When I put my bike on the centre stand, put it in neutral and roll the wheel forward with my handat a constant speed, the chain seems to slacken, and then pull tight, and then slacken and so on...almost as if the front sprocket would have been a oval shape, but obviously that's not the case. What can be the cause of this? Am I due for chain and sprocket replacement? Its got about 15000km's on it, but still looks in good shape.
