Part number Description Use
Part no. 897651 LOCTITE 243 Screw locking

rect positioning of this valve leads to disturbed running
of the engine due to incomplete combustion.
The reed petal is bent, not flat. It must be fixed with the
concave facing the valve guide. If the valve guide with
the correctly fitted reed valve is held up to the light, it
must not be possible to see through it.

cessed head screws (3). Use LOCTITE 243 to lock the screws.
2 Position the gasket (4) on the cylinder (5).

screws (8). Tightening torque 6 Nm (55 in.lb).
