DT125R FORUM

been over it again today still no joy time to send the cdi for a test it's a strange one that yours works with one and not the other
i've seen one with the same symptoms and it was cdi and others say side stand or broken wire in the loom its only £40 to get the cdi tested so thats my next step if you do figure it out please let me know

i have read somewhere that a broken wire in the loom will cause it to spark with ignition off i've tested the loom on and off the bike but all seems ok

yes i had everything stock every thing tests ok but still the same problem
i was trying to eliminate the switches

done all that bud looped the side stand switch kill switch and 2 loops in the ignition block
i remove the loop on the kill switch no spark so thats good
i remove the loop in the ignition block ( blue\white & blue\yellow ) no spark so good but as soon as i remove the main loop ( red & brown ) spark returns (that would be ignition & kill switch in the off position)

hi i know its a long shot anyone know which wire tends to be broken

Hi nice to be here it's a UK 1999 dt125r with a 3rm-20 cdi only 17k on the clock with 9 owners so not a bad start it was bought as a none runner with no spark but the first issue i have found there is a spark ( thought i was on to a winner )but all the time with ignition and all kill switches disconnected i have been reading a few old posts all seem to point to a broken wire then i have discovered there isn't a side stand relay just a grubby melted 4 pin plug ive cut the plug of to replace and get a relay and guess what ive lost the bloody plug has anyone got a pic of the plug with the wires going in so i can get them back in the right order thanks guys and gals
