Electronic control unit (ECU)

1
Remove saddle and fuel tank (see Section E) to gain access to the electronic
control unit (1).
It is composed of a capacitor, a rectifier circuit that handles input signals received
from the pick-up sensor, a circuit that controls ignition timing advance in accord-
ance with pick-up sensor inputs and a switching circuit for capacitor discharge.

Spark plug
A= 0,8÷0,9 mm
0,031 ÷ 0,035 in
The spark plug (1) is an "NGK" CR9EI spark plug. Check electrode gap "A". A
wider gap may cause difficulties in starting the engine and overload the coil.
A gap that is too narrow may cause difficulties when accelerating, when idling
or poor performance at low speed. Clean off any dirt around spark plug base
before removing the spark plug. It is good practice to closely inspect the spark
plug after removal, as any deposits on it and the colour of the insulator provide
useful indications on spark plug heat rating, carburetion, ignition and the general
condition of the engine. Before refitting the spark plug, accurately clean the insu-
lator with a wire brush. Smear some graphite grease on spark plug thread, do it
fully home finger tight then tighten it to 10÷12 Nm torque. Loosen the spark plug
then tighten it again to 10÷12 Nm. Spark plugs which have cracked insulators
or corroded electrodes should be replaced.
