Epekto ng MATIGAS at MALAMBOT na Center Spring sa Magaan at Mabigat na Bola | Moto Arch

Summary

This video discusses the impact of soft and hard center springs on motorcycle performance, specifically in relation to acceleration, top speed, and fuel consumption. The center spring, a critical component of the CVT system, influences how RPM is transferred from the belt to the clutch lining. Through practical tests comparing stock (soft) and upgraded (hard) springs with different weights of rollers, the video reveals how these variations affect acceleration times, maximum speeds, and fuel efficiency. Viewers are encouraged to consider their performance objectives when deciding whether to modify their center springs.

Takeaways

• 😀 The center spring is a crucial component of the CVT, responsible for transferring RPM from the belt to the clutch lining.
• 🚀 A soft center spring (800 RPM) provides better fuel efficiency but may reduce acceleration performance.
• ⚙️ A hard center spring (1,200 RPM) enhances initial acceleration due to increased pressure on the torque drive but results in higher fuel consumption.
• ⏱️ Acceleration tests showed that the soft center spring with a heavy ball achieved 0-60 kph in 7.3 seconds.
• 🏎️ The top speed with the soft center spring and heavy ball was recorded at 106 kph.
• ⛽ Fuel consumption was measured at 46.7 km/L using the soft center spring with a heavy ball configuration.
• 📉 Using a soft center spring with a light ball resulted in a drop in fuel consumption to 43 km/L but improved acceleration.
• 🔄 The hard center spring paired with a heavy ball provided better acceleration but had a fuel consumption rate of 36.8 km/L.
• 🔊 Pairing a hard center spring with a light ball led to a top speed of 104 kph but significantly increased fuel consumption to 34.9 km/L.
• 🔍 The optimal setup for balancing performance and fuel efficiency is a soft center spring with a heavy ball.

Q & A

What is the primary function of the center spring in a motorcycle's CVT?

The center spring holds the belt in place and transfers RPM from the belt to the clutch lining.

How does the weight of the roller balls affect the performance of the CVT?

The weight of the roller balls impacts how quickly the belt climbs the pulley, affecting acceleration and the overall performance of the motorcycle.

What are the two types of center springs compared in the video?

The video compares the stock center spring (800 RPM) and a harder center spring (1,200 RPM).

What were the fuel consumption results when using the stock center spring and heavier roller balls?

Using the stock center spring with heavier roller balls resulted in a fuel consumption of 46.7 km/L.

What effect does using a hard center spring have on acceleration and fuel consumption?

A hard center spring improves acceleration but typically increases fuel consumption compared to a softer spring.

What was the recorded top speed using the soft center spring and heavy balls?

The top speed recorded with the stock setup was 106 kph.

How did the performance change when a lighter ball was used with the stock center spring?

Using a lighter ball with the stock center spring provided better acceleration but slightly reduced fuel efficiency, resulting in 43 km/L.

What noise issues were encountered with the hard center spring and lighter balls?

Using a hard center spring with lighter balls led to a noisy operation, indicating stress on the CVT system.

What is the recommended setup for riders who prioritize fuel efficiency?

Riders who prioritize fuel efficiency should maintain the stock soft center spring and avoid using a hard spring.

What overall conclusion does the video reach about modifying center springs?

The conclusion is that modifications depend on the rider's goals: for better acceleration, a harder spring can be beneficial, but it generally results in higher fuel consumption.
