Hi, Anonymous and the usual suspects are:
1. Fouled spark plugs.
2. Discharged battery, check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Loose connection at ignition coil or plug between ignition sensor and module.
4. Spark plug cables in bad condition, shorting / leaking, spark plug cable connections loose.
5. Faulty ignition coil or ignition / electronic module
6. Failed CKP, CMP, or BAS sensor.
7. Faulty ignition switch.
8. Security alarm failing to disarm needs reset

SOURCE: yamaha DT 125 2003 Main beam headlight keeps

i have well, had a very similar problem, my headlight kept going on my 1990 dt125r from 1990 to 2003 the engine is the same so i feel it may be the same fix, the regulator/rectifier stopped working properly and was alowying to much power to get to the headlight and blew it, i got a new regulator/rectifier for around £30 ish, you could tell when it went caus the higher you reved it the brighter the light got until it blew not like when it gets brighter from tickover, it was just proggesive and just kept getting brighter the more you revved it, hope this helps

Hi fit butcher,

The assembly of DT's speedo are all the same after 1998 models. below is a picture of a 2002 DT125/175. the assembly is the same, only that yours does not have a tachometer, yet the placement of the assembly is the same.
