- Highest quality inlet or exhaust valve manufactured by G & S Valves - to fit Norton SV (Side Valve) 16H 500cd engines. Price is per valve
This valve is the standard specifcation Norton valve fitted to side valve (SV) 500cc single cylinder Norton models from the early 1930's to the late 1950's. I am not entirely sure if this valve will also fit pre-1930 Side Valve Norton engines- but email us at sales@racingvincent.co.uk if you need more detail on dimensions.
Please note - this valve does not fit the similar side valve Big4/Model 1 596cc engine (which has a slightly different length stem). Email us on paul.norman@racingvincent.co.uk if you have this model - I may be commisioning some of those valves in the future
Final point on valves - Norton single cylinder SV valves are not interchangeable with SOHC or OHV valves - however, the collets for side valve engines are the same as the OHV valves and we do sell these collets - Item Number: 0675.
Note Feb 2024: If you have a 1920's sidevalve Norton - of the type that has a slot to retain the valve springs at the end of the shaft - and are looking for replacement valves, or if you have a 1930's Big4 sidevalve - you can contact me on paul.norman@racingvincent.co.uk as if I have enough interest I will look at having batch's of both made
