MAINTENANCE
This should be done approx. once every 1000 km, while the plug must be changed once every 6000 km.
– Refit the spark plug, inserting it first by hand and only using the wrench for the final tightening.
– Replace the spark plug cover tube (1), ensuring that it has been inserted correctly.
Whenever the spark plug is changed, check the pitch and the reach of the thread. If the threaded part is too short, carbon
deposits will build up on the thread seat thereby risking damaging the engine when the correct spark plug is refitted.
Only use spark plugs of the recommended type, see (SPECIFICATIONS), otherwise engine performance and life could be
adversely affected.
SPARK PLUG
The spark plug is a very important part for good engine
efficiency and special care must be given to it.
Before unscrewing the spark plug, the engine head
must be cleaned with a jet of compressed air to prevent
particles of sand, mud or any other type of dirt on it from
entering the cylinder.
Disassembling the spark plug
The engine must be cold for this operation.
– Remove the spark plug cap (1).
– Release the spark plug (2) using the relative wrench and
then unscrewing by hand until it can be fully removed.
– Clean it with a metal brush and check that the distance
between the electrodes is 0.5 - 0.6 mm.
