So I searched a bit and didnt really find an answer to my question.
According to the sticker on my swingarm, it is time to replace my chain, as next time I tighten it I will have entered the worn out area on the diagram.
My question is, are these diagrams the bible? My sprockets look medium worn, but nothing crazy. I am down one in the front on an 01 F4i...not sure when the chain was last replaced. Should I just suck it up and replace the set up, as at most I figure I have another 2000kms left anyways.
