In most countries the law specifies that the speed of a moped should not exceed 35 mph or less. However, some of the mopeds are capable of higher speeds because of the components which are used. To comply with the law, the moped manufacturer may install components to restrict the speed. Many moped users would like to find out How to make a moped faster, and some tips are provided below for reference. The items required for making these changes are a wire cutter, screwdriver, impact wrench, saws-all, and metal file. Most vehicle owners already have these items in their toolkit.
Step 1
The first step in boosting the speed involves removing the baffle or air filter from the baffle box. The buyer can either purchase a performance muffler and replace the original muffler in the moped or modifying the muffler by installing an expansion chamber. For this the restrictors and exhaust pipe in the muffler will have to be removed, or holes have to be drilled. The bolts inside may require grinding. The narrow pipe and small pipe in the muffler should also be removed. After the narrow pipe is cut, the opening which remains on the exhaust should be crimped to close it.
Step 2
The next step involves check the transmission of the moped to ensure that it has the right amount of fluid as specified in the user manual. Dirty fluid or excessive fluid can affect the moped’s performance. Change both the oil filter and the oil, and only synthetic oil of highest quality should be used. The next important step involves removing the cover of the transmission assembly, so that the nut which keeps the variator assembly in place can also be removed. The variator assembly can then be removed. This assembly has pulleys with two halves, and a restrictor washer in between. After removing this washer, the variator assembly should be replaced in its original position and fixed with a nut.
Step 3
In the final step, the carburetor should be removed, the top taken off, so that the main jet of the carburetor can be replaced with a jet of larger capacity. While removing and fixing it is important to keep track of the screws used, and fix all the gas lines properly, so that there is no leakage.
Moped owners should be aware that if the speed of the moped is increased, it may have to be registered as a motorcycle. Exceeding the speed limit can cause collisions, fines, loss of license, confiscation of the vehicle. Moped modifications can adversely affect the life of the engine, and removing the baffle, may increase noise levels.
