Speedo Drive Ratio - Sachs Countershaft

[KJDonovan]

Does anyone know what ratio a VDO speedometer should be set to if I plan on connecting the cable to the countershaft drive unit on a Sachs engine?  I have gone through all the posts here on speedo drive ratios and can't seem to find this nugget of information.

Thanks,
KD
