    Hello.

    I just bought myself a new Yamaha dt 125 r, and i want to derestrict it. But when i looked at the derestriction guide and then at my bike, the cdi wire colors were different. And I've been searching for a other guide to derestrict it but there is none.
    When I'm in the last gear the bike won't go over 80 km/h. If it goes i can hear the spark plug not getting spark and getting spark when its back at 80 km/h.
    If anyone could help me, it would be appreciated.

        @forum members
        Isn’t there a later model that needs a CDI wire cutting & earthing somewhere? Or is that a Tzr?…

        I’m sorry Mr-Shadi, I don’t know too much about later than 1995 model dtr125’s, other than what I have read. What country is your bike from? I’m guessing that english isn’t your first language?
        I’ll do a bit of reading and try to find out about 1997 bikes…

        Edit: 4dl Germany! Got it!

            The DTRE has a green and black wire, once earthed that's all the electrical restrictions and then the bike revs off the clocks.

              I’m worried that he might have the one with the ‘silver box behind the 2T oil tank’ that needs loads of faffing about! I tried getting scrims guide up but kept getting a 401 error!…

                @SpookDog 401? That's Unauthorized

                Right, yeah I don't know about that one. I only really researched the one for my bike.

                Best thing to do is get a Zeeltronic ignition system for it and you're laughing.

                  On a copy (of scrims) on another site it said to install an earlier CDI I think? Yamaha certainly had it in in for you lads with later bikes! Access Forbidden! 😛 SNAFU! ☠️ …

                  My bad! It was 404 not quite as verboten! 😎 …

                    Yeah that makes more sense 404 - Not Found. I think you'll find 403 is Forbidden @SpookDog

                      @SpookDog i don't seem to have a silver box behind the oil tank. The only silverish/grayish box is the voltage regulator.

                              @Mr-Shadi Sure, but some models of DTRs were heavily restricted via the CDI, so you're literally gimped until you replace it with either a less restrictive CDI or an aftermarket one.

                                  Seen a few 3nc’s on eBay lately for reasonable prices. I got one for about £30 a while back…

                                  Still not convinced you need one yet. Try and find a copy of scrims write up. I found one the other day, I’ll try and get an address…

                                        I'd just get a Zeeltronic and be done with it.

                                          @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?
