Negative pressure carburetor essentials
Carburetor's Restore is being done.
Except for Body, I was thinking of replacing almost all of them.
This is the replacement of the rubber part called Diaphragm.
Because After Fire has been appearing frequently in spite of Carburetor setting of Pilot system.
ESTRELLA will be Carburetor negative pressure type.
Carburetor negative pressure type
The system lifts using the negative pressure of air passing through the carburetor by means of a valve called a diaphragm.
This one does not have Cableetc. on the Piston Valve itself, and Axel opens and closes the Throttle valve.
When the throttle valve opens, the passage between the engine and the air cleaner widens and more air flows. The negative pressure of the air at that time sucks up the Piston Valve by the Diaphragm, and as a result, the Gasoline is sucked up and becomes fog.
[How the Carburetor negative pressure system works.
○AxelWire is connected to the Butterfly valve ○When the Butterfly valve opens, the intake increases, but the Slide valve behind it is not linked to the Butterfly valve, and the Slide valve opens at a speed controlled by the weight and Spring.
Throttle response is gentle.
[*Diaphragm].
...Diaphragm is Material:Rubber membrane (Diaphragm). The membrane expands and contracts due to pressure fluctuations inside the carburetor, sucking up fuel like a pump. 。
procedure (see Figure 2).
The negative pressure generated by the ups and downs of the engine piston lowers the pressure inside the carburetor. 。 The Diaphragm is extended following the lowered pressure.
[Malfunction due to deterioration or tearing of the diaphragm].
If the diaphragm is torn or deteriorated, even if the air in the throttle valve is sucked out from the suction port, the air in the venturi is sucked in through the crack, so the valve does not have negative pressure and the piston will not rise. 。
Also, as the diaphragm hardens, it becomes resistant to piston rise.
The Piston in the→carburetor will not move or will be difficult to move, making it difficult for fuel to be supplied.
→Engine not following the rise.
Symptoms
BackFire (After Fire) occurs.
I can't get going no matter how many times I open Throttle.
How to exchange
(1) Turn off Fuel Cock.
↓
(2) Remove the Fuel Hose on the carburetor side.
↓
(3) Remove the bolt that is connected to the carburetor on the Engine side.
↓
(4) Remove the thailand portion of the Accelerator Wire attached to the carburetor and separate the wire from the carburetor body.
↓
(5) Disassemble Carburetor.
There are many small parts, so don't lose them.
*Collect them in Tray, etc. ◎
↓
(6) There is a diaphragm in the upper part of the carburetor body.
There were no tears or holes, but the rubber part seemed to be hardened due to deterioration.
↓
(7) Reassemble the Carburetor as it was and assemble in the order of (4) →? to make Large sturdy.
after replacement
◎After Fire at the time of embellishment is gone.
Throttle response is not sharp, but it seems to follow the accelerator operation.
The negative-pressure Carburetor does not offer any notable acceleration, but it can be used in a variety of weather conditions.:Pair (for Left and Right) If you fix them properly when they are out of shape, you can keep them with you for a long time.

Check with Carburetor Vehicles if it is old.
ESTRELLA's Restore is still going on (laughs).
I'm not seeing any glitches at this point, but I'm concerned that there may be some in the near future.
I've been thinking about it a lot again.
The area around the Fuel Cock is dirty, i.e., I saw seepage of Gasoline, so I replaced it. 。
It may be due to the deterioration of internal packing or something, but we decided it would be wise to replace it. 。
Fuel Cock (Negative Pressure Cook)
...Motorcycle Negative Pressure Cook refers to a Fuel Cock that uses air pressure (negative pressure). 。 Motorcycles have Parts called Fuel Cock that connect the Fuel Tank (Fuel Tank) to the Carburetor (Fuel Cock).
Where's Cook on this thing?
The parts called "Fuel Cock" are attached to the bottom of the fuel tank.
Applicable to vehicles with *ESTRELLA or Reserve (reserve fuel) Tank. Mainly Carburetor vehicles.
How Fuel Cock works.
‥ Negative pressure type Fuel Cock is generated when air (properly mixed with Gasoline) is sucked in when the Engine is running. "Negative pressure" The valves are opened and Gasoline flows through them by
Simply put, Gasoline flows when the Engine is running, and when the Engine stops, Gasoline flow stops.
[If the Fuel Cock malfunctions...
. Fuel supply will not be normal, causing Engine malfunction or fuel leakage.
→Idling unstable, frequent stalls, Gasoline smell.
Why is the Fuel Cock broken?
Cause
Rust in Fuel Tank, Gasoline mixed with rust passes through Cook →Damaged parts in Cook 。
Internal packing damage due to age-related deterioration.
*Packing is mainly Material:Deterioration occurs due to constant contact with Rubber and Gasoline.
→ Here's my case.
A simple image would be a water faucet, which is leaking even though it is supposed to be shut off properly, right?
This is similarly true for the Material inside:It's because RubberPacking is deteriorating.
Replacing the cook itself is not difficult, but there is a lot of work involved.
How to Replace Motorcycle Fuel Cock ~ESTRELLA~.
(1) Empty the fuel tank (Gasoline). 。
If you see Rust in the tank, remove the rust. Soak the tank in rust remover (Sun Pole can be substituted) and leave it to soak overnight.
↓
Turn the Fuel Cock to OFF.
↓
Pull out the Fuel Hose and the Negative Pressure Hose.
↓
(4) Remove the Motorcycle Seat and Side cover.
It can be done even if * attached, but if it is a Side cover with Gasoline, there is a risk of the paint peeling off or the Seat deteriorating.
↓
(5) Remove the bolt securing the tank and lower the tank.
↓
?Replace the Fuel CockAssy.
↓
? ?→? Return in this order to complete the process.
If you want to keep the cost as low as possible, you can replace only the packing with a large sturdy one, but if it is an old car body, it is better to replace it with a new one.
OEM is recommended over external if possible. Due to durability issues.

[How is it used?
Period:September 12, 2021 to September 7, 2023 to date
Distance:68,197 - 61,349 = 6,848 km
Was the one you received as per Image?
The image is exactly as it looked on the ZX10RR that I saw at Kawasaki Plaza.
Was the installation difficult?
Access is easy as the product is attached to a tank.
Easy to degrease with Parts Cleaner
・Quantity:Pair (for Left and Right) If you want to put it in the center to avoid asymmetry, you may want to change the Large size.
Since it is harder than a common tank pad (https://www.webike.net/sd/23719657/etc.), I was worried that it might come off against the curved surface of the tank, but the double-sided tape is strong and has not come off yet.
How was your experience with it?
Unlike a typical tank pad, it is a hard resin-like product that is quite slippery when traced with a finger.
There seems to be no worry about yellowing of the non-slippery transparent part, which occurs with common products.
It is about 2 years old and has not been used that much, but still no discoloration or deformation.
When running the Tandem, the One Shoulder Bag is hung on the front of the body, so the tank and pad are likely to be subject to rubbing, but there are no scratches etc. yet, perhaps because it is a material with a wide defensive range that is slippery, for better or for worse.
No products are ever "Glamour." I thought it might not fit in with the glossy Cowl, but it wasn't a Type that bothered me that much, so I don't mind. But I don't mind because it's not a type that bothers me that much.
[Included Parts:were they on?
Double-sided tape was stuck on the back side.
[Was there anything that disappointed you?
No particulars. It has a wide defensive range, high defense, and strength that does not come off.
[Similar looking products with different prices exist.
KawasakiOEM Parts with the same look and feel. 99994-1075:https://www.webike.net/sd/23654851/" and there are differences in price, but details are not available.
Although it is an OEM Product, it does not contain any maker logo and is a very solid product among Tank Pad. It has a wide range of protection and the price is about the same compared to other tank pads, so I think it is a good choice.
