2. After cleaning the cover (2), remove the used air cleaner
primary (4) and secondary (3) element.

element.
(When reassembling)
• Install the air cleaner cover with "TOP" indicated on the rear of
the cup.
IMPORTANT
• Make sure the hooking clip for cover for the element is tight
enough. If it is loose, dust and dirt may be sucked in,
wearing down the cylinder liner and piston ring earlier and
thereby resulting in poor power output
