How To Make A 50cc Scooter Faster? – Different Ways That Work
If you have a 50cc scooter, the first thing you might want to do with it is to make it run faster. 50cc scooters have restricted engines that limit their speed to only 30mph (48kph). If you wonder if it is possible to make a 50cc scooter faster, the answer is yes, although it may be or may not be a good idea.
Each state has different rules and regulations when it comes to using scooters. Mostly, you do not need a license to drive a scooter. However, it should not exceed the 30mph limit on a flat road for a scooter to be legal. If it runs more than 30mph, then you will need a motorcycle license to ride it. But assuming that you have a motorcycle license, follow the steps below to know how to make a 50cc scooter faster.
Making It Faster
Manufacturers restricted their scooters to only 30mph to meet the regulations, as mentioned earlier. You will need to derestrict it to make it faster and need to do two or three things. What are these restrictions?
- The CDI or the ignition module limits the scooter's engine rpm. Usually, a 50cc scooter might be restricted to 7000rpm.
- It does not allow the full range of gear ratios due to the Variator with an oversized boss that limits the maximum speed.
- The carburetor jet is relatively small to limit fuel flow (and meet emission regulations).
Considering these factors, here are the things that you can do to make your scooter faster:
- Replace the CDI or do some tweaking on the stock module. This will allow the engine to run at a higher rpm.
- Remove the oversized variation boss. Doing so will allow higher gear and give a little more top speed.
- Replacing the existing jet with a slightly lighter main jet will richen the mixture a bit. This will give the scooter a better performance but will use more fuel, though.
- Installing a set of variator rollers of the right weight is another simple and inexpensive way to improve your scooter's performance. You have to experiment, though, to know the right variator for you. Heavier rollers give a slightly higher speed but may take longer to get to the destination. On the other hand, the lighter may give you faster acceleration; however, the top speed could be slightly lower. The type of scooter and the rider's weight are some factors to consider in choosing the right set.
There are several ways to modify your scooter and improve its performance. Knowing how to make make a 50cc scooter faster will be a lot easier if you are familiar with the engine or a mechanic by heart. If you badly want to have a faster scooter, another idea is to upgrade your 50cc to 150cc scooter. That way, you can be sure that it is safe and legal, so you don't have to worry about penalties or fines when riding your scooter.
