Takeaways

• 😀 The Honda Supra is a robust motorcycle with specific sounds to watch out for, such as 'cik cik cik' and 'tek tek tek'.
• 😀 Sounds from the left, right, or front of the motorcycle should be checked for abnormalities, as they may indicate issues.
• 😀 A stable 'tek-tek' sound across a wide RPM range can indicate problems with the valve adjustment (klep setelan).
• 😀 If the motor's sound becomes harsher, it could be caused by a dirty tensioner, which may need cleaning.
• 😀 Tensioners that appear blackened but still drip oil are usually fine, but caution is necessary.
• 😀 Dirty or dry parts in the carburetor can affect the bike's performance, and this should be checked for cleanliness and oil level.
• 😀 When the oil doesn't stick to the components properly, it may indicate a need for an oil change and maintenance check.
• 😀 Using oil that's thicker than usual can help improve engine performance, especially for long-distance rides.
• 😀 The motorcycle should be regularly maintained, including ensuring that the spark plugs and oil are in good condition.
• 😀 Any abnormal noise or vibrations, particularly at higher RPMs or during acceleration, should be addressed immediately to prevent long-term damage.

Q & A

What could be the cause of a 'cik cik' or 'tek tek' sound from the motorbike?

The 'cik cik' or 'tek tek' sounds are usually caused by the valve setting (setelan klep) or the tensioner. If the sound is stable at both low and high RPMs, it likely originates from the valve clearance.

How can you fix the 'tek tek' sound caused by the tensioner?

The tensioner can be cleaned by disassembling and washing it. After cleaning, lubricate it and reassemble it. This will help reduce the unwanted sounds.

What should be done if the motorbike has a dirty or worn-out tensioner?

If the tensioner is dirty or worn out, it should be cleaned thoroughly. If it shows signs of wear, consider replacing it to ensure the bike's engine operates smoothly.

Why is it important to maintain the oil level and quality in the motorbike?

Maintaining the oil level and using good-quality oil is crucial for the engine’s longevity. Low oil levels or poor-quality oil can cause engine parts to wear out prematurely, which can lead to costly repairs.

What should be done when the oil level falls below half?

When the oil level falls below half, it’s essential to replace the oil. This ensures the engine is properly lubricated and functioning optimally.

How can you determine if the spark plug is causing an issue?

If the spark plug has dirt or excessive buildup, or if the bike experiences starting problems or irregular idling, it may need to be cleaned or replaced.

What type of spark plug is recommended for better engine performance?

It is recommended to use a spark plug with a colder temperature rating, which can help in maintaining a stable engine performance, especially during long rides or in higher temperatures.

What should be checked if there is a knocking or ticking sound from the engine?

If there is a knocking or ticking sound, it could be caused by worn-out or poorly lubricated components like the tensioner, valve clearance, or the clutch assembly. It is important to inspect these parts and ensure they are in good condition.

How can you tell if the engine’s camshaft is starting to wear out?

A camshaft that is wearing out might produce a ticking or knocking sound, especially when revving the engine. The noise may become more noticeable at higher RPMs.

What is the effect of using a thicker oil in the engine?

Using thicker oil can help reduce engine noise and improve lubrication, especially if the engine has started showing signs of wear. Thicker oil can help maintain engine pressure and protect moving parts.
