HELP 4dl/3MB-oo wiring
-
Hi, i'm swapping a 91 tzr 125 engine on a Aprilia RX 50 1995, i've made engine mounts, adapted a KTM 125 exaust and other stuff, so my problem Is: i have a 3mb-oo ignition (3 coils), and i want to get working Only the ignition coil for the Spark... Can anyone take a few pictures on our bikes of the CDI, stator wiring and ignition coil? I want to understand wich wires i should use...

@simork6 get yourself a Haynes manual it will have a wiring diagram. The coils are slightly different, but the engine is practically a DTRE engine.
I can't remember how I done it, but I probably used the stator and coils from the DTRE engine so I could use a more readily available ignition system with built in YPVS instead of the two independent systems that the older models had.

@simork6 hello and welcome, I recently bought a 2000 dt125r that had been stripped of all lights, clocks etc for off road use, wiring left in a bit of a mess. I got a wiring diagram for 2000 model and it clearly wasn't right. Turns out though the bike was registered in 2000 it was actually manufactured in 1999. Anyway the point I'm trying to make is Yamaha customer service were very helpful to me. I emailed them with the vin/frame number and engine number and they sent me a PDF of the full wiring diagram.

Good luck with getting the engine going and don't forget to let us all know how you get on and post some pics. Everybody on here loves to see pics.
want to post some pics to make the swap easier I know yours isn’t in a dt frame but still may help me
