Hi there I have an '06 r6 with a 520 chain/sprocket convertion......and i have a problem. I am hoping that one of you guys might be of some help from your experiences...I have had that chain/sprocket on there for maybe half of a year and the damn chain keeps loosening itself....VERY loose to the point where it just slips around the sprocket and i cant ride it. At first i would loosen the back wheel and tighten the chain up, but i realized it just gets loose again the next day, and the back wheel has not moved at all!........can anyone help?? do chains wear out or something?? ..thanks!
