Mechanical governors are any devices that regulate the operating speed of a machine, specifically an engine. Unlike larger vehicles, scooters possess a relatively simple mechanical governor, which takes the form of a washer placed in the scooter's variator system. Removing this washer from the variator ostensibly removes the scooter's governor. Removing your scooter's governor washer from the variator system removes the operating speed regulations for your scooter's engine, allowing your scooter to travel faster.

Step 1

Remove the kick stand. Pull the pin attaching the scooter to the variator box up and out and then pull the kick stand off of the box. Set the kick stand aside.

Step 2

Unscrew and remove the two bolts holding the plastic cover of the intake box if your scooter has one. Some scooters do not have this covering, in which case you can directly access the variator box from the outside of the scooter.

Step 3

Unscrew and remove the bolts of the variator case lid. There are six bolts around the edge of the box. Three of the bolts are on the top of the box, three are on the bottom.

Step 4

Crack the bolt holding the faceplate of the front pulley wheel with a socket wrench or an impact wrench. You will need to secure the front wheel while cracking the bolt if you use a socket wrench. You can use a strap wrench to hold it in place.

Step 5

Unscrew and remove the bolt from the faceplate of the front pulley wheel. The bolt will have two other pieces attached to it, a spacing washer and a metal device that looks somewhat like a washer. This devices connects the scooter's starter to the variator. Keep these pieces together exactly as they were when connected.

Step 6

Take the faceplate off of the front pulley wheel to access the governor washer.

Step 7

Pull the governor washer off of the pulley rod by hand.

Step 8

Put your variator system back together by reattaching the face plate, then the bolt, spacing washer and variator/starter mating piece, then the variator case lid, then the six case bolts, then intake case, then the intake case bolts and finally the kickstand.
