Carburetor adjustment tip:

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

• If the spark plug is a light coffee with milk color, the bike is running lean; you need to increase the main jet by about 5 or 10 points.
• And if the spark plug is only brown, it's running rich, so you need to lower the main jet by about 5 or 10 points.
