Hey Guys, did some searching and didnt find anything about this. But it seems like when i'm riding the real rough stuff, like an old dry river bed or somthing my 650r motor sounds like its going to come apart any second. I can really hear it when i'm standing and leaning forward over the bars. I've noticed it in my 600r also, but I was wondering if this was normal and if so, if someone could explaing why. Thanks.
