General
The oil pump is driven by the clutch drum. Lugs
on the clutch drum transfer the power to the
drive arms of the oil pump drive 1.
The drive worm of the oil pump drive engages
in the teeth of the oil pump 3.
This means that oil is pumped only when the
chain is running.
The oil flow 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.
Turn the oil pump drive 1 counter-clockwise
and pull it off the shaft.
Pull the oil pressure line 2 from the oil pump.
Unscrew screw 4 and remove the oil pump.

stops.
