    @Mr-Shadi the 1997 doesn't have the reed switch. It has a restricted CDI. Maybe change it for the older 3nc CDI. But you should be getting a lot more than 80kmh. Something else isn't right for sure.

    @markus-w i can hear the spark plug not getting spark when it goes above 80 km/h. But it takes a a little while for it to start not getting spark (3 to 7 seconds). And when i disconnected one of three cdi wire connectors and went on the road to try again. The restrictor sound was different and started right after 80km/h with no delay, unlike if the connector was connected.

      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.

                @Calum

                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…

                                        That’s not even 60mph! Damn! I did think that you might have one of the’stranger’ ones. I still think that scrims deristricting guide is your best bet…

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