There was virtually nothing left of the teeth on my rear sprocket, since being replaced there's no more screaching and a lot less 'dust' under the rear cover .
Going back to headlights...one of mine keeps working loose, have used loads of loctite on the nut but it still rotates below the bowl, any suggestions ? Also 3 of the rivetts under the headlamp bowls had dropped out! 2 on one side and one one the other.
