I have just returned from a trip to Belgium and while i was away my bike has developed a loud rattly knocking noise in the engine. Its worst when just ticking over, kinda smoothes out once im moving.
Its a 2004 model xtx, its done just over 10k miles n apart from the first free service iv been doing all the work on it myself and i want to continue doing so.
Does anyone have any idea what could be causing the noise and if it can easily be fixed? Its been suggested by a friend with a little more mechanical knowledge than me that it could be that the timing chain is loose and jus needs tensioning. (i dont even know if the bike has a timing chain?)
Thanks AndE
