Title: Engine loosing power with "2 dots" of Fuel
Post by: williansoler on October 02, 2024, 06:26:55 PM
Hello guys,

I have my GT 300I for two years and 16000KM on it. Never had any issue. Do my maintenance always before time/KM. Recently I've been experiencing some loss of power when the fuel mark went near 2 dots of fuel remaining. Yesterday I had this problem and thought it was bad quality fuel as the problem went away as soon as I filled up the tank. Today I did a 100KM trip with no issues and, as soon as I got the same point as yesterday (2 dots of fuel remaining), the scooter started to loose power and I had to be very cautios with the throttle to make it to the fuel station. It's like, it goes little bit better on leveled ground but as soon as I throttle up or have to go uphill, it starts to loose power at the point that I have to stop completely. As soon as I filled up the tank it went away again.

Before I filled up the tank, I visually checked for remaining fuel on the tank and there were more than enough fuel.

Never had this issue before, I have driven some times to the 1 dot fuel mark and never had this loss of power issue.

Does someone already had this issue? The Kymco repair shop told me that It might be a fuel pump issue but it's strange that it only happens at an especific fuel quantity.

Thank you very much!

Kind regards,

Willian

The only time I experienced this was with my X-Town 300i and it was a vacuum forming in the fuel tank which cured itself when releasing the fuel filler cap. 

When you stopped and checked for fuel, was it OK afterwards?

Neils hint might be done first, open filler cap.

Sounds to me like inline fuel filter/pump (fueltank) related issue.
Take the fuelpump out, change the filter and see if the prob is still there.
If still there, change the pump-body AND the fuel pump relay.

Maybe att link helps

This is a fairly common small motorcycle issue.  I always solve it by checking/cleaning the fuel tank vent, air filter, and the carburetor.  It's one of these.  If it's fuel injected, skip the carb part, but have a look at the fuel pump!
