Does any one knows where to by a blank rear sprocket for my MK IV the only thing I know is that it should be 60T the size I don't know (I only have the drum)

Hello Mikael,
                   Being a British bike, the Mark IV Douglas uses an imperial size chain ½" pitch x 5/16" wide. Here in the UK, 60 tooth sprockets are available from bearing stockists - they call them 'plate wheels'. As supplied, they only have a pilot hole in the centre - you would have to get the centre bored out to suit your brake drum.

  Regards,
                Eddie.
