    Took so many attempts to get the starting circuit to work. Checked everything, earths, relays, switches, batteries, motor and cables.

    The first lithium battery I bought was total crap, couldn't crank the engine over even though cross reference numbers said it was correct. Bought a shido and works perfectly.

    Made a numbplate holder + front "number plate"

    The most exciting part is the exhaust! Cut off about 10kg of the baffles. Shortened the silencers right down and made up the end covers.

                    @Louis-DT-WR very cool looking bike mate. You have a cool helmet design to go with it? Something like a skull with bullet holes would go well with that bike.

                        @Louis-DT-WR hard choice to make I like all 3. That bike is going to be a good conversation starter. Sure will get some attention.

                          @markus-w I like the bottom one but looks too modern.
                          Yes anyone who gets the refe of Lucille will.

                            When you buy exhaust wrap, they always rip you off and send you much less 😠

                            Got one half of the exhaust done.
                            The fiberglass gets everywhere πŸ˜….
                            Cleaned and Sprayed up the rusty bits silver.
                            The wrapped from the silencer to the flanges.
                            Heat shields Powder coated black

                            Engine guards didn't come with any instructions and can't get both sides to fit yet with the brackets that came... Probably have to make more.

                              Finally got the exhaust done.
                              A few final checks and some cosmetic parts then it's show time.

                                  Congrats! It’s nice to see someone doing their own thing! Nearly every ride I’ve ever had has been a butchers tripe mix of a thing. Mostly through necessity though! πŸ™„
                                  I’d really love to do a street tracker out of an old Honda CB 200 twin. Nice & lite yet revvy & torquey enough. Think of Girl with the dragon tattoos bike with attitude ☠️
                                  They aren’t easy to find anymore though...

                                      I'm not very familiar with this bike or twin terminal coils.

                                      Bike won't start, I believe it's electrical problem.
                                      No spark.

                                      The CDI I bought might be the problem.

                                      On the coil it has 2 electrical connectors (both +) and earth's to chassis.

                                      Ignition on and kill switch to run the voltage on 1 terminal (yellow and blue wire) to both coils has 12v.

                                      But there nothing on the other 2 black / white wires. Not even when cranking over.
                                      Surely there should be 12v to both terminals?

                                        Depends where you are measuring from. The coils job is to take the 12V DC and step it up to 20KV. So you measuring at 12V is outside the scopes range.

                                        12V isn't enough to jump the spark plug gap.

                                        Measuring Coils is usually done through impedance test on the primary to secondary, secondary to spark plug cap. Should fall within the tolerances outlined by the manufacturer.
