How to Take a Governor Off a Moped

Manufacturers restrict mopeds using various methods.

Manufacturers often restrict modern-day mopeds with a governing device due to recent government laws concerning these vehicles. Often, brand-new bikes will have a top speed of only 30 mph. If you are looking for more power out of your bike, whether in acceleration or top speed, you can upgrade your moped's engine to make it perform at its maximum capacity. Fortunately, this process only requires a few household tools and about an hour of your time.

Things You'll Need

• Phillips screwdriver
• Replacement carburetor jets
• Aftermarket muffler

Instructions

1. Remove the air filter/box. Your moped has an air box that restricts the amount of air flow going into the engine; removing this box will allow as much air as possible to go into the engine, resulting in better fuel performance and a faster top speed. The air box is located by the carburetor, usually held on by two screws; remove them with a screwdriver.

2. Remove the restrictive carburetor jet in the carburetor. Remove the carb, and strip it down to its bare-bones metal. When taking your carburetor apart, remember where everything goes so you can put it back together properly. Locate the gold screw with a hole in the head. This is the carburetor's jet, which restricts the amount of fuel going into the engine. Replace this with a larger jet, and put the carb back together.

3. Replace the stock muffler with an aftermarket one. Although this process can become tedious and difficult, a new muffler can increase both top speed and acceleration. When replacing the muffler, follow the instructions carefully to ensure a successful installation.

Tips & Warnings

• You can purchase a big-bore kit that will increase the size of your carburetor; it can often increase your moped's speed by 15 mph or more.
