About CDiS

Let's take a brief look at the subject of CDI. Why should you replace a CDI? There can be a number of reasons for this: - Your scooter suddenly stops in the middle of a trip and doesn't start again afterwards. (electric starter does nothing.) - Your scooter won't start anymore. - You want to return or boost your scooter.

First of all, the difference between the CDs of two-stroke scooters and those of four-stroke scooters:

A CDI has no influence on the scooter's top speed when it comes to a two-stroke. In the case of a four-stroke, a CDI does influence the scooter's top speed. With a four-stroke, a CDI therefore affects top speed, but this is not the only factor. Top speed also has to do with things like your variator ring or gasoline air adjustment. So if your scooter runs 60 km/h, for example, it doesn't mean you can run it 45 km/h again just by replacing the CDI. So always keep that in mind!

Assembly and return

It is also necessary to connect all CDI cables, which are of course attached for good reason. Otherwise, the CDI will most likely not receive a good power supply and will therefore not work. In addition, all CDs are new and are tested to function in the factory and are only shipped if they are fully functional. So it never happens that a defective CDI has been sent to you. It is also the case that some scooters combine the ignition coil and CDI in 1 part, so when these scooters stop working, it may be due to 2 parts. At the ignition coil or at the CDI, but because they are combined, both will no longer be able to do their jobs. Attention!! CDs cannot be returned because they are an electronic product. It is also the case when there is a short circuit in the scooter that this can immediately result in the “inflating” of the new CDI unit. So always make sure you're sure which CDI you need! You can always call the assembly helpline for advice, so you can always be sure you order the right CDI.
