Crm 250 missing parts

[Niggsey]

HI all just joined and am looking for some help I have a mk1 that needs some tlc it's missing the power valve servo and I think the power valve controler am I right in thinking that the mk1 had a separate controler not in the cdi as the later ones had the cdi is there and the bike runs but has been botched up any help would be appreciated on finding a controler thanks Niggsey
