Cleaning and inspection
Carefully check that:
there are no leaks from the fuel tank
there are no leaks from the tank filler cap
the fuel hose is undamaged and free from wear
the fuel filter is not clogged
the tank vent is not blocked or leaking
the vibration damping springs and stops are not
damaged
Replacing the fuel hose
1
Before replacing the fuel hose, measure the length
of hose between the crankcase and carburettor
and between the tank and crankcase. The correct
hose length between the tank and crankcase is 43
mm (1.69 inches). The correct hose length be-
tween the crankcase and carburettor is 53 mm
(2.09 inches).
2
Remove the fuel hose from the fuel tank using tool
502 50 83-01. Trim off 5 mm (0.20 inches) from the
mitred end of the hose. Fit the fuel filter and
reinsert the hose in the tank.
NOTE!
Do not use knurled pliers to disconnect or
reconnect the fuel hose. This could
damage the hose.
Replacing the fuel filter

First remove the old fuel filter from the tank unit
using special tool 502 50 83-01.
2
Pull the fuel hose out of the tank and pull off the
filter.

Fit the new fuel filter and feed the fuel hose back
into position.
NOTE!
Do not use knurled pliers to disconnect or
reconnect the fuel hose. This could
damage the hose and lead to leakage or
fracture.
