If you think about it in the long term, we recommend replacement.

I was looking at ESTRELLA's Fuel Cock, and I was wondering about SR400 too.
I'm not seeing any glitches at this point, but I'm concerned that there may be some in the near future.


This one is also dirty near the Fuel Cock, I could see Gasoline seepage, so let's replace it!
I feel like I should just replace the internal Packing, but I decided to replace it still wanting to continue to ride.

Like ESTRELLA, SR is also a negative pressure carburetor.

Fuel Cock (Negative Pressure Cook)
...Cook is a Fuel Cock that uses air pressure.
The Motorcycle is divided into Parts called Fuel Tank (Fuel Tank) and Fuel Cock (Fuel Cock) that connects the Carburetor.

Cook's Place.
The parts called "Fuel Cock" are attached to the bottom of the fuel tank.
Applies to vehicles equipped with a Reserve Fuel Tank.
Mainly Carburetor cars.


How Fuel Cock works.
It is generated when the engine is running and the air mixture is inhaled. "Negative pressure" Gasoline flows through the open valve by
Simply put, if Engine is on.
→Gasoline flows.
When the Engine stops
The flow of →Gasoline stops.

[If the Fuel Cock malfunctions...
Fuel supply is not normal, causing Engine malfunction or fuel leakage.
→Idling unstable, frequent stalls, Gasoline smell.
...Gasoline leaks.
→ Flammability hazard.

Fuel Cock failure can occur over a long period of time due to deterioration. The following are some of the causes.

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.
I think this is also the case for SR400.

A simple explanation is that Cook = faucet.
You know how sometimes you find water leaking even though you've tightened it properly?
Material inside:It leaks because the RubberPacking has deteriorated and is no longer sealed.


Although the replacement is not large, there are many steps involved.

How to Replace Motorcycle Fuel Cock ~SR400~

(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.
↓
(2) Turn off Fuel Cock.
↓
Pull out the Fuel Hose and the Negative Pressure Hose.
Please check that there are no cracks in the hose.
↓
Place the Fuel Tank from (4) on a step Ball or soft place.
↓
(5) Replace the Fuel CockAssy.
↓
? ?→? Return in this order to complete the process.

〜After replacement
◎Of course, the Gasoline blotch near Cook is gone.
◎Improved a little Gasoline smell.

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. View detail

Heart of the Engine

When I replaced the cell starter the other day, there was a situation where I had to open the crankcase, and since there was an oil pump in the vicinity, I replaced it as well.

Oil pump
The passage through which engine oil flows is the oil line, and the oil pump is the starting point of the oil line.
The →Oil pump is the heart of the engine, and if this part fails, the circulation of oil inside the engine will often fail.


What is the role of the oil pump?
Oil pump works to suck up and circulate oil to reduce friction between Transmission GEAR and Bearing.

It is a very important part, but it is also troublesome if it breaks.
It is the cause of life span and breakage,
Life of the Engine oilPump.
The service life of the engine oil pump is almost the same as that of the engine. 。 As with the Engine, the Engine oil must be changed with proper Timing in order for the Engine oilPump to work properly! 。

Cause of failure
If the engine oil replacement is neglected for a long period of time, the engine oil pump will fail, which will eventually cause the engine to fail.
What exactly happens?
If the oil does not circulate well in the Engine, the →.
The rotation of the crankshaft is transmitted to the GEAR attached to the splines to rotate the oil pump. 。 Oil is pumped from the inside by rotation. Therefore, if GEAR does not rotate due to damage to the splines, the oil pump will not operate. In other words, oil will not circulate inside the engine. 。 Oil does not rotate.
⇒ causes seizure.

In my case, I'm replacing it for the purpose of eliminating uncertainty, not failure, but the way to determine if it has failed.

Symptoms of malfunction
(1) White smoke rises.
(2) Spark plugs are covered.
(iii) Engine burn-in occurs.
Even if you think that the oil pump may be faulty, it is also a high hurdle for a beginner to disassemble it immediately to check if it is normal or not. 。
It may be simplified for this reason, but we will first inspect it as follows 。
Inspection Method
○ ○Idling the exhaust pipe and hold your hand over the exhaust pipe to see if Oil adheres to the pipe.
→ This is the easiest.
→I felt a little bit Oil-like (laughs).

Oil pumps are not often disassembled and repaired in a manner that is → difficult.
Therefore, it is better to replace the oil pump itself.

How to exchange.

(1) Remove the Oil.
↓
Remove the Crank Case Cover.
↓
Remove the oil pump.
There is a screw that holds the Oil Pump Gear in place, but since it is an integral part of the Oil Pump Gear, remove the Plus screw.
Screws are hard, so use a screwdriver to loosen the screws.
↓
Install the oil pump with new gears and tighten the screws.
↓
(5) Attach and tighten the Crank Case Cover and Gasket.
↓
(6) Insert new Oil. Done.

There is no particular effect, no Oil from the Exhaust System, no White Smoke, that seems to be the effect.
It is similar to the heart that pumps Oil into the Engine, or in humans, the heart that pumps blood into the body. View detail

Bolt is becoming White muddy.

The bolt has turned cloudy white. How many years ago was the bolt manufactured? I purchased the Titanium at the same time as the POSH shaft, but this product is a Blackish Titanium and does not match the shaft. View detail

Tightly sealed. Very easy to use and durable, if you are not sure which Oil Jug to choose, this is the one.

There are many Oil Jugs out there, but I bought this one because it has a lid and is just the right size.
There are three points to this product. The product does not need to be wiped clean every time, the liquid can be left in a sealed bottle, and spare parts are available.
The work is faster and less garbage is generated because there is no need to wipe up every time when the work is finished.
In particular, the ability to leave the liquid in place is quite an Advantage, and can be used, for example, in the following ways

1. Prevents Garbage contamination during work.
2. Oil replacement work can be done across the day.
3. Easy to reuse waste oil
4. Easy transfer of fluids

All items are related to personal DIY.
The first is obvious, but the second is more convenient and easier to set up for DIY. Even if it is already dark when the last injection is to be done, it can be carried over to the next day or even a few days later. This is especially useful for cases that take a long time to inject, such as Mission oil for cars.

3 is also important for me personally. For example, it is useful when maintenance around Overhaul or Clutch requires removing oil once, but you want to reuse it instead of using new oil.
The oil is a typical example of a motorcycle rider's sense of value that is easily bugged, but if you think about it calmly, it is very expensive, and I don't feel the need to replace it with new oil every time, especially when the clutch cover is opened.

4 was a useful Point that I realized after I bought it.
For example, for waste oil disposal, we used to make a waste oil pack, but now we receive the waste oil in an oil pan, return it to a jug, and then put it in a plastic bottle and take it to disposal. This kind of troublesome liquid transfer can be done cleanly.

Items is useful, but there are drawbacks.
First of all, the base of the nozzle sticks out in the bottle and leaves oil. This is not good.
Also, the Mesh at the base of the Nozzle is subtle. It reduces the injection speed.
The protrusion is not a functional part, so opening a horizontal hole may solve the problem.

A weak point in durability "Nozzle" I have been using it for about 4 years and it hasn't cracked.
This is a good product that I can highly recommend in JUG. Seriously recommended. View detail

Thin, lightweight, compact, easy to carry, and safe to carry

It is thin, lightweight, and very compact when folded, making it a must-have when I go out. It is very useful from spring to fall when the temperature difference is very large, such as when it is cold in the morning but hot during the day, or in summer when you are in a high altitude and the temperature is low, or when you encounter chilly conditions such as fog. In winter, it is good to have one more layer when you don't want to be overdressed but are a little worried about warmth.
It is more of an Emergency product, and if you expect to wear it in the inner room, the texture and design are like this, but the performance is sufficient for your needs.
Actually, I have been using a collarless version called "YKM-212" by Yamashiro before I bought this one. I bought this one because it is more compact when folded up, and this one with a hood seems to have good windproofing properties around the neck.
On the other hand, this model with Hood is designed for outer wear as well.
The Level is not a good place to stay in Parenthesis, but it is not embarrassing to take off your jacket and walk around during a break.
There are many thin, windproof innerwear products of this type, but I think that Yamashiro's silayed Nylon is the thinnest, lightest, softest, and most compact. I think it is the thinnest, lightest, softest and most compact. It is a recommendation for those who want to keep their luggage to a minimum. However, the price of this Hooded bag is a bit expensive. (List price) I would not say that it is a bit cosy.
Sorry WeBig, but if it's the lowest price sold at another Site, the cosmetics are good. View detail

It got brighter.

Replaced Headlight Bulb on Z125PRO.
The purpose was not only to make the engine brighter, but also to reduce the load on the battery (power saving). The Z125PRO had LED lights from the beginning, so there was no need to replace the tail lamps. I thought about replacing the blinker light because it has a normal bulb in it, but I decided not to do it because the blinker relay seems to be built into the meter and it would be complicated to change it to LED. This time, I decided to replace the Headlight Bulb and the Position Lamp with LEDs, and for the Headlight, I chose this product, which was the cheapest among the Sphere Light products.
The replacement work was as simple as removing the headlight cowl and replacing the valve with the original one, and since the valve is compact, there were no problems with installation.
As for the feeling of use, the light is bright enough and feels very bright, probably because the light is whiter. I was able to drive safely at night. I was not bothered by the dispersion of the light. Unfortunately, there was not enough of an energy saving effect that I could really feel.
Compared to when we replaced the LEDValve on our ZRX1100 a few years ago, low-cost products are now on the market, and the hurdle for replacement has gone down. If you are concerned about the brightness of your lights, we recommend replacing them with LEDs. View detail

SportsBoots for the best STREET!

I bought them as summer Boots because I switched to a Motorcycle where the exhaust heat directly hits the ankle area.
Since this was my first time to use this kind of racing boots, I was confused at first by the fixed feeling and shift change, but I got used to it as soon as I started running.

【good point】

What's not so great about it
The price is too high!
Boots in doesn't show off the cool design….

The size is typical of a slim foot shape for overseas, similar to Nike's RunningShoes when compared to Sneakers. If you have a high instep, wide and fat calf, it may be very tight.
I took a gamble and chose the usual Size, but it was Exactly the Tight Fit feeling. View detail

Low price! It's helpful for old car riders!

I recently acquired a 50 year old Van Van 75 and have spent a lot of time and money to make it look like a new car. Thankfully, the engine was in great shape, so I just put in air cleaner, cleaned the exhaust system, changed the mission oil, and didn't have to touch the engine or carburetor. I was surprised to see that the plug was tightened so much. When I finally took it off, I found a plug that looked like it was 10 years old.
I replaced it with this plug, and the engine sound seems to be much lighter. I also made a Vehicle Mounting Tool Set and installed it with the spare plug since I didn't have any tools to mount it on the car. All that was left was to put the spare Gasoline in the bag and install it.
It will soon be fully restored. View detail

It would be useful to have when pinching round objects with Vise

I had only had a Mini Vice until now, but when I needed to do some welding, I bought a medium sized Vise. I bought it because I thought it would be useful.
I wish the material was sized to fit the groove of this product, but it is a little difficult to use when the angle is not right. Also, this product has a strong magnet that sticks to the vise, but it is a little troublesome to use it after aligning the teeth of the upper and lower jaw because the teeth of the upper and lower jaw seem to be misaligned and the tooth sides are not aligned properly.
So, it is not suitable for all purposes, but there will be several times in a lifetime when it would be very convenient to have it. The color is Kawasaki green, which I personally like, but there is no Kawasaki motorcycle at the moment, so I am not sure. View detail

I think those who do maintenance will feel the benefit.

When you park a Motorcycle, you often say STAND, don't you?
There are Center Stand and Side Stand in STAND,
In this case, the Center Stand was rusted and I was worried about it, so I will replace it.

What is Center Stand?
The Center Stand is a stand that allows you to park your motorcycle in a more stable and upright position than the Side Stand. 。 It is useful for parking bicycles for long periods of time and for maintenance.

The Center Stand looks and feels firmer and heavier than the Side Stand, but what kind of merit or demerit does it have?

[Merit]
(1) Because the vehicle can be parked in an upright position, there is no burden on the tires during maintenance or when storing the motorcycle for a long period of time. 。 Indoors, where there is no wind influence, there is less Space for storage.

The motorcycle driven by the drive chain needs to be adjusted, checked, and lubricated on a daily basis. Especially when checking and adjusting the slackness of the chain, if you stand the motorcycle on the Center Stunt, you can do the work quickly without jack-up time or using special tools.
Center Stand can be said to be a STAND that can take the place of Jack. 。 Since the rear wheel is floating, puncture repair can be started simply by setting up the STAND. It is said that the rear wheel is the easiest to puncture in front and rear tires, and when the Center Stand is set up, the rear wheel floats, making it easy to find and repair punctures.

The work related to the rear wheel, such as adjustment or replacement of the rear suspension, replacement of the sprocket, and replacement of the drum brake shoes, can be done with or without the Center Stand, depending on whether or not the Center Stand is installed. In addition, it is very useful for bikers who want to maintain their motorcycles by themselves, such as oil replacement, oil filter replacement, and brake fluid replacement, because the chassis is standing straight.

If you look at it in terms of doing→maintenance, there's a lot of Merit, but there's also Demerit.

[Demerit]
If you use the Center Stand when strong winds are blowing in a typhoon, the motorcycle will be pushed by the wind and the tires will float, reducing the ground contact area and making it easier for the motorcycle to topple over. 。

The solution is to use the Side Stand instead of the Center Stand, which stabilizes the vehicle body by supporting the front wheel, Side Stand, and rear wheel at three points.
In my case, I put the GEAR in first gear with the + there and park it so the Tire doesn't move! 。

Installation method ~ESTRELLA~.
(1) Jack-up to float the body.
↓
(2) Spring with Cover, (It's fucking hard...)
↓
(3) Hang the Spring on the Body and hang it on the Motorcycle side.
↓
(4) Align the bolt holes and insert the driver into one of the holes. （Insert and tighten the Bolt while shaking the other hole with the bolt (to prevent gapping). 。
↓
Insert the pin.

The assembly itself was not difficult, but the springs were hard and it was very difficult to assemble.

■ After replacement
◎Maintainability has improved considerably 。
I feel that the weight of the STAND and the fact that the STAND is stored in the center of the car body may be contributing to the stability of the car body.
▲Bank angle is obviously reduced. → If you lean the vehicle too much to turn, it will rub.

However, I think that the increased maintainability is a major merit, since the vehicle is not an aggressive type of motorcycle. View detail
