Norton Rocker Box Breather in Nylon
Designed to fit push rod Nortons made from 1948 up until the introduction of the alloy heads, 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 and the push rod tubes, as well as reduced oil being forced down past the valve guides to be burnt.
Manufactured in nylon, these covers have a great finish and fit. The set comes complete with a banjo and bolt to accept a piece of 8mm (5/16'') pipe (not supplied).
