    Not firing up...

    Switched 12v to red and top of coils, coils jumped together at this connection.

    White to 1&4

    Where do those two white/black wires go to?

        I saw that the first time. Is the white/black that is on the top screw of the right hand coil attached to the black wire, I see the white wire. Is the white/black wire on the bottom screw of the left coil attached to the Dyna red wire?

          I can't see what you have done outside of your pictures. If it is the way I think in my second question, it should start if you are close on the timing. It will not start if your battery is 11V or lower.

            I ran 12v switched to red wire on ignition, and to both coils (top connection now, was on lower)

            I didnt have enough white and black wire so i had to use what was available (wht/blk) you cant see but they are labeled. 1&4 coil is connected to the white wire on ignition and 2&3 is connected to the black wire of ignition. She fired! Not exactly sure what was wrong as i measured 12.5v at the battery before putting it on charger...

            How to i time it as i have no marks??

                That's good enough to get it running nicely, but you should time it with a light. I never found one where 2-3 was spot on and have always had to slightly slip the module on it's bolts to get it exact. A timing light will also tell you if your mechanical advance is working properly. If you bypassed your kill switch, you might want to rethink that and do a coil relay mod. Those gas caps leak when the bike is down, a kill switch looks pretty good then.

                  Thanks for the assistance. Runs pretty good, i have to check 2&3 forgot to do that. I did the relay mod some time ago, and ive got a killswitch as well.

                    definite performance boost with the dyna ignition, wires and coils! Next, save money for a new rec/reg....
