The front wheel brake is controlled by the right hand and it is important to check its free travel. The free stroke determines the distance between the start of the handlebar and the beginning of the brake. If the stroke is too small, it hinders the separation of the front brake shoe and the front wheel brake drum, leading to a decrease in driving speed. On the other hand, if the stroke is too large, it negatively impacts the braking efficiency and hinders timely braking.
Before operating the rear wheel brake, it is essential to check the free travel of the brake pedal. The brake pedal, which is controlled by the foot, is responsible for activating the rear wheel brake. Therefore, ensuring that there is adequate free travel on the brake pedal is crucial for proper functioning and control of the brake. By examining the free travel, one can determine if there is any excessive looseness or resistance in the pedal movement, which may indicate a malfunction or need for adjustment.
The left hand usually operates the clutch, and it is important to check its free travel when making adjustments. It is crucial to ensure that the clutch is functioning properly to ensure smooth driving.
(4) Rear shock absorber.
When it comes to adjusting the rear transmission of a motorcycle, the key factor is the tightness of the transmission chain or belt. To check the tightness, locate the inspection point in the middle position between the front and rear sprockets or pulleys. Use your fingers to feel the movement of the chain and verify the distance of up-and-down movement, which will differ depending on the type of motorcycle. For smaller ones, it's generally between 10-20 mm, while for regular motorcycles it's between 20-30 mm. If it's a V-belt, press down on it with your hand using a force of 49N (or 5kg). If the belt sags by 10-20mm, it's at the right level of tightness. Remember to perform these checks regularly to keep your motorcycle running smoothly.
The carburetor idle speed is the minimum stable speed at which the engine can idle continuously with the throttle handle in the minimum position. To adjust the idle speed, start the engine and gradually turn the throttle handle while checking the free stroke, which should be set at 2 to 6 mm. If the rotation is less than 2 mm and the engine speed increases, the free stroke is too small. On the other hand, if the stroke exceeds 6 mm and there is no increase in engine speed, it means that the free stroke is too large. Make sure to adjust the idle speed properly to ensure smooth engine operation.
