    @nottsbiker Hi. You wrote earlier to increase the jetting by 5%. It has pilot jet and main jet so do you mean those two to change to higher ones by 5%?

    I will test the bike with the original ones first

    I'm not an expert on jetting just relaying what I'd read years back. If in doubt get it set up by a tuner

      Ps I've picked up a complete pdf of the 3SH parts list with full pictures and Yamaha part numbers from the German TDR forum.

      I'm currently in France on holiday but can email it to you when I'm near some wifi if it's any use to you?

          @Nottsbiker is there many pages? It would be great if we can get them uploaded into a thread of their own.

              Quick update

              So my TDR belgarda had a full engine rebuild by Roadrunners motorcycles.

              Also I have started premix. I used about 35 ml of 2 stroke oil to mix with the petrol.

              There is video

              https://www.youtube.com/watch?v=gjEHSmpNIgg

              What do you think guys?

              Just wondering if it everything ok.

                I used 200ml oil to a full tanks. Approx 10 litres.

                Lovely little whistle to that engine too. Sounds great.

                    Sounds a bit chirpy? Can't think what would cause that, unless its just the recording

                        Looks like you are making good progress though mate 🙂

                                  @oldman I have changed the old seat cover with the new blue leather. It is not perfect fitted as I couldn't stretch properly where is angle.

                                  Pretty happy with this blue color

                                    @zrako Yes, it looks like is the same thing with mine.

                                    Have you fixed that or just ignored?

                                      @tdrnoob first thing I did was removed starter motor to see if its really that problem and it was. I had a broked bearing stay. Thats a plate behind a flywheel where starter clutch sits on needle bearing . I am replaced it , cleaned and lubed everything in there and its ok now.

                                          @nottsbiker Not sure if it is tight as it is my first bike 😕

                                          Also I have changed the old air filter and cleaned the carb properly.

                                          Good progress because of wanting to ride and commute to work.

                                          I bought it back in may and since then made only 100 miles.
