USAPANG BOLA/FLY BALL DISKARTE AT MGA BAGAY NA DAPAT MALAMAN. (YAMAHA MIO SPORTY)

Summary

In this vlog, the host takes viewers through a detailed exploration of flyballs in the Mio Sporty and Mio Sport motorcycles, focusing on the CVT system and its components. The discussion covers the importance of flyball weight in adjusting acceleration and top speed, as well as how modifications, like changing flyballs and upgrading the pulley system, impact the bike's performance. Practical tips on balancing the CVT parts, the role of the crankcase, and the impact of flyball weight are shared based on personal experience. The video also emphasizes that while racing parts can improve acceleration, they don't increase engine capacity.

Takeaways

• 😀 Flyballs play a critical role in the Mio Sporty's CVT system, affecting the performance by adjusting the pulley and belt assembly as the engine revs.
• 😀 Lighter flyballs (e.g., 8g) improve acceleration, while heavier flyballs (e.g., 10g) enhance top speed but reduce initial responsiveness.
• 😀 Flyball weight adjustments do not change the engine's displacement or horsepower, meaning the engine's performance remains based on its stock rating (e.g., 115cc).
• 😀 Mixing different flyball weights (e.g., 8g and 10g) can offer a balanced improvement in both acceleration and top speed, catering to various riding preferences.
• 😀 Regular maintenance is important, as worn-out parts like the back plate and sliders can cause noise and affect CVT performance.
• 😀 A stock CVT setup offers balanced acceleration, mid-range, and top speed, but modifying the flyballs can adjust the performance profile to favor either acceleration or top speed.
• 😀 Flyball adjustments should be aligned with the load and weight of the rider, as a lighter rider will experience faster acceleration compared to a heavier one.
• 😀 The CVT system operates like a transmission, so upgrading the flyball or other parts won't increase engine displacement, just improve how the transmission handles power.
• 😀 When tuning the Mio Sporty, it's crucial to understand the relationship between flyball weight and engine load; higher load setups (e.g., 125cc or 130cc) require corresponding CVT adjustments.
• 😀 Switching to racing CVT parts does not necessarily mean a faster engine; the real benefit is smoother acceleration and better handling of power, especially for city riding.

Q & A

What is the purpose of the flyball in the Mio Sporty's CVT system?

The flyball in the CVT system helps adjust the torque and shifting of the scooter. It influences the acceleration and top speed by moving the belt and pulley components when the engine runs at high speeds.

How does the weight of the flyball affect the Mio Sporty's performance?

A lighter flyball (8 grams) improves acceleration but reduces top speed, while a heavier flyball (10 grams) provides stronger top speed but slower acceleration. The weight balance affects how quickly the pulley assembly responds during shifts.

What is the role of the pulley in the CVT system?

The pulley works together with the flyball to adjust the belt position. When the flyball moves, it helps the pulley shift the belt to optimize torque, thus influencing the scooter's acceleration and speed.

Why is it important to balance the flyball's weight with the engine displacement?

Balancing the flyball's weight with the engine displacement ensures that the CVT system performs efficiently. Using a weight that matches the engine's capacity allows for smoother power delivery and avoids overloading the system.

What happens when the flyball is not properly balanced in the CVT system?

If the flyball is not balanced properly, it can cause the scooter's CVT to underperform. This could lead to poor acceleration, reduced top speed, or inefficient power delivery, which can strain the engine and other components.

What tools are required to remove and adjust the crankcase cover and pulley components?

To remove the crankcase cover and adjust the pulley components, you'll need a 17mm socket, ratchet, and optionally a Y tool to counter the pulley. Alternatively, you can use a socket or screw from the crankcase to counter the pulley without a Y tool.

What causes the noise in the Mio Sporty's CVT system?

The noise in the CVT system can be caused by loose or worn-out components such as the slider and back plate. These plastic parts can become worn over time, leading to increased friction and noise during operation.

How does changing the flyball weight affect fuel consumption?

Changing the flyball weight can affect fuel consumption by influencing the scooter's acceleration. A lighter flyball improves acceleration, reducing the amount of throttle required to reach higher speeds, potentially leading to better fuel efficiency, especially in city driving.

Why do some people mix flyball weights in their CVT setup?

Some riders mix flyball weights (e.g., using three 8-gram balls and three 10-gram balls) to balance both acceleration and top speed. This setup allows for a quicker take-off while still maintaining a reasonable top speed.

What is the ideal flyball weight for a stock Mio Sporty engine?

For a stock Mio Sporty engine, the recommended flyball weight is 10 grams. However, depending on the rider's preference for acceleration versus top speed, an 8-gram flyball may be used for better acceleration.
