Suggest the dynamo/alternator needs an overhaul.

Agree with the above, however if you are still running a dynamo, it could be the control box which is low down on the front offside in under the air box intake pipes. :)

could even be as simple as a fanbelt loose. Difficult to hear at higher revs.

If you have an alternator, most likely the brushes have worn. They seem to do about 70k miles before giving trouble.

If a dynamo, then as Charles says, you need to look at the regulator, although it could still be the brushes!

Cheers,
Mike.
