the rattle is gone, it would appear to have been the thrust bearing fork being badly adjusted and this has been cured by a capri clutch cable with built in adaptor.
the oil i used is a bit thicker than the standard spec and this has resulted in a clunky change when cold.
unfortunatley the test drive was limited to 5 miles as there is now an over heating problem. a leak some where, but it is too dark to see now.
many thanks for all the advice lads
