AS Uotani SP?Plug Cord Set (for 4Plug)
It's been about 10 years since I installed SPII on my CB750FB. this is the second time I replaced the plug cord. idling and engine starting became unstable, so I replaced it after 5 years.
The terminals are pre-plugged into the plug cord and the quantity:Waterproof Cover can also be attached smoothly to the Plug cord and Waterproof Cover by spraying Silicon Spray.
After the replacement, the engine started smoothly and idling was stable without any change in Carburetor settings.
Carburetor is CR29 + M Nozzle, ignition system is MSA + V-UP16.
In order to eliminate the anxiety of long touring in older vehicles, we believe it is safe to replace consumable parts that are of concern as soon as possible.
It's not cheap, but it's a good thing to be prepared, so you can enjoy your motorcycle with peace of mind this season.

Uotani SP II
Conversion from Mukawa Power Coil to this product
Torque goes up a bit!
One shot of Engine start!
I was worried about the malfunction of the Mukawa F-computer.
Drove 50 km, no problems.
However…
It's a pain to remove the cowl.

Purchased due to Plug cord change
I bought a battered 900SS (900SL) and am Restore.
I have been using AS Uotani's SP2Full powerKit for over 20 years and have been using it all this time on my bimota db2 (DUCATI 900SSEngine equipped car).
We transplanted the engine to the 900SS that we are restoring, and since we are taking this opportunity … we also replaced the plug cord.
The old plug cord had the connector that came with the kit crimped onto it, but since it is not possible to reuse it when replacing the plug cord, we purchased the connector that is available as a for repair kit.
The Coil used in the for DUCATI kit is a 1P independent type, the same as that used for the 4stSingle engine.
The connectors seem to be the same as those used in DYNA and other coils, but I didn't want to use a different size, so I decided to use the AS-Uotani OEM Product, although it is a bit more expensive.
The same shape is available from several manufacturers, but the lowest price is probably the one made by Posh (quantity).:(1 Set of 2pcs. around 500 yen), but AS Uotani's products are available in Quantities:2pc. It is a high-end product that costs more than 1,200 yen for a set.
It looks like the same thing no matter how you look at it … well, just in case.
As a Connector, it is very ordinary, so there is nothing special to say about it.
It takes a little bit of hang to Crimp, but you'll just have to Crimp hard on your own....

Even with the FCR Carburetor Body, there is no creaking, and it starts right up.
It sometimes took a long time to start with the FCR Carburetor Body in winter, but after installing this product, it starts at once even at a temperature of 0 degrees Celsius.
Of course, I charge the Battery regularly, but it is nothing compared to what it was before I installed it.
The driving has also changed.
It feels like a powerful acceleration without changing GEAR.
This is a combination with NGKPower cable.
Cable thickness was no problem, and I was able to install it without any particular difficulty.
It took about two hours because of the particular way the Cable was threaded and the height adjustment.
I am an amateur and I think it would be faster if a PRO installed it.

An unlikely component
Plug cord was installed with a new one and a kit rack to attach the utani.
I had to adjust the length because it was a UniversalPlug cord, but it is easy to tell which cord is which, and the yellow color is subtle and appealing.
Since the cord diameter is full, it takes a little hang to fit.

Ready-made is good.
I was thinking of adding a NumberRing to the code for the installation of Uotani, and since I didn't want to do it by hand, I looked for one and found just the right one.
It is Exactly to the code diameter and does not Gap.

Strong Spark
It is a 40 year old HORIZON, so the number 1 was well CUBed.
The price was a little steep, so I couldn't afford it, but I'm glad I took the plunge and bought it.
In fact, I regretted not having put it in earlier.
The stronger spark could be felt by simply twisting the Axel.
Idol has stabilized and I think fuel economy has improved. I think so.

Used when replacing Plug cord
It is used in GPZ900R.
We have installed AS Uotani's Full powerKIT and used it to replace the Plug cord.
This time, the plug cord is NGK's power cable, which is specially designed for each model of car. It was quite difficult to stick the cord into the RubberBoots. 556 was not enough, so I sprayed CCIMetal rubber and the Plug cord went through the Rubber cover.
One thing to note is that it is not possible to crimp the terminals neatly when crimping.
From the beginning To some extent." It is important to keep it bent and crush it firmly at the end.
It is a must-have component when using the Uotani Coil.
I think it is a little expensive, perhaps because it is a monopoly. It would be helpful if the price were lower.

Ignition System Refresh
I was having trouble starting the car in the winter.
Standard Plug BP5HA to NGK Iridium Plug
Ignition coil for MC47 (Standard Tune in MC22)
OEM Parts still available for purchase.
Plug cord for the Uotani SP 2 (Plug cap is OEM)
Material:Silicon is soft and easy to handle.
Remove the OEMPlug cordassy from the Ignition coil.
Disassemble the Plug cap and Plug cord.
Cut the UotaniPlug cord to the length of the OEMPlug cord.
If it is MC22, 1m will be enough.
Assemble the plug cord and attach it to the Ignition coil.
Caution!
The NC47Ignition coil is plugged in #2 and #1.
Since it is shallower than MC22Ignition coil,
It will be a little longer to match the OEM Length,
Adjust the length.
Uotani SP2 + UltraSilicon plug cord is ideal.
It is expensive anyway, so I think it can be implemented with a low budget and be effective.
Startup is better and Idling is more stable.
The 6-speed 40 km/h is also easier to ride.
Torque did not experience any thickening.

I think it depends on the individual Engine and Carburetor.
It is effective enough.

It has not been driven, but I am satisfied with the cost.
I purchased this one because the parts are no longer available.
Installation was also easy after searching on the Net.
It is not running, I just applied Engine,
It went on easily without any CUB.

Uotani sp2
Idling is unstable, so I bought it to improve it.
My impression is that the Idling's unstable parts are much better than before. It is more powerful, and the acceleration and startability are much better.
The price is hard to reach, but I thought it was an acceptable price point.

Without Sticker.
Without the Sticker, it looks like an ordinary Coil.
The coil was originally inside, but now it is on the front side due to a change in the direction of the carburetor, so I put it on because it was lonely if it was pure black.
This will increase Power by 8 percent, just like the consumption tax rate.

I should have put it on sooner!
The rev adjustment should be set with a generous amount of rpm.
At the RPM of the setting, Limiter works!
You will be surprised!
You should be careful.

Wouldn't it be nice if it was affixed to CoilBoth Sides?
I purchased an additional BodySticker for my GORILLA, because when I installed the Body using Minimoto's Bracket, the BodySticker was facing away from me (stuck on the One Side). I recommend you to buy it at the same time with Body. View detail

Great
Clearly better starting. Ignition timing can also be adjusted to suit the Motorcycle. View detail
Very effective Large!
It's very effective Large!
The blow up around 6,000 rpm was not so good, but after using the Utani sp2, it blows up smoothly.
The Engine has also improved!
We do not know the fuel consumption!
I don't care about fuel economy as long as I can drive comfortably.

For strengthening the electrical system of out-of-print cars
[How is it used?
AS Uotani was installed to strengthen the electrical system of YAMAHA XJR400R.
We had the impression that the electrical system was weak due to the fact that the Motorcycle was 15 years old.
As AS Uotani's Manufacturer, we recommend the use of NGK Iridium Plug and Power cable together, so we recommend the use of NGK Iridium Plug and Power cable together.
We decided to install NGK Iridium Plug and Power cable in addition to AS Uotani.
Was the one you received as per Image?
The 6V MONKEY/GORILLA Main Harness side was surprisingly long.
Was the installation difficult?
I think the installation is quite difficult. It would be tough for those who have never tinkered with electrical systems before.
I have to modify the OEMCase to fit the XJR400R because the OEM installation position is smaller than the OEM position and the coils are larger than the OEM. So I decided to modify the OEMCase.
For detailed installation, please see the video.
How was your experience with it?
Power has increased dramatically, partly due to the use of NGK Iridium Plug and Power cable together.
In particular, I have the impression that Torque has increased and the capacity to pull from 1st gear has increased. Perhaps because of the increase in relative power, I feel that I have fewer opportunities to use 6th gear on public roads.

No special requirements.
