Hi,
I have a SYM 125cc scooter ( model name is duke), and recently i noticed that the fuel consumption slightly increased.
I was used to around 71 mpg, and now i'm getting only around 60 mpg.
Checked the air filter and it was dirty so i replaced it, but no change with the fuel consumption.
Different spark plug, also didn't help.
I added a fuel threatment additive, still no change.
The valves are also at the correct gap.
I tried to readjust the air/fuel mixture screw, but no luck there.
same fuel consumption.
Now, my scooter have an high mileage on it (67,000 miles).
I'm sure there is a loss of compression, although i don't feel that it have less power.
Can it be just that?
Can it be dirt inside the carburetor?
Any ideas are welcome.
Thank you.
