Hi all,
I am rebuilding TR77 250 OSSA with a Reed valve conversation. When the engine was stripped down the following was found (Keith Horsman, Reed Valve Developments, Silsden, Nr. Keighley.) I have tried to trace Keith Horsman but no luck and the number is out of service. Has any one come across him and OSSA Reed valve Developments? It would be good to know any information in particular the original reed valve information. Attached is picture of the details on Keith. Any information would be of help.
