    Chinese CDI units can be bought for as little as £5 UK ATM. I stipped a unit similar to the one you had which also had ceramic filling. It would not cut with a hacksaw so I soaked it in thinners for several days allowing it to be dismantled. The component's were of very poor quality so you can understand why they fail so easily.
    I have made several CDI units which were reliable but gave no improvement to the strength of the spark as it's governed by the power available to charge the CDI capacitor. I didn't use a drilled PCB but simply stuck small squares of PCB to a back board to mount the component's to.
    My 50cc engine produces 120VAC at tick over dropping to 50VAC @ 35mA at maximum revs.
    Thanks' for your video's Chris.

      Hi, Only CDI units with microcontrollers have advanced ignition timing, while the others only have different spark power with limited timing advancement, ranging between 5000 and 12000.
      In the future, if I can, I will design an advanced model and share it.

      @@MrWolfDiy Original cdi units for bikes up to 1995 have analog integration circuitry that is used for spark advance. They also have spark retard to prevent kickback on kickstarted models. It might be easier to go that route, because i have had lot's of microcontrollers fail way too quickly in high impulse currents environment...

    • @MrWolfDiy
      @MrWolfDiy  15 วันที่ผ่านมา

      It depends on the type of your motorcycle. If your stator is AC with one trigger, you can use a dtsi CDI, which I haven't made yet.
      You can also use a separate CDI for each cylinder.
      However, if your stator is DC, you need to use a DC CDI. I made a video in two parts on this topic. (DC)The first part explains how to build it, and in the second part, I explain how to install it on multi-cylinder motorcycles.
      Give me more details about your motorcycle so i can see what might work best for you.

  • @Herr_Bone

    Many CDIs have a function to limit the rpm of the engine - and thus the speed of the bike. It would be interesting to find replacement CDIs that do not have this throttle function. Maybe you want to talk about tuning options in another video.

    • @MrWolfDiy
      @MrWolfDiy  15 วันที่ผ่านมา

      Based on your situation, I have two guesses:
      First, the issue is likely related to the immobilizer, and it might not recognize your new key.
      However, since you have power to the spark plugs and fuel is being delivered, there's also a possibility that the crankshaft position sensor is faulty. If this component or the timing belt in your vehicle is damaged, it would cause exactly this kind of problem.
      Check it and let me know.

      There are some types of CDIs where the components are visible on the back of the CDI, showing a large number of parts and has a low price , However the main circuit operates with just a few basic components and while the rest are unnecessary...
      In fact, a CDI with those components and a microcontroller is both expensive and provides excellent ignition timing advance...
