              Hello,after a long time,it's a slow project due to some personal matters from time to time.
              "Last minute" tuning to crankcases for matching,widening,angles retaining and "little" tuning to Athena cylinder/head (trasnfer port shape and sizes,exhaust port shape,size and timing,combustion chamber volume,compression)

                      Thank you all.
                      Yes almost everything is painted,machined by me,only an custom axle-spacers for the front-back wheel and a welding back of the frame tail base because of a broken bolt was done to a machine shop.

                        This is the frame after the paint removal and acid treatment for the rust,then painted,before paint,cold zinc was applied to the frame for rust protection.That stage and the frame in original condition was lost in the data corruption.

                              Hello after a long time.
                              I had to open the crankcases because of a faulty gearbox part (even checked I've missed it).
                              Did some further tweaking to the cases,matched them 99+% I believe,and gave a texture to help flow and "grab" more mixture,widened a little the reed valve space and removed some metal from the low right corner for the RZ350 reed valve to be installed.

                                The finished DTZr,it's on the road,I am doing some runnin km's and will go to a friends dyno. 😀

                                Passed technical inspection with "flying colors".
                                I didn't put the 3ET headlight because it's no good for night,if you want to see and not just others to see you.

                                  Bike looks great and similar (not wheels) to my old DTR that I built years back (profile picture).

                                  I've just bought a 3ET light unit for my 200WR as I believe that they are the same so I'm gutted to hear that they are poor output but I want to go back to stock as the 125X unit I've got does come in white and therefore looks odd.

                                  Interesting that you've also gone down the 3ET swingarm route as I've got one ready to go on my 3SH build - great minds think alike! 🙂

                                        Finishing my modification of 80's YZ/RD/DT125 reedcage,to fit the DTZr.
                                        It is used because it has less pedals,it's shorter and doesn't block the C boost port of the cylinder the.Widened to fit the carb rubber joint,bolt holes relocated and smoothed the angles.

                                          @MadGyver Looks sick, I was wondering what the motivation behind this was.

                                          Be interested to know how this goes once it's all done! Keep up the work.
