Spark Plug; Transmission - GAS GAS EC 125 - 2003 Service Manual

WARNING
Coolant on tires will make them slippery and can cause an accident
and injury.
- Visually inspect the old coolant. If whitish cotton-like wafts are
observed, aluminum parts in the cooling system are corroded. If the
coolant is brown, iron or steel parts are rusting. In either case, flush
the cooling system.
- Check the cooling system for damage, loose joints, or leaks.
- Install the water pump cover drain plug and cylinder drain plug with
the specified torques shown in the table. Always replace the gasket
with a new one, if it damaged.

Water Pump Cover Plug: 9 Nm.
- Fill the radiator up to the bottom of the radiator filler neck
with coolant, and install the radiator cap.
- Check the cooling system for leaks.
- Start the engine, warm up the engine throughly, then stop the
engine.
- Check the coolant level after the engine cools down. Add
coolant up to the bottom of the radiator filler neck.

SPARK PLUG

The standard spark plug is a shown in the table.
Spark plug should have a specified gap, and be tightened to 27 N-
m. (20FT.LBS).

NGK CR8 E o DENSO U24ESR-N
The spark plug should be taken out periodically to check its gap
and ceramic insulator. If the plug is oily or has carbon build up on
it, clean it (preferably with a (sandblaster) and then clean off any
abrasive particles. The plug may also be cleaned using a high flash-
point solvent and a wire brush or other suitable tool. Measure the
gap with a wire-type thickness gauge, and adjust the gap, if incorrect,
by bending the outer electrode. If the spark plug electrodes are
corroded or damaged, or if insulator is cracked, replace the plug.
Inspect every 30 hours and replace every 60 hours.
To find out whether the right temperature plug is being used, pull it
out and examine 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 burned whit, the plug should
be replaced with the next colder plug. If the ceramic is black, the
plug should be replaced with the next hotter plug.
If the engine performance drops, replace the spark plug first to
regain performance.

TRANSMISSION

For the transmission and clutch to function properly, maintain the oil
level at the proper level. Change the oil periodically. Oil at an
insufficient level deteriorates and contaminates rapidly. This
accelerates wear and promotes premature failures.
