Stage1 – Remove stickers that could land me in trouble
Officially a 1977 Kawasaki KZ650B, testament to the fact that if enough people change / customise enough parts over a long enough period it becomes impossible to find an original part.
Stage 2 – Dismantle down to component parts.
Steering head pin cracked! – plan B buy replacement ninja 1995 yoke from ebay. The reason for the crack becomes apparent, modified because the original does not fit the steering headstock. Plan C, fit CB750 yokes with taper roller bearing conversion.
