Radiator; Strip Box - GAS GAS HALLEY 125 SM/EC 09 User Manual

The proper working of the engine depends on the good condition of
the sparking plug; therefore, this is an extremely important component
that can be easily inspected. Disassemble and check the sparking
plug periodically. For instance, if the central-electrode porcelain
insulation appears to be too white, this might be due to a leak in the
carburettor air-intake tube, or to carburettor damage or malfunction.
The high temperatures the electrode is subjected to, together with
carbon deposits, result in excessive wear and eventually render it
useless. When this stage is reached, replace the sparking plug with
a new one of the same type and recommended thermal grade (Denso
W27 ESR-U), or any other brand of a similar thermal grade.
Carburettors must always be checked by an authorized GAS GAS
dealer.

mind is that of ensuring that it
is completely full of liquid, since,
in this way, the water is
guaranteed to complete the
whole circuit. The use of closed
circuit antifreeze liquid is
strongly recommended. In this
way the you avoid the freezing
of the water with the attendant
risks engine seizures or
breakages of the pump blades.
