A Kingpin Components Vernier Sprocket designed to fit all single cylinder Nortons with 16T magneto sprockets.

 

Norton used 15T sprockets on their singles until the engine underwent a major re-design in 1948. If your engine is pre 1948 then you will probably need the 15T version which we also sell. However as so many of these engines have been worked on over the years, we recommend you check what you currently have before ordering. 

 

The usual method of setting ignition timing is by removing the standard sprocket from the magneto taper and replacing it in a different position. This method makes it very difficult to make slight adjustments in timing and virtually impossible to return to a previous setting as you are essentially starting again every time. 

 

Using a Kingpin Components vernier sprocket for setting your ignition timing makes getting your timing spot on considerably easier and far less time consuming. The use of this vernier sprocket allows fine adjustment in increments of just 2.35° rotation of the crankshaft. The vernier sprocket has a major advantage when searching for that last ounce of performance. When experimenting to find optimum ignition timing, if testing shows that you have gone too far in one direction, it is always possible to quickly return to a previously known setting. 

 

Included with every kit is a comprehensive instruction sheet.
