Hello, more informations on the ZENITH in restauration. I've the engine and clutch at the workshop. Its a twin, 8HP, and the stamp readable is: 66689, following by '8HP' and '830cc'. The bike is, I think, a 1914 model. I look fot some information. Mainly, the valves lifter in missing. A picture of them is a good helping. And also some details, but I work on the engine in first. Thanks for all. Daniel.
