could be weak battery or bad terminals, on the solonoid cross the 2 bolts, careful it will spak does that turn the starter, if so then its a corroded connect check all connections remebering the battery earth to engine. to check battery your need a volt meter, it should read 12.8v or more any less and the solenoid will just click

I have a 1999 Gilera Runner 180FXR, New bat 12V 9 amps. Starter turns and spins pinion gear but won't engage starter ring. If it does it turns ver slow or won't turn engine over. In manual it

Yep, not enough amps to engage the starter clutch, and when ti does engage, not enough amps to turn the engine. You need a 12 amp battery.

Does the gilera sc125 have a oil filter?

The Gilera SC125 does not have an oil filter, the two stroke oil from the oil tank lubricates the engine by injection into the inlet with the petrol. The oil in the engine is only for the gearbox and clutch. If you want to change this drain it by removing the drain plug underneath the engine, refit the plug and refill with the correct quantity of motorcycle gearbox oil or good quality engine oil. do not use an EP rated oil or the clutch will slip.

The dna 125 wont start

Hi and welcome to FixYa,

Initially, is there an alarm/immobilizer? If yes is it active/enabled?

Offhand, by "...wont start..." do you mean starter motor will not spin or engine turns but will not fire?

Starter motor will not turn:
  • press start button, check for +12 on green/black wire from starter switch to starter relay;
  • if there is, is there a clicking sound?
  • if there is a clicking sound, short temporarily the 2 big terminals of the starter relay;
  • if starter motor turns, starter relay faulty;
  • if not, starter motor needs looking into particularly the carbon brushes and the commutator segments.

Starter motor turns but no spark:
  • check/replace sparkplug;
  • check pulsating voltage on green/white wire going to ignition coil coming from the ignition control unit;
  • check pulsating low AC voltage on green wire going to ignition control unit coming from the pulse generator coil;
  • check presence of IGN +12 leading to the ignition control unit.

Starter motor turns, there is spark but motor will not run:
  • check automatic choke (blue & white/black wires);
  • check fuel quality and quantity delivered to combustion chamber (check sparkplug if wet).

Good luck and thank you for asking FixYa.
