- Highest quality inlet or exhaust valve manufactured by G & S Valves - to fit Norton SV (Side Valve) 16H, Big4 and Model 1 engines. Price is per valve
This valve is the standard specifcation Norton valve fitted to side valve (SV) 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 firstname.lastname@example.org if you need more detail on dimensions.
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 August 2018: I will shortly be offering a selection of Norton of other Norton SV valve gear and other engine parts. email on normal email@example.com for more information
