You won't need Witworth on that bike. They used standard SAE stuff on that. Only specialty tools you will need is the timing plunger and degree wheel unless you want to take the engine apart. If that has the later model crankcase and crank shaft to go with that primary cover timing is a piece of cake. The later bikes had 2 holes drilled in the crank, TDC and firing position.
