How to de-restrict an electric scooter

Updated July 19, 2017

De-restricting your electric scooter will void its warranty, and operating a scooter at an accelerated speed increases the risk of harm to both the scooter and the driver. Should you decide to take the risk of de-restricting your scooter, you should know that the task is a two-part process. The first part of the process involves disabling the capacitor discharge ignition (CDI) unit. The CDI unit calculates the speed of the scooter's back tire and restricts the engine from operating at full throttle. The second part of the process involves raising the carburettor needle to allow more fuel into the carburettor.

Locate the CDI plug on the battery compartment. Remove the pink wire from the CDI plug.

Wrap the end of the pink wire with electrical tape.

Lift the scooter seat. Remove the two screws at the bottom of the storage compartment with a Philips screwdriver.

Slide the black rubber seal and the yellow disc off the exposed tube. These two pieces will come off together, as they are attached to each other.

Examine the parts between the rubber seal and the yellow disc. You should observe a spring, a white connector, a metal needle and two washers. Remove the larger, loose washer and set it aside. Use pliers to remove the second washer, as it fits snugly on the metal needle. Set the second washer aside.

Replace the smaller washer by sliding it onto the metal needle. User pliers to manoeuvre it down to the middle groove on the needle.

Slide the back rubber seal over the tube, then place the large washer over the rubber seal.

Insert the metal needle into the hole in the tube, then insert the white plastic connector into the tube.

Insert the spring into the tube to complete the reassembly process.
