Question about Derbi Cross city Motorcycles
Hi, Mohamed_oda if your headlight is not working, keeps burning out or is dim the first thing you need to check is the headlight bulb for damaged filaments then check your light circuit fuse, that being said the usual suspects are:
1. Faulty ground or power supply wire to headlight bulb socket.
2. Worn, chaffed, or broken wires in the light circuit.
3. Corroded, broken, or loose pins/sockets in wire connectors.
4. Faulty hi/lo beam switch.
5. Faulty ignition switch.
6. Fuse is good but no continuity on both sides.
7. Faulty wiring between battery positive and headlight bulb socket.
8. Weak charging alternator/generator.
9. Faulty voltage regulator/rectifier, overcharging.

first have the head trued at a machine shop then get new head bolts, clean mating surfaces spotless with a non residue cleaner such as brake clean DO NOT TOUCH ANY SURFACE AS YOUR FINGERS LEAVE DEPOSITS that includes the gasket, torque to manufacturer spec with lightly oiled bolts,

There is a pickup coil inside the flywheel that powers the indicators and lights. At low rpm not much power is generated so the lights are dim. Increase the rpm's and more power is generated thus brightening the lights. This is normal on a small bike especially since it has a small battery. How old is the battery? They are only good for about two years. This could be the problem on the starter, weak battery. Also, check the fuses with a multimeter. A blown fuse will kill a starter every time. The speedo problem sounds like a crossed wire connection.
