      My 1998 DT125R was running fine until i was trying out some different carbs and once it went something like boom/pop when it was idling. No spark after that. I have tried out different spark plugs, known-working coil with HT lead, replugging all the connections on the bike. I have also tested the ignition switch, sidestand switch and kill-switch and they are all fine. The only fuse my bike has is the one inline with battery and that is fine. My bike has 3RMA CDI, but i don't have a way to test this one.
      I also tested the pickup coil next to generator. Is it supposed to have continuity on the 2 leads? Mine does not.
      The screen of my speedometer does turn on when i try to start the bike, so it generates some electricity at least.
      Any ideas?

        @Krenop check the pulse coil resistance, there should be between 280 & 420 ohms

          @tdrpaul Infinite resistance, so it is probably dead. They are really hard to find and very expensive.

            @Krenop will this do https://www.catalyst-findit.co.uk/index.php?c=d2f5d910014f2842ada1bbc16c273aae&vat=ex&dest=prod&p=128&pid=44-0931&PHPSESSID=r1jmm443jg5cn6a67i8a24p1q7

            Or there's this http://www.ebay.co.uk/itm/dt125r-stator-/142027363056?hash=item21117d92f0:g:G4kAAOSwfC9XOXf9

            The first one looks like it should fit ? It only picks up a difference in magnetism when the raised part of flywheel passes it.
