    @SpookDog it's not even mentioned in the manual about not removing the left-hand pulse generator cover on the sidestand 🤷‍♂️

      I have no idea when I use the shrug emoji it changes it to a girl and the gender symbol 😂

      After further investigation... My cdi which was sold by a bike breaker written in white paint "cb750 1997" ... I cleaned off the paint carefully and the part number just about readable is

      MASG G
      571U

      Which is a cbr900!!!

      Whether or not that's a problem, I've got another one from another spares breaker with the correct part number for the cb750 sevenfifty

          Same here. Should be beasty.
          I knew the electrics would be the hardest part.
          All lights and horn was easy.
          Starter circuit was ok.
          Just the ignition circuit 😁

            It WILL fire up with a new CDI, unfortunately online buying is a fukin shark feeding frenzy of a$$hol£s all caring about one thing. The amount of times I’ve been shafted on fleabay is unreal. Brought a headlight that came without the bulb holder or rubber, the bloke had the neck to tell me that I was confusing his with another listing, conveniently after his pics were down. The only reason I nodded was cause it was complete...
            Another bloke changed the listing twice while I was between messaging. Once to up the price £40 then to change from 3 wire to 5wire servo! Same listing number an all...

              @SpookDog I know the feeling. Many sellers have lots of similar items for sale but send the wrong ones.
              The problem is I built this bike with parts from about 30 bikes... And no real way to test it will work together until I try

                  She runs and runs beautiful!
                  I'll do a video when fully warmed up.
                  And not pouring rain.

                  It was screeching when I started it., Originally thought it was the starter, but when running it was awfully loud. I thought "here we go" something major.
                  I had a suspicion it was the generator....
                  Look what I found...
                  A tiny recess where a slightly bent fan blade was rubbing the cover.

                  Really easy fix and now sounds great!

                              @NINJA it is very beastly sounding if I say so😁 I didn't know what to expect. Definitely will wear ear defenders next time

                                I know it's not the same, but my RS is too loud for prolonged use without ear plugs. My ears are literally ringing from the noise. I am a sensitive lad though.

                                  @Calum we all like a noisy exhaust until you ride a long journey with one, then it just gets annoying

                                      Agreed. I prefer quiet engines that make power. Turbo Flutter is a must.

                                      Now an eargasm superbike inline 4 that's a win.

                                      But I can't stand loud Hondas that make fack all power.

                                          @Louis-DT-WR Not being funny, my Starlet wouldn't pull with four kids in it and that's actually a rapid motor. I mean it's no Skyline but it's still 133hp out of a 1.3 860Kgs from 1989.
