    @Mr-Shadi

    It might be a different colour on account of the weird RN thing…

    From what I’ve read people move the reed switch then cut & earth a black/green wire…

      @SpookDog i think if i take the other bikes wiring diagram with black green and then my wiring diagram and then determine witch wire does what. like compare the wire colors for example its bike has red wire as power mine has orange. just a example not reality.

        Hang on bud! Your bike is a Dt125RN you said? Did you mean a Dtr125 3rn? This would make more sense! 🙄

          Just counted CDI wires on the 3rn diagram in my Haynes manual and it says 11 wires from the CDI. How many have you got?…
          I’m just curious cause it doesn’t show the reed switch or any wiring to the speedo on the diagram, guess they wouldn’t show the restriction though! 🙂 …

            @SpookDog it has 18 wires. 3 cdi connectors with 6 wires each.

              @SpookDog i also looked under the speedo and there is a white little box with blue and green red wire coming out of it. i tought it was a light but when i looked it had a little space between 2 metal thingies in it and it was covered with glass. Is that the reed switch?

              @Mr-Shadi this is a reed switch. If you look at it, it looks to be a broken fuse. When the speedo hits 61 mph it sends an electro magnetic signal and closes the switch which retards the ignition and closes the powervalve back up. Either move it far away from the clocks so the magnet can't reach it or cut it off and keep the wires apart.

                @markus-w if i cut it off the bike wount rev over 6k and if i move it it randomly restricts it to 6k rpm. then i need to come to a stop and it revs over 6k.

                          I’ll look for a 4bl (I’ve never heard of a 4BL, you sure it’s not 4DL?) wiring diagram…

                          It is bl just checked

                            What colour is the wire going to the reed switch? Also what colour wire returns from it, if different?…

                            is it red/blue?! with a white/black wire returning?!

                              @Mr-Shadi i moved the reed switch, cut wires and did a lot of things but when the reed is out of its slot the bike won't rev over 6k in 2nd 3rd 4th 5th and 6th gear, but when the reed is in its slot it only doesn't rev when 80km/h. I even pulled the reed out a little bit and it didnt rev over 6k. Very weird

                              @Mr-Shadi you have the 4BL model, that's the later one with the reed switch but I guess you must have the restricted 3RM-10 CDI?

                                    @markus-w it has a restricted cdi but its weird that if i move the reed switch at all it dosent rev over 6k. and i was thinking if i cut the wires and leave the reed switch in its place without the wires, maybe it will work.

                                      @Mr-Shadi i searched for wiring diagrams and i found one very pixelated one that showed the reed switch and its just 2 wires that go in to the cdi with nothing in between and there were 18 wires.

                                        @Mr-Shadi

                                        Any progress?…

                                        It is weird that it activates if you move it away from its spot. Are there any other wires going into your speedometer apart from the read switch ones you’ve mentioned, and the two for the bulb? (blue & black on mine) I’m wondering if the ‘activator’ in the speedo is electrical or magnetic/mechanical in some way…

                                          @SpookDog I GOT IT! I derestricted it. It took me a long time and a lot of anger but i DID IT! I did it by cutting the reed switch wires and putting the reed switch in its place with exposed open wires. Then i turned the bike on and kickstarted it, after that i revved till it hit the rev limiter and connected the wires till the rev limiter passed 6.5K without staying stuck and taped up the wires so they don't touch (Not the wires that are on the reed switch. The ones that come to it) and put them away. now the bike accelerates beyond 80km/h 50mp/h.
