    I did because the adjustments didn't seem to do anything. Never had any problems with my plugs mind you. Maybe I caught it before it got really bad.

      @calum So you just removed all 2 stroke oil from the tank and started to use premix?

      Not quite but it is easy to blank off the injection system properly and you can even buy plates to cover the missing oil pump. If i remember correctly you also need to up jet by something like 5% to allow for the oil being in the fuel.

        @jens-eskildsen not sure. I need to investigate. And how to do that? Full engine rebuild?

        Yes you'd have to strip the motor right down for those kind of checks but you could do a rebuild for maybe less than £500 including mains, crank, piston and rebore. This is a bit of a guess and with you doing the work yourself.

        If you remember to loosen the clutch nut whilst the engine is in the bike you only need a flywheel puller to strip the motor down. If you want to save the crank and not have to rebuild then a set of casing splitters would be a good idea but you can make these as well.

          Not sure if it is just the video but your bike looks like it's in reasonable condition with the body work all complete. Mines in bits now awaiting a full rebuild as it looked like it had come from Afghanistan not Italy when i got it home.

            @nottsbiker Thanks for advise. I have done top end rebuild with newly refurbished cylinder kit from Germany. Had a feeling that it is still something not right.

              @nottsbiker It came from France. About 25000 km on the clock.

                  Only thing that looks wrong with the TDR compared to the DTR is how low the back end sits. I think that the shock is either shorter or the dog bones are different.

                  Bike looks great btw 🙂

                          @nottsbiker I was trying to search for these plates. Where did you see it? Could you please send me the link how it looks like.

                            What plates are you on about? Do you mean the Jack up plates then I think it's either DTR shock or links (dog bones) to raise the rear end

                                      Mybelgarda oil pump failed and couldn't be adjusted. It just rinsed oil.

                                      I went premix in the end.

                                      @calum Hi. Did you change jetting after when you went for premix? If changed then could you remember what sizes for pilot jet and main jet. Thank you

                                        @tdrnoob I ran a completely different carburetor, so all my jet sizes would have been changed.

                                        Plus I ran far from standard settings. Jetting must done to suit the machine you are riding, no two machines are the same so jetting is best done to accommodate this.

                                          @calum I have found the details of my carb it is

                                          PHBH28 Dellorto carb

                                          main: 142
                                          choke: 60
                                          atomiser: 266d
                                          needle: x18
                                          pilot :45

                                          I have removed the oil pump and installed the plate cover for hole. Tomorrow engine is coming back after bottom rebuild. Just thinking should I change jetting. Any advice
