Norton Rocker Box Breather in Aluminium - Twins
Designed to fit twin cylinder Nortons including the Dominator, Atlas and Commando, this inspection cover allows fitting of a breather. A breather in the rocker box will help to reduce oil leaks from the top end of the engine, as well as reduced oil being forced down past the valve guides to be burnt.
Manufactured in LM25 aluminium. The set comes complete with a banjo and bolt to accept a piece of 8mm (5/16'') pipe (not supplied).
