Hi all, first post so go easy.

Passed my CBT and then went out and bought myself a 2002 DT125r, Electric start only covered 2000km. As you can imagine as i had just passed my CBT i was on it every day for about 3 weeks, it worked flawlessly. I noted that the front head light had stopped working, so got myself another lamp and changed it. turned the key and it didn't work, so tried starting it, Nothing. The Engine will turn over on the button, with good compression. Have tried cleaning the spark plug(iridium) and tried a new standard plug, with no effect. Fresh fuel, without the air filter, new coil, still to no avail. The wiring seems fine all plugs are clean and i can't see any bad connections. Any suggestions welcome.

Pull the plug and set it on the head and turn over the bike and see if you have spark.

If you dont have spark thing to check

resistor cap (spark plug cap) remove and test

power to coil test light or dvom key on,no power check kill switch and ignition switch.

Pick up coil

with no head light I would be looking at the ignition switch as the power for both are related.Also any wire you may have un pluged accidentaly when changing the lamp.
