Spark Plugs Removal and Installation
Removal
1) Remove air cleaner assembly with air intake pipe and cylin-
der head upper cover.
2) Pull out high-tension cords by gripping their caps and then
remove ignition coil assemblies referring to “Ignition Coil
Assembly (Including Ignitor) Removal and Installation” in this
section.
3) Remove spark plugs.
CAUTION:
• Never attempt to use metal conductor high-tension
cords as replacing parts.
• Insert each cap portion fully when installing high-ten-
sion cords.
CAUTION:
• When servicing the iridium/platinum spark plugs (slen-
der center electrode type plugs), do not touch the cen-
ter electrode to avoid damage to it. The electrode is not
strong enough against mechanical force as it is slen-
der and its material is not mechanically tough
• Do not clean or adjust gap for the iridium/platinum
spark plugs.
