STRIPPING DOWN THE

REED VALVE

- Withdraw the carburettor from the

engine

- Remove the inlet nozzle securing

screws, as is, and then it is possible

to gain access and withdraw the

reed valve.

- Check that there are no signs of

cracking, deformation or breaking in

the valve reed petals. If signs of

damage are present, replace them.

- Remove the opening limiter plate

and inlet valve reed petal securing

screws and check that there are no

cracks in the securing base of the

petals. If cracks are found, replace

the valve reeds.

ASSEMBLING THE VALVE

REEDS

- Assemble in reverse order to strip-

ping down, paying particular atten-

tion to the correct positioning of the

opening limiter plate and the reeds

(it is necessary to mate the beve-

lling). Elimination of the opening

height limiter will change the perfor-

mance of the engine and may affect

engine reliability.

- Check the reed valve box O-ring

and replace if it shows signs of

damage. Install a new gasket.
