First of all, disconnect the minus tick from the battery. The air filter must then be removed to allow easy access to the controller. After that, release the retainer and remove the wire with the wires from RXX. Take the BRAX T20 key and unwind the two lines connecting the throttle control to the throttle and then remove the RXX.
Before you install the new governor, you should clean the installation site in the throttle. You should also take a new sealings ring and put some engine oil on it. The new governor must be installed in reverse order.
