Hello / Bonjour For some time, I heard a strange noise on my beauty (see: ). According to my research, this could come from the chain tensioner ... has anyone ever had this? For information, my bike has 40 000km so the mechanical review (revision in English ?) is to be done (and so, valve play + synchro... which will be able to solve the problem?). Otherwise, it works well, no particular problems. What do you think ? Thanks !
