    I appreciate the fixing but I haven't a clue what (www.example.com/image.jpg) means I'm afraid

      Wowee 69 european pounds for a shim then a cover a rotor and a stator, sounds like heaps of money to me.
      I will see what the whole lot is going to come to and go from there

        What did the bike cost?…

        When you’ve hosted a pic at Imgur, or whatever. At the top of your post, on the tool bar, there is an oblong that looks like a picture frame with 2 mountains and a star (between the 2 chain links and the smiley face) Tap that then paste in the ‘copy link’ from Imgur. It will show your pics…

                Gonna be a couple hundred quid. The feabay seller problem has the rotor. The shims the fuxor! Can’t be easy to make that puppy though!…

                Still a viable bike if it’s in good enough condition…

                  The copied link has to go between the ( ) brackets

                  Make sure the ‘image url’ is deleted if the paste doesn’t go smoothly. Otherwise I’ll corrupt…

                              Before my time 🫤 RD 250?…

                              Edit: 200?

                              I met a bloke who put an RD 200 twin engine in a dtr125 frame! He was trying to make a 2>1 exhaust the last time I saw him. I didn’t know about 2T expansion chambers at the time! I’ll have to stop by and see what’s what next time the weathers good and I feel any kinda sociable…

                                    @mcludd Here's a 3NC wiring diagram. The DTR used either 3NC or 3MB wiring between 1989 and about 1998; 3MB is almost identical but you can't run a 3NC CDI on a 3MB loom or vice versa.

                                    alt text

                                    I don't know very much about the '99 onwards wiring which incorporates the reed switch etc but the 3NC and 3MB platforms (and the 3DB from the original round slide carb DTR in 1988) are all full power, even on UK bikes which were just supplied without the YPVS servo and the powervalve pinned closed for the 12bhp learner legislation of the day. I'd steer clear of 3DB electrical parts as the '88 bike had a different bore and stroke to '89 onwards DTRs.

                                    To run 3NC or 3MB electrics, of the top of my head you'd need:
                                    CDI unit and main loom
                                    Stator and flywheel (part numbers are different between 3NC and 3MB)
                                    Non-DTRe crankshaft if your bike has electric start
                                    Regulator/rectifier
                                    3-wire YPVS servo (the 3-wire servo has its own on-board computer and so only requires an RPM signal from 3DB/3NC/3MB CDI units)
                                    Pattern 6-wire ignition switch
                                    Left handlebar switch cluster
                                    Clocks for temp gauge wiring
                                    Twistgrip (the type with integral kill switch)
                                    Poss. sidestand switch

                                    These electrical platforms are a good deal simpler than some of the later bikes and as far as I'm aware the left crankcase has all the correct mounting holes for the non-DTRe stator even on electric start bikes so if you can get hold of all the above parts it could be the easiest way around this. Also if you look around, back in the day there was such a thing as a 3MB DTRe which would be the best electrical platform to go for IMO if you wanted to do this. At one time I owned three French import DTRs; '93 and '98 3NCs and a '98 3MB. All full power (10k rpm +) but the 3MB had noticeably more power than the other two despite having over 65000km on the clock (the 3NC and 3MB have different ignition advance curves).

                                    The KTM LC2 125 had a DTR engine and ran the 3MB electrical platform so have a look on eBay international for a CDI and servo off one of those, German and Austrian breakers are full of them.

                                    Anyone can see anything I've left out please feel free to add to this!

At one time I owned three French import DTRs; '93 and '98 3NCs and a '98 3MB. All full power (10k rpm +) but the 3MB had noticeably more power than the other two despite having over 65000km on the clock (the 3NC and 3MB have different ignition advance curves).

                                        The KTM LC2 125 had a DTR engine and ran the 3MB electrical platform so have a look on eBay international for a CDI and servo off one of those, German and Austrian breakers are full of them.

                                        Anyone can see anything I've left out please feel free to add to this!

                                        It’s all bloody expensive, if you can even find it. Fleabay 3 wires are at about £180 last I looked. Also looms are from there upwards!🙂

                                          @mcludd No worries bud 🙂

                                          @SpookDog Yes, all a bit pricey these days and finding a non-butchered 3NC or 3MB loom is the biggest challenge. Saying that Zeeltronic sell all the correct connectors so with a decent crimping tool you could probably make your own for roughly the same cost as buying a used one.
