1. Overcome Disease carburetor Vacuum, Rubber Hard and shoot!

Shoot common diseases vacuum carburetor

Carburetor vacuum has its own character. The most frequent diseases arise also different from regular carburetors. Any disease motorcycle carburetor on this now?

First, of rubber vacuum. The function of this rubber raised skepticism rose to open the venture orifice. Rubber can be raised skepticism because there is a vacuum at the top of the carburetor due to air flowing fast.

Have long been used as a result, the rubber will harden. Could be because of the heat engine or it could be due to frequent contact with splashes of petrol.

Rubber has the character not stand the heat. Nor is resistant chemicals kinds of gasoline. The result can be harsh. When it hardens, it will be hard to lift skepticism occurred despite a vacuum. This resulting venture orifice open so not all.

As a result of it, the supply of fuel gas is not optimal. Engine power does not go all out. "It makes the motor speed sometimes just stuck 40 km / h," said Yudi, mechanical PJM (struggle Motor) in Kebon Jeruk, West Jakarta.

If the vacuum is already hardened rubber, there is no cure. Because it can not be made pliable again. The solution had to replace the original. "Because if life is imitation sometimes less flexible while still new," commentator Yudi further.

However troublesome kinds of Yamaha Mio. Rubber vacuum sold a set with skepticism. "Because of skepticism and rubber made death alias can not be removed," says Yudi which is now becoming a big thank scuba or automatic servicing it.

Set not too much air (left). Hard rubber degrade the performance (right)

Between original and imitation, the price can be much difference. Could be four times that. So many are interested in using a rubber imitation although in the end behind again with the OEM (Original Equipment Manufacture).

Other diseases in the carburetor vacuum can be seen through the sound of an explosion from the exhaust. "Dar .. der .. bam ... when deceleration," said Yudi who handled many of these cases. These events usually when the brakes to reduce speed.

According to Yudi, the sound of explosions in the stomach exhaust occurs because of the wind in the carburetor settings. Usually the setup too much air. Finally drought and exploded in silencer.

Can occur one set for carburetor adjustment screw air in the vacuum that is set too dry or mostly air. To that must be made wet.

To cope with the sound of explosions from the carburetor vacuum, air screw settings must be made small. So that the wind is not most. How to set the carburetor similar to ordinary really.

2. Carburetors Conventional Surgery Reveals Part + function!

First, the motor population in the country is dominated by a conventional carburetor or called piston valve, nor the skepticism. "Working this model depends carburetor throttle openings do motorists," said Endro Sutarno of Technical Service Training Development PT Astra Honda Motor (AHM).

Thus, conventional atomizer tend to be more responsive. However, due to regulatory Euro 2, forcing the use of more fuel efficient and does not cause pollution. Cheap and easy way used carburetors CV (Constant Vacuum).

For that we need to know more different conventional carburetor and CV models. Not lagging behind, the performance of each part. There are at least seven body parts other than the function of vital support this carburetor works perfectly.

Butterfly

The term butterfly valve. Choke function when it is activated. These blades will close the venture so that the incoming air will be reduced.

So, that sucked fuel only and a bit of air. The mixture becomes richer. Or more gasoline. Finally, so much faster machine life.

Bottles + Jaruk Skep

Bottle or skepticism serves to open the venture. So that the greater the air required. Medium needle skepticism or so-called open discharge their duties needle jet fuel from the nozzle alias main-jet.

The more the lifting of the needle, the discharge of the fuel that goes into each venture. Needle skepticism typically have a setting clip. If the position of the clip further below, a fuel increasingly wasteful. Vice versa. The bottom of the needle also has settings.

TSS / TPS

Throttle Switch System (TSS) and there are also manufacturers who call position Throttle Sensor (TPS). TSS or TPS function to regulate the degree of suitable ignition and throttle engine rev.

Part of this has a button that connected the bottle skepticism. If the position of skepticism under conditions so ON. Central, OFF and On return if full aperture skepticism. Linkages of fuel efficiency. Similar injection.

Main Jet and Jet Pilot

Pilot-jet function for supplying fuel at low speed (stationary) up to 4,000 rpm. Supplies fade away and move on to the main-jet corresponding openings skepticism and finally replaced in full by the main-jet to round up.

The hole in the holder main-jet function adds air to fuel may be pushed quickly to the top. If the hole is raised, making the incoming air so more and more. Of course, to make the mixture so lean alias poor. Danger!

pilot Screw

Pilot screw duty increase or decrease the engine rpm. The more plays into the (right), the bolt will push the skepticism so that the air bottle opening.

Average water screw, working set air and fuel mixture is ideal. Each motor has different settings. But, usually 2 to 2.5 turns after shut-out. In connection with the pilot and main-jet.

float

Performance is supported needle buoy. The second part serves as the tap open and shut the flow of gasoline from the fuel tank. The needles themselves, as if like a valve. Because when gasoline in the carburetor bowl is full, then the needle will close the incoming flow of gasoline. In the bowl of the pipe there is also a duty to throw petrol filled in the bowl.

ACV

Some carburetor standard motors, available Air Cut off Valve (ACV). Honda Supra X 125. As part of this function eliminates the symptoms alias shot fire back when gas was closed spontaneously.

Because when the gas shut suddenly, the incoming air is still a lot. But, a little fuel. The mixture so poor and cause symptoms shooting. Part of this relates to pilot-jet.

 3. Functions Mouth Holes in karbu

Do not assume that any holes that exist in the mouth of the carburetor that baseball vital function. Therefore, the hole was related to the support of imperfect performance carburetor.

For example in carburetor Honda Supra X 125. In the carburetor venture duck 125 cc three holes. Pit the top left, associated with ACV (Air Cut Valve).

Hole central part, related to the pilot-jet and stationary. Medium biggest hole in the bottom, has a connection to the main-jet performance.

4. Carburetor Vs Conventional vacuum, Between Pull And Efficient

Vacuum carburetor technology a step further, so economical and environmentally friendly

Carburetor, the atomizer of fuel to the engine is already experiencing technological advances. After a long time loaded with a conventional carburetor, later motors that are marketed in Indonesia apply vacuum carburetor. Carburetors of this type has advantages over the conventional ones.

Slightly reviews first about Couse. Starting from the carburetor that we know first, conventional systems. Language in height, this carburetor called Venture Meter (VM). It works is simple. Volume or discharge of air and gas supply fuel directly regulated through the twisting motion of the gas. Torsion gas, piped wiring, attract direct bottles or piston skepticism skepticism.

In contrast to the carburetor is commonly called a vacuum. Mentions technique, CV (Constant Velocity or Constant Vacuum). Work karbu this model based on the vacuum in the combustion chamber. This fuel supplies ahead of the same level VM. CV, moving up and down a bottle of skepticism depends vacuum in the combustion chamber, or the air pressure between the inlet and the swan neck.

"So, in the carburetor vacuum, gas channeled torsion movements cable to the carburetor works just fishing. Therefore, the pull cord twisting or open gas valve butterfly. Aperture butterfly valve which regulates the level of vacuum in the combustion chamber, "said Cheppy Sugiarto, racing mechanic who now began to explore the vacuum carburetor settings for scooter racing team AHRS.

Cables from the sheath gas is associated with a butterfly valve mechanism

Then, how the bottle rising skepticism in vacuum carburetor? Well, here he explained. Because the emptiness of air in the combustion chamber is opened by the valve butterfly, it sucks air out. That sucked the rubber membrane that is above the carburetor. These membranes are connected bottles of skepticism in CV carburetor. Because the membrane is sucked, bottle skepticism drawn upward. So keen was the needle skepticism also connected with a bottle of skepticism.

The system creates a more regular supply of fuel according to the needs of the combustion chamber. Due to the vacuum level determines the engine speed high-low openings bottle skepticism. "So, more efficient vacuum carburettor. Because of skepticism and indirectly raised the needle so twisted sheath gas, "said Adriansyah, mechanical Adri Speed ​​in East Jakarta

After all, both Cheppy and Adriansyah, claimed CV carburetor models are less preferred for motorcycle enthusiasts with character pull cash. Why, yes it was. Although gas twisted, the motor would not immediately drove. the supply of gasoline is determined vacuum in the combustion chamber.

So, if we are using carburetor vacuum, gas betot direct useless. Because the carburetor will keep supplying fuel demand and the needs of the spin machine.

"So, instead of income. Because air is forced in as much as possible into the combustion chamber, the fuel discharge was little. The result was not optimal combustion and energy like a blank for a moment. The new force will be restocked on the time duration of approximately 1 second, "said Cheppy and Adriansyah.

So, do not be strange if the motor is wearing CV carburetor vacuum aka Bolot pull over. After all, this bike is more economical. Staying been, like speeding directly on a conventional carburetor. If you want to save money, so select the type of vacuum.

5. Carburetor Vacuum, Avoid Dust and Compressors

Sharp objects and rubber trigger compressor leak

Appropriate system works more stable gas supply of fuel, carburetor-type CV (Constant Velocity) powered vacuum rubber for the opening and closing piston skepticism. But proved far more sensitive compared to the type of PV (Piston Valve).

What cause? It is said that make fuel injection device, the piston motion skepticism baseball pulled the throttle, but from the opposite piston while sucking air and fuel. The greater the suction, rubber vacuum chamber in the lower to be able to lift the piston skepticism upwards.

For that reason, it is natural that the treatment on CV carburetor slightly different although the principle of equal treatment. Make sure the space inside the carburetor CV must be clean of dust and dirt that cause the crust. Soale, crust that triggers the slow motion of the piston skepticism even locked.

Do not remove the filter and replace the filter often new

So make it a habit to replace the air filter according to the procedure time replacement. "Always use the air filter and should not be removed, because the air outside is not necessarily clean of dust or particles in the crust cause piston skepticism," said Didier Rosidin, mechanical Castrol Bike Point Oryx Motor in soreang.

In addition to diligent replace the air filter, rubber vacuum in the head CV carburetor try not often tampered with if it does not have to be removed. Moreover, the rubber diaphragm especially vulnerable sharps high pressure air.

If baseball is a problem with the vacuum, vacuum rubber advisable not often removed let alone washed wear rubber causes fluid so stiff. "Do not also get used rubber vacuum or hole venturinya cleaned using pressurized air support or air compressor. Even feared it would damage or even tearing the rubber vacuum, "said Eksa Syahputra alias Medi Speed ​​mechanics at Jl. Harsono RM, Ragunan, South Jakarta.

And that should be a concern is for the motor mounts that have been adopted or CV carburetor, though more durable components are encouraged to familiarize use unleaded fuel (non-lead).

That's because the leads are joined sucked baseball will accumulate in the body piston skepticism. As a result, the motion skepticism so more slowly.

6. Rubber Vacuum Carburetor Thick Nah easily stretched

Various rubber vacuum carburetor

Carburetor vacuum rely rubber material to raise skepticism. However, because it is made of rubber, even faster contact allergy gasoline. "So, because of the nature of the rubber that easily stretched if exposed to oil, we need to choose the material more robust," said Andy Mulki of Light Metals Motors (CLM) in Bates Kreo, ciledug.

According to Ko An, greeting familiar, if rubber vacuum is already stretched, may present many problems. "It usually starts with insomnia regulate the motor idling. Because rubber was baseball ngeplak position again where it should be, "said the man who once studied to the late Om alias Michael Chia Iskandar.

It also proves that the condition of the rubber carburetor vacuum system has the influence or big role. Karenanya, suggested when the motorcycle maintenance to disassemble or clean the carburetor, need to check the condition of the rubber. Make sure if it is hard, stretchy or even may already be torn. If you have this, it's time to replace.

How could examine it with palpable. "If it is stretchy could have felt, it could be with a little tugged. But do not tear, "An Ko message again.

Further! Based on the experience so far, Ko An many find rubber vacuum interchangeable. That can wear exchange. Of the same brand, or not a problem is also taken from other brands.

Sure to be seen beforehand as well. Is the measure sought already appropriate. Auk ah muddy? Here are some types that can be mutually substituted.

Honda

Honda rubber vacuum at all. Motor is already using a carburetor with a system like this, kayaking BEAT, Vario and Scoopy. "If Honda was yes all the same, nothing different. So, if there is damage or having to replace an earlier scuba, may each wear, "the story of his gray mechanic who already dominate the hair on his head.

"It is said that there are also selling the said rubber made in Thailand. But I think it's all the same quality, "added the man was friendly. For the price, rubber vacuum usual for Honda in the range of USD 20 thousand.

Occasionally need to check the condition

Yamaha

Yamaha Mio can not buy a vacuum rubber wrote. Should skepticism all along. But, for Nouvo even can. "Well, for this Yamaha there is little difference in the two scuba it, Nouvo can buy rubber alone," he added.

If you have to replace, then create Nouvo rubber had been able to use a Suzuki Satria F-150. "In terms of quality rubber FU was the same as had Nouvo. Only if all spare-parts store, has Nouvo no, can also buy have FU, "the message for the owners Nouvo.

Suzuki

Create Suzuki, highly recommended by Ko An to select or use a Suzuki FXR. "Because rubber vacuum thick and strong, so it is definitely more durable," said Ko An.

But, it has FXR is no weakness. at about the price that is much more expensive. "Last check prices, sold more than Rp 150 thousand, while the standard Spin only Rp 30 thousand," he said.

Indeed Spin, Sky wave, SkyDrive Hay ate even recommended to use these mechanics have FXR. Even Thunder 125 can too!

7. Vacuum Cleaning Rubber carburetor Just Wear Wipes

Disposable wipes not let Teflon coating is damaged

Carburetor used in the motor current, average wear vacuum carburetor. Her work systems rely on vacuum air space to push the fuel.

Maintenance carburetor vacuum is actually not much different from a conventional carburetor. Which makes little difference in the vacuum carburetor fitted rubber material is thin and flexible.

The function of this rubber seal off a gap so that the vacuum maintained skepticism, skepticism moving the suction air can be more smoothly. But if the hard vacuum or shredded rubber, skepticism would definitely disturbed. If the motor-started will be difficult.

For that there is special treatment while the carburetor vacuum cleaned so as not to damage the rubber. Before the body carburetor cleaned, formerly dislodged rubber vacuum. Of course that is not exposed to splashing rubber vacuum cleaner that contains chemicals. The rubber should not be exposed to the fluid either gasoline or chemicals.

Easy to take off the rubber. Just open the screw lid. Then pull per skepticism and grab the rubber. Then lift. After the rubber vacuum off, the body of the carburetor can be cleaned like conventional carburetor cleaning.

Ie spraying cleaner use in all parts of the nozzle. The goal is removing sediment fuel attached to the wall. Next, set aside some time. After falling dirt, wipe with a cloth until clean.

"If the crust is clean, soak the body used gasoline or diesel fuel," said Tono P. chief mechanic PT World Motorindo Fantastic, authorized Honda dealer in Jl. Kebayoran Lama No. 556, South Jakarta. The goal is that the dirt is still stuck on the metal net.

Then for rubber vacuum, does baseball need to be cleaned. "Rubber vacuum true dirty baseball. Not cleaned also not a problem, "said Tono.

Carburetor body may in spray

If you still want cleaned, use a dry tissue. In addition to the rubber material is thin and pliable, in this section there is a layer of Teflon. This layer serves to protect the rubber layer from being scratched.

"Please wipe dry disposable wipes. Baseball needs to be suppressed because of dirt on the rubber a little, and not a crust, "commentator Tono.

Also check the rubber resiliency of the vacuum. Because if already hardened, certainly will greatly affect engine performance. Can certainly be fixed engine speed of 40 km / h.

That's because the hard rubber hard sucked by a vacuum. Consequently ascent skepticism late and will not be lifted fully.

8. Membrane Vacuum Carburetor Problems, Round Machine Suspended!

Stuck only 40 km / h

Alias ​​rubber membrane in a vacuum carburetor most important part. Because of the importance the manufacturer suggested that baseball is open. But, there are still curious opening of the membrane.

After opening the rubber carburetor, no actual treatment baseball allowed. Taxable gasoline that can make the structure of the membrane material change or contact tiban one tool-kit that could have been a hole.

"What's great not to be dismantled if baseball is no problem. Suppose there is a problem, it can be perceived first time the motor is used, "said Slamet, Instructor Yamaha Technical Academy (YTA) of PT Yamaha Motor Indonesia, Jakarta.

Damage rubber vacuum can affect the mechanism of action of the carburetor. In air or O2 membrane encourage and increase skepticism or skepticism alias piston carburetor. There was a slight problem just climbed down-skepticism will be felt when the motor is rotated gas.

Problem for the rubber component fuel atomizer can vacuum air is likely to occur. Probably already perforated rubber though only a speck, one position pairs, wear imitation membrane, until a genuine skepticism is not too hard or soft.

There are symptoms that feel the time is wearing the carburetor mounts vacuum conditions slightly hollow membrane. Motor speed can not get full.

Rubber plug correct position. Stand entrance to the gutter (right). rubber one pair (right)

"Round like muffled engine. The maximum speed is only up to 40 km / h, "Sarwono ambushed Edhi, In structure Technical Training Department of PT Astra Honda Motor (AHM), Jakarta.

Speck holes in the carburetor rubber vacuum there will be leakage that can rapidly make piston baseball. In fact, the piston may only move up 20%.

The reason, the incoming air into the vacuum chamber rubber moving out again because there is a hole. Air out what makes baseball a perfect vacuum. Finally, baseball piston can be lifted.

Other problems also exist when mounting the rubber membrane vacuum carburetor. After playing one off the membrane vacuum installation. Most often the position of the holder rubber baseball snugly in place.

Signs installed perfectly membrane holder see section protruding rubber. Protruding parts placed on got a rubber mounted in the carburetor.

"Mean average baseball position. Skep rising skewed because of the rubber stuck. The effect can not be full speed, "Slamet definitely based in Cempaka Putih, Central Jakarta.

9. Install Intake Manifold Variations? Beware of shape!

The new dressing intake manifold variations, why suddenly so wasteful gasoline huh? Then on the surface there seemed grain moisture intake. Whereas before baseball so, you know?

From the search results, detected intake manifold holes are smaller than the hole carburetor. As a result, fuel gas stream of hit the wall more into the intake. So there is gas fuel back out to muzzle carburetor.

"In addition to fuel consumption. Also because the fuel gas knock, causing the surface of the intake dewy. "So before purchasing or want to replace the intake manifold product variations, always pay attention to the size of the hole," remembers Merit, Tuner team Kept Yamaha TOP 1 FDR Indoparts KYT from Yogyakarta.

Ideally, the circumference of the venture carburetor manifold holes have the same size. If the carburetor diameter of 22 mm, which means goose neck holes are the same. In order fuel gas to the kitchen runway smoothly without a hitch.
