I have a c70 minnus an engine so aquired a c90 engine which I believe to be off a model around same age (round headlamp model with bullet connectors)and engine mounts don't line up. I can see I will have to redrill the mounts but if anyone has done this before would be grateful for some advice please. Also the bike is yellow, does anybody know the paint code or a similar colour I could use to repaint it?
