    Oh okay interesting, are you able to fit a kick start and ditch the starter motor? The DTRE has a starter so maybe that frame is a better fit.

      It has the kick starter shaft too, so I can just fit that if I want, but I want the electric starter.
      The bushing for the mount under the swing arm is abt 1mm too long, so I had to grind off abt 0,5mm on each side of that one.
      The intake has an enormous mounting diameter for the carb, so I ordered both a Cr125 and (hopefully) a smaller version of the DT230 intake. CR125 VF4 drops straight in, but might obscure the boost port too much. I have no plan to run e mega carb. I think 30-34mm should be enough.
      I have taken off the cylinder now, and will measure the engine and simulate it in EngMod2T later on.
      Expect no pictures here, because I don't use the image hosting services that go away, ransom your pictures etc.. (if you know, you know). I did put up some pictures in the Swedish DT125 FB-group.

        @Rallyfinnen It's annoying that images get ransomed. I simply don't have the bandwidth HDD space and/or money to host images.

        That said, I have migrated my images to the server so that the issue of images being ransomed goes away for me.

        Oh that's really awesome. I certainly hope it works out for you though. I think I'm done with the DTR platform for the time being and am concerned with my RD at the moment. But I am building an LC motor which one day may be transplanted into a DTR chassis...

          Hard to get tuning parts for the LC engines though! I have a modified Athena 170 on a DT LC engine, It was all I could think of. Welded on a reed inlet on the cylinder to get a cylinder reed. Had to send it for re-plating after that, because it was warped during welding. Runs about the same as the DTR which also has the Athena 170 for now (until I transplant the 230 engine). It's a custom build DT LC 'supermoto style' with a low slung exhaust and 18" wheels front and rear. Yamaha competition yellow with some DYI side fairings and graphics. I named it DTX. Put a lot of work (and money) on that one this winter!

              As a swede who recently have ogled DT200's and Lanzas for sale in Greece, pondering if a trip down with a small lorry is too big a venture, I find this HIGHLY interesting. Please keep us updated!

                Join the 'Yamaha DT125 Sverige' FB group, I try to update my post with some pictures from time to time. Plan is to get it running before the end of my vacation, in two weeks.

                    By the way - this seems to be the most frequented site for looking at DT200/230 bikes and parts in Greece. I am not sure, but I think it was the only market in EU where they were sold.

                      Would be quite a project to get one from Greece, picking it up, registration etc, probably a renovation too. It will be an expensive bike, but on the other hand, it can probably be sold for a higher price than a converted 125! If they get's too expensive, I'm reluctant to ride them because I might get a scratch etc. I thought they sold some in France too, but maybe not..
