This means that oil is pumped only when the
chain is running.
The oil  ow rate can be adjusted with
adjusting screw A:
•• Turn right for more oil
•• Turn left for less oil

Disassembly

Remove the clutch drum and clutch, see
chapter 04. Remove brake band, see chapter
03.
Turn the oil pump drive 1 counter-clockwise
and pull it off the shaft.
