The convenience offered by automatic motorbikes to its users. Without having to manually shift gears, you can freely move your scooter and focus on driving. However, not a few consumers are disappointed with the performance of this CVT (continuous variable transmission) driven product. For example, some of the cases that happened to the Honda PCX, Honda Vario 150 and even the Honda ADV 150.
To note, CVT itself is a system consisting of several components. Aiming to continue the engine output to the rear wheels. Unfortunately, the translation process was not completely smooth. Most commonly there is a feeling of gredek in the area, especially during the initial pull.
This is apparently an impact due to the desire of producers to make their CVTs with minimal sound. However, it actually makes the area give off excess heat (overheat). So that it has an impact on the imperfection of the clutch lining biting the clutch housing.
Modification By Perforating The Clutch House
No need to worry because you can still work around this with light modifications. The first way is to perforate a certain part of the clutch housing to maximize cooling in the CVT. On the plus side, this method can also reduce the build-up of dirt from the clutch lining. It would be better if you go directly to a trusted repair shop.
Change Roller Weight With A Lighter One
In practice, the CVT roller also has an important role in smoothing the speed of power and torque to the wheels. As quoted from Wahana Honda, the roller is in charge of regulating the movement of the sliding primary sheave or double clutch housing. This component works with the principle of the centrifugal force, where it will move away from the rotating axis it surrounds.
Similar sources say, a touch of modification can be done by replacing a roller that has a lighter weight. Similar sources say, you can play or change the weight of the manufacturer's default roller which usually has a fairly heavy mass load.
"The use of such a roller will make the performance of your motorbike's CVT system much smoother when used for driving," wrote the material we quoted from the official website of Wahana Honda. This method can certainly be applied to the Vario 150, PCX and ADV 150 2021. For preference, it's best to do it with an experienced workshop and mechanic.
Replace a louder CVT
Another minor modification to improve the performance of the CVT is to replace the spring components that are already installed. Workshop mechanics usually recommend that you use a spring that is tougher and slightly longer than the motorbike's default. The goal is to speed up the acceleration process.
Modifications to the CVT section are commonplace for scooter owners
Availability per CVT can be found easily in repair shops or after market shops. Basically, you can adjust the usage of the spring according to your preferences. But it must also be adjusted to the specifications of the scooter that you owned earlier.
The method above can be a solution to overcome the symptoms of gredek or slippage that are usually found on automatic motors. In addition, you don't have to dig deeper into your pockets because the price is still quite affordable. Prices, especially rollers and per CVT, are still in the tens to hundreds of thousands.
Even though you have replaced it, it doesn't mean that you forget about periodic treatments. Wahana said that owners of automatic motorbikes are encouraged to pay attention to each component, so that risks such as damage can be avoided. Because once the damage is very complicated and takes time to repair it.
List of CVT components that must be cared for and check periodically
Rollers are often damaged due to negligence of the vehicle owner. This is usually due to the fact that scooters often travel long-distance routes. The condition of the roller, which was originally spherical, can turn into a bump if the motor is used to drive excessively and does not give it enough rest time.
Regular CVT scooter maintenance, mandatory!
If you are traveling long distances, ideally take a break every 2 hours. This is done to rest the engine following the CVT from overheating. In addition, it can also restore the body's condition after traveling. It should also be noted that the age or condition of the rollers also affects the way you ride. It is more likely that the shape will quickly change to sharp or imprecise if you often aggressively push the gas deeply.
Next is the v-belt. This special rubber component serves as a continuation of rotation from the engine to the rear wheels. The condition must be considered because it is prone to damage. Either it is a crack or it may not be flexible anymore. When we find these symptoms, we suggest replacing them with a new v-belt.
Not only to improve CVT performance, but also to eliminate damage to other components in the sector. The worst risk of not being checked diligently is breaking up. Yes, its function is similar to a chain on a manual motor. If the chain breaks, the motor cannot run even when the engine is running.
3. Clutch lining
Attention must also be paid to the clutch lining. Not because of its unique shape like drum brakes on manual transmission motorbikes. The clutch pad has a function as a successor to the rotation which originally came from the secondary axle to the wheels. Maintenance and routine checks are mandatory for this component.
Ideally, at 24,000 to 35,000 km there is already wear on the clutch lining. If you want a longer service life, also pay attention to the way you ride. Avoid opening the gas in followed by sudden braking or while pressing the rear brake lever. For that, avoid the habit of putting your finger on the brake lever.
Good luck and hopefully useful!
