Carburettor adjustment advice:

To start, you need to keep the motorcycle idling for about 3 minutes so it reaches temperature.
Once the motorcycle is warm, take the motorcycle and give it full throttle for a few seconds and hold it for about 5 seconds at maximum RPM without releasing the throttle, turn off the motorcycle using the key and proceed to remove the spark plug. Depending on the colour of the spark plug, you can determine its condition, for example:

• If the spark plug is a light coffee with milk colour, the motorcycle is running lean and you need to increase the main jet by about 5 or 10 points.
• If the spark plug is just coffee coloured, it is running rich, so you need to decrease the main jet by about 5 or 10 points.
