Tips for carburetor adjustment:
To start you need to have the motorcycle idling for about 3 minutes for the engine to warm up.
Once the bike is warmed up, give it a full throttle for a few seconds and hold for about 5 seconds at maximum RPM without releasing the throttle.
Turn off the bike and proceed to remove the spark plug.
Depending on the color of the spark plug, we can determine what the engine needs.
If the spark plug color is like coffee with milk (Color) it means that the bike is dry, you have to increase the pilot jet about 5 or 10 points more.
If the spark plug is only brown, or it is greasy, you have to lower the pilot jet about 5 or 10 points less.
