I watch with interest, Had a click.... could be described as a clonk for a while now when i pull off. and every now and then a clicking at very low speed to or rolling the bike freehand.
I have tried time and time again to MAKE it happen and fail every time lol. i have checked sporockets, chain, alingment, slack, bearings wheel and swing. shock mounts, shock and everything inbetween.
Chain has about 14k on it now maybe a little more and is lubbed by a scotoiler
deff sounds chain related but just cant find it or make it happen at will
