8.3 Spark plug maintenance
Spark plug recommendation: TORCH F6RTC, NGK BP7ES, BOSCH WR3C.
1. Unplug the spark plug cap (B) pulling outward (as shown in the figure below).
2. Using the spark plug spanner (A) to extract the spark plug by unscrewing it from
the engine (turn counter clockwise)
3. Inspect the spark plug visually. Replace with a
new one if the insulator is cracked or chipped.
Clean the electrode with a fine wire brush to clean
the filth deposits.
4. Measure the electrode distance with a gauge.
Normal value 0.6 - 0.8 mm. Adjust the opening
carefully if the value is not correct.
5. Carefully replace the spark plug, begin screwing
with your hand to avoid damaging the threads. Once
the spark plug is threaded to the end of the thread,
make the final tightening:
New spark plugs: 1/2 turn using a spark plug spanner.
Used spark plugs: 1/8 to 1/ 4 turn using a spark plug spanner.
6. Reinstall the spark plug cap.
