KYMCO Super 8 50 4T (2008-2014) Service Specs: Part Numbers and Intervals
Battery, spark plug, oil, filters, belt and torque for the KYMCO Super 8 50 4T (2008-2014): KYMCO service data with the genuine part number and diagram
This is the service sheet for the KYMCO Super 8 50 4T (2008-2014) (single-cylinder 4-stroke, air cooled, carburetted). It lists the battery, spark plug, filters, belt and the rest, each figure with the genuine KYMCO part number for the model years in our catalog (2008) and the diagram the part is drawn on. The figures are KYMCO service data from the KYMCO Super 8 50 4T / 125 / 150 service manual (2008-2014). This sheet covers the 2008 to 2014 Super 8. The 2015 and later Super 8 has its own sheet with different tires and battery. When this page and your own manual disagree, the manual wins.

Torque for the parts you replace
Clean, dry threads unless the row says otherwise. Aluminium cases strip long before a steel bolt complains, so use a torque wrench on the drain bolt and the plug.
