Drive sproket wobble

I have developed a one off "clunk" noise when first accelerating from 1st gear. Upon inspection of the front drive sproket I have noticed that the sprocket has a bit of a wobble on the drive shaft. The moment is towards and away from the motor.

So the questions. Is this normal; if not it is a matter of retightening (though everything seems locked down), or is it work and needs to be replaced?

The sprocket wobble is normal. The splines are a little bit loose. The clunk is most likely due to the chain being too slack. This can make the whole drive train feel sloppy.

Yes the sprocket is designed to be loose on the countershaft, though I don't know why. Seems like it would wear out the splines a lot quicker. I liked the ones with a large bolt holding them on. They didn't move, but were harder to get off. As said, check the chain adjustment, if that is ok, check the teeth on both sprockets, and see how much adjustment room is left on the chain. If there is almost none, the chain is worn out. If the chain and sprockets check out ok, and the adjustment was correct or you adjusted it, there may be an internal problem. But a "clunk" usually comes from quickly taking up slack in something.
