Standard Spark Plug
125 cc 0.7-0.8 mm
200 / 250 / 300 cc 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 inspect the ceramic insulator around the center electrode. If
the ceramic is light brown, the spark plug is correctly matched to
engine temperature. If the ceramic 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.
NOTE
If the engine performance drops, replace the spark plug first to
recover its output.
TRANSMISSION
For the transmission and clutch to function properly, maintain the
transmission oil level at the optimum level and change it periodically.
A motorcycle with insufficient transmission oil, deteriorated or
contaminated can accelerate wear and tear and cause transmission
damages.
WARNING
If coolant gets on the tires will make them very slippery and can
cause an accident.
- 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 corroded. 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 cooling 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 (refer to torque table)
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 PLUG
The standard spark plug is a shown in the table and should be
tightened to 27 Nm.
