Ignition Timing; Cooling System - GAS GAS EC 125 - 2003 Service Manual

IGNITION TIMING

Because a capacitor discharge ignition (CDI) system is used on this
motorcycle, the ignition timing should never require adjustment
unless the magneto stator is incorrectly installed during engine
reassembly. However, if there is any doubt as to the timing, inspect
and adjust, if necessary, as follows:
Ignition Timing Adjustment
- Remove the magneto cover (A).
- Check to see if the center mark of the three marks on the magneto
stator (C) is aligned with the mark on the crankcase (B).
(A)
125 cc.
200/250/300 cc.
(B)(C)
EC 2003 -
- If the marks are not aligned, loosen the magneto stator screws
and turn the magneto stator.
- Tighten the screws securely.
- Install the magneto cover.
The ignition timing can be adjusted for different power and to
suit the rider´s preference and ability.
- Remove the magneto cover.
- Loosen the stator screws.
- Adjust the timing by shifting the stator position within the three
lines.
For the best engine performance, it is very important to adjust
the ignition timing within the adjustable range just explained.
- Tighten the stator screws securely.
- Install the magneto cover.
- Test ride the motorcycle and readjust the ignition timing if necessary.
