- Visually inspect the old coolant. If whitish spots are observed in the liquid
is a clear indication that the aluminum parts in the cooling system are cor-
roded. If the coolant is brown, iron or steel parts of the system are rusting.
In both cases, flush the cooling system.
- Check the cooling system for damage, leaks or missing gaskets in the co-
oling system.
- Install the water pump cover drain screw with the specified torque values
shown in the table. Always replace the gasket with a new one.
Drain plug tightening torque
Water pump screw: 9 Nm
- Fill the radiator up to the edge of the cap with coolant, and install the
radiator cap.
- Inspoect the cooling system for leaks.
- Start and warm up the engine, then stop the engine.
- Check the coolant level after the engine cools down. Add coolant up to the cap.
SPARK
The standard spark plug is a shown in the table and should be tightened to
13Nm.
Standard Spark Plug
Standard spark plug Gap between electrodes: 0,7 - 0,8 mm.
The spark plug should be removed periodically to check its gap. If the plug
is oily or has carbon deposits, clean it with a sandblaster. After removing the
abrasive particles, the spark plug must be cleaned using a wire brush or a
similar tool. Measure the gap with a feeler gauge, if incorrect adjust the gap
by bending the side electrode. If the spark plug electrodes are corroded or
damaged, or if insulator is cracked, replace the plug.
NOTE
Inspect every 30 hours and change every 60 hours.
To find out whether the right heat range plug is being used, remove it and in-
spect the ceramic insulator around the center electrode. If the ceramic is light
brown, the spark plug is correctly matched to engine temperature. If the cera-
mic is whie, the spark plug should be replaced with the next colder plug. If the
ceramic is black, the spark plug should be replaced with the next hotter plug.
NOTA
If the engine performance drops, replace the spark plug first to recover
its output.
Spark plug maintenance
- If the standard spark plug is wet then replace it.
- If the standard spark plug looks glassy or has a white colour, replace it
WARNING
An incorrectly fitted spark plug, or an incorrect temperature can lead to se-
vere damage to the engine, and this damage is not covered by the warranty.
Always use the manufacturer’s recommended brand of spark plug. Check
with your dealer or a qualified mechanic to determine the correct spark
plug for your motorbike.
To remove the spark plug, follow these steps:
