hi there, i am new to this forum so i apologise for any misconduct if any.
i took my bike for a drive last night and it was running beautifully, i then started it up for work this morning and it now sounds like a dirt bike??!! it sounds like something has come un attatched but i couldnt see anything unusual near the exhaust pipe. everything seemed to be all in one piece, i gave it a wobble and it seemed a little loose but not hanging off.

just so you guys know, im not a mechanic and i have no idea about mechanical engineering so lamens terms would be helpful!

if you have any ideas as to whats happened to my poor bike please give me all the info you can, i.e, is it dangerous to ride while in this condition?

cheers.
