The sprocket is located undemeath the clutch drum
(W2).

Wom out sprockets (C) may damage the new chain and must
therefore be replaced. If the wear marks on the teeth are very
pronounced (about
0,5

Replacing the suction head
The spark arrester screen should be checked and cleaned
regularly.
The felt filter ( O n ) of the suction head can become clogged. It is
recommended to replace the suction head once every three
months in order to ensure unimpeded fuel flow
to
the carburetor.
To remove the suction head for replacement, pull it out through
the tank filler neck using a piece of wire bent at one end to
form a hook.
