    @bradt I just levered it out with a small flat head cleaned up then pushed the other in I didn’t do nothing special but taking out the shaft is sensible just not for me

      Id just replace it aswell, its pretty common to do, And I've done so many times on other bikes, both for the gear selector shaft, and the main output shaft.

            So iv fell massively behind new job etc house problems the list goes on

            But we’re not far off
            New job means this is going to be a daily user for work so need it back on the road and sorted until I get a company car

            Another things is there anyone close to Sheffield or willing to travel for abit of light off-roading in the Peak District or just general meeting ?

                Is that what you want to do is it, use it as a daily work horse?

                Mine never let me down. Great commuter.

                  When I first started rebuilding it wasn’t the idea was just gunna be a weekend toy have a good blast around every now and again but things change so until I get my company car it will be used
                  But with it nearly finished it’s not the best build and not the cleanest and already pricing everything up for a full nut and bolt rebuild and making everything original to keep its value but that’s a long way off

                  Already keeping my eyes open for something else for a project something I don’t need to use as really enjoyed doing this.

                      @bradt best way is to run premix in your bike while running with the autolube full bleed the lines there will be a rubber blanking cap on the pump pull that off While the bike is running on premix and when the air bubbles stop coming out plug it back up then watch the flow coming from the pump to engine best use clear lines so you can see the air bubbles then when there’s no bubbles your good to switch back to autolube fully

                        Cheers mate ordered some clear lines

                        Bike all ready now, but have noticed a leak from the carb guessing bowl gasket needs replacing

                        Auto lube needs bleeding also and she ready for her first start

                        First time out the garage in a few months quick wipe down and a polish

                                @bradt Literally go and make one.

                                Go to Halfrauds or a MotorWorld and just buy gasket paper.

                                  So will try gasket paper as silicone has stopped the leak but still seems like I’m not getting fuel to the spark ? Anything else I need to check ? All carb was cleaned out new filter in there etc getting abit stressed now

                                    This is a lot harder without electric start working so having to bump the bike every time I try and start it

                                      Does anyone know where the black wire (I’m guess an earth) on the coil is meant to go

                                      Iv just fitted a new startermotor to the build makes it easier to start and found I have no coil

                                      Noticed the black wire with hook was connected to the coil itself should this be earthed to frame or is this right ?

                                        The starter motor has a red wire only which connects to the starter solenoid (this is the square thing with two fuses in it by the battery). There is a black wire with a hook which connects to the neutral switch which is located near to the starter motor at the bottom of the engine casing on the flywheel side. this in turn plugs into the part of the loom which goes into the stator/generator coil via a bullet connector. Hope this helps.

                                          @2Stroke4Smoke very helpful went through all wire and found a broken wire replaced and fixed nice bright sparks and fired up
