Info about my Honda Dax?

Hi I was given a Honda Dax and wanted to know some information about it like the year, how many liters is the tank etc... the chassis number is located on the side (below the 70) shown on the picture. The chasis number is ST70-562768 and the motor number is ST70E-143245

Hi jimreyes, looks like a well worthwhile project, my ST is a 1972 but yours looks to be a newer one than that but my manual says that the fuel tank capacity is 2.5 littles including the reserve supply
