Spark plug maintenance

3. Use thesupplied spark plug wrench to unscrew thespark plug.
4. Clean theelectrodes and check that theelectrode gap is 0.028–0.031 inch (0.7–0.8 mm). Suitable gap
measuring tools are sold separately. Screw thespark plug back into place and reconnect thespark plug cap.
Fuel filter
The fuel tank has afilter fitted to its filler hole. Regular checks should be made to ensure that thefilter is clean
and in good condition. The filter prevents impurities from entering thefuel tank and thefuel system. Always
clean thearea around thefuel filler cap before removing it and make sure that thefuel you use is clean and
contaminant-free.
