. My bike is a 2003 with mods and it seems much tighter and runs very smooth (i guess because it is so much newer)? thanks for any help/ideas
