There are few things more disappointing than starting out on a motorcycle and realizing that your scooter suddenly slows down. The engine runs in a normal way, but slows down in an unexpected way, other than your frustration level increasing. Before deciding to change your scooter or worse, before going for help you can try to troubleshoot your motorcycle to see what the real problem is.
You should know that the causes of these problems are numerous, we find in particular:
- A clogged injector
- Lack of air flow
- A seized engine
In this article, we'll help you fix your slowing scooter:
Cause 1: The injector of your scooter is clogged
Your scooter tries to accelerate when you are going at high speed, but there is no combustion which causes a sudden slowdown. If you know it sparks properly and there is gasoline in the tank, but it has been idle for a while, the culprit is likely a clogged fuel injector.
You can also manually inspect your fuel injectors. If they appear dirty and clogged, it means they need to be cleaned or replaced.

There are ways to clean your fuel injectors, including using a solution specifically designed to clean them. But since fuel injectors are generally inexpensive, you might as well spend your money on buying new ones instead of buying a tool to clean them.

You can determine if your air flow is the cause by inspecting your air filter in the air box. You can temporarily remove your air box or pod filters (if you are not in a dusty environment) and try spinning your scooter again. If your scooter runs smoothly, you know your problem is airflow.

solution:
There are several ways to fix a seized engine, but unless you are absolutely sure what you are doing, I recommend that you take your scooter to a store to have it fixed, or at least find out the exact reason why it is. seized.
