HI, Just recently (last month or so) since I have had my stock (CAT) exhaust on my 03 rs the bike has started to make this rattling sound (sounds like its coming from top of the engine area).
What could this be?? I also get it when I accelerate hard sometimes, but its very noticable while slowing down (engine breaking)
Could it be a bearing on its way out or somthing??
Not too sure,
