This is not the only thing I changed, so ….
Installed on 12VMONKEY.
I purchased it this time to improve a mysterious starting problem.
Replaced by Uotani→Uotani.
So the effect of the utani itself is unknown.
The first generation was also at the same time as the Head replacement, so I didn't know much about it.
Well, I like the way it looks, so it's ok.
However, it is also compatible with Tachometer and CDI, and my
In this case, the Tachometer malfunction did not stop even if a resistor was inserted.
Change to CDI for a certain Chinese Engine and say it settles down.
It was a strange event.
The compatibility of each item can only be determined after installation.
You should buy with your head in the sand.

Startability and Idling has been stabilized!
I replaced it with IGCoilRefresh on an older vehicle (TT250R) and the results exceeded my expectations.
I have installed the full powerKit and Ignition coil from Uotani on many different types of cars, but this was the most effective!
In NORMAL, pull the Chalk. I had been repeating the same cycle and warming up the car for about the third time, and it seemed to stabilize somehow, but after I switched to the Utani, it really started to work. Cultotototot." and Cell1 from cold time without even pulling Chalk was a surprise.
I was impressed because there is almost no difference in temperature since we tried it before and after the exchange on the same day.
I changed the plug and plug cord together, so there is a possibility that the degradation of NORMAL was severe, but I am Large satisfied with this result!
These parts reminded us that when maintaining or restoring an old motorcycle, it is essential to refresh the ignition system.
*I haven't had time to ride it, but I'm wondering if it's Torque up enough that it doesn't feel like an amateur? I hope so.

Stable Utani Coil
This is the 4th vehicle for us to install this system, including MONKEY, Wolf200, RG250Gamma, and now 500SS (H1F).
I don't expect dramatic changes, but it is a reliable Brand and I will continue to use it.

Failure to bring out the performance. 3rd Consideration Impedance inconsistency.
This is my third post on the failure to bring out the performance of SP 2, which GapClearance lost to OEM. I have very little knowledge of electromagnetics, but in layman's terms I have come to the following conclusions.
Impedance mismatch with CDI reduced the primary current and the secondary voltage.
Since the primary Impedance of the Coil is determined by the induct Chest on the primary side of the Coil, I think such an external Coil will significantly affect the running if you are unlucky, whereas the OEM is designed for overall optimization with Igniter+Coil.
Since Indak Chest, which is originally Coil's most Large cut Spec. is calculated from the Impedance matching condition, I think it is safer to choose the OEM with a matching design as an option.

We could not bring out the performance.
Below is the same as another post until about halfway through.
I have since replaced the Plug Cable with a Utani and MSD and measured the Spark Limit Electrode Clearance, so I will post additional results.
The CDI is a Posh Analog/Digital switchable ignition system.

Octopus Meter is a DN in Mukawa.
What a surprise, the OEMs were the strongest dunce in the results.
All Uotani had the narrowest Gap, and I expected Noiseless for MSD, but no.
Considering that the spark voltage hardly changes even if the secondary side resistance value changes Large where the secondary side current is only a few mA, I now realize that Gap and Noise are determined almost exclusively by Coil characteristics after all.
I think that the Uotani SP2 is incompatible with my CDI, or maybe the CDI can't bring out the full performance of the Uotani SP2. Well, if the Spark is flying close to 10mm, I can run well enough,

I'll wait and see a little more.
The CDI is a Posh Analog/Digital switchable ignition system.
The Spark limit with the new OEMIgnition coil, Cable, and Cap was 11mm electrode Gap, while the SP2 with NGKRacing cableCR3 resulted in 10mm.
One YouTuber's verification stated that replacing Cable from NGK to Uotani produced a stronger Blue Spark to see with a wider Gap than when using OEMCoil.
Also, CHATgpt's answer may not be correct, and I don't know much about electromagnetics, but I answered that you can't get the true Spark without optimizing the properties of Coil's Indak Chest and Cable's Material, resistance etc.
Based on the above facts and theoretical answers, I would like to replace Cable with Utani.
The DNTachometer needle from Mukawa, which is used for signal extraction by wrapping around the Cable, is extremely violent. I will change this needle to Cable from Uotani and see how it goes.

If you want to replace a worn-out Coil
I feel that it has more starting power and strength, which is true to the rumors.
It may just be that I feel that way because I am replacing a weak coil, but if I were to buy an OEM coil, I would rather buy this one because it gives me the feeling that I am touching the Motorcycle.
The work is also easier than you might think. It can be replaced immediately.

good-looking
I was worried about where to install it. I bought it just for the looks. I haven't driven much since I installed it, so I don't know how well it works. View detail

The installed product seemed to be in bad shape, so we replaced it with a new one.
I feel that the feeling ignition system is now ignited more powerfully.

SPII High Power Coil
About quality and texture The quality of the product is very high About the feeling of use I get the impression that idling is stable. Products to buy together Coil cable, bracket Difficulty of installation It can be easily installed by using a 7mm coil cable, or it is not easy to process the cable Cost performance and comparison with other products I used an ig coil and bought it for a startup, but I don't think I felt the difference from the ig coil. The price is twice as high as the components, but it becomes three times more expensive About shipping and packaging It took a week and the packaging is great Any concerns, cautions, or advice when purchasing I recently changed it to ngk powercable, but I bought it to increase the number of startups, but the app100 exclusive product was expensive, so I bought SPII Universal High Power Coil and Monkey Frame Mounting Bracket together and installed it well. The ngk cable combination was installed well installed View detail
Great coil performance surprised me…
Never heard of this brand here in the U.S. I was gonna buy the posh brand or another brand I knew. I figured be different an gamble on this SPll coil. I very happy I did. My Honda dio idles better and feels more responsive thru the rpm range. See how it gos on the long term but so far so good. On the model I choose Monkey but my bike is a Honda dio Af18 View detail
D Attached to Tracker and seeing the effects!
[How is it used?
Vehicle applications:Motard race, Touring
Used for about 6 years, together with NGKPower cable.
Was the one you received as per Image?
The mounting bracket is solid and will not be damaged by vibration. The mounting bracket is solid and will not be damaged by vibration.
The size is slightly large when the bracket is included, so it may be difficult to find a suitable mounting location. I felt that it would be difficult to find a suitable mounting location.
Was the installation difficult?
If a person who is able to customize electrical components to some extent can work with the service manual, he/she should be able to do so without any problem.
However, the D Tracker (KLX) The mounting location of the product on a PC is difficult.
We managed to fit the OEMCoil installation in the OEMCoil installation location, but we did the One Side in a Hemp palm dock. (Using the included Bracket.)
Even the inHemp palmock installed and withstood use with no problems. Although it was installed in a location where heat is generated, there was no thermal damage, and it was large and sturdy.
How was your experience with it?
The feeling I got from using it was that the torque feeling was increased in all areas.
In particular, changes in Axel opening at startup. (You don't have to open it very often.) was remarkable.
I think this is a good part that leads to a more relaxed driving experience.
Even if the D Tracker is used in a race, it is inferior to the WR250X in terms of power in the production car class.
Race requires replacement every Season. I had no such problem.
There were no problems when used with NGK Ridium Plug.
[Included Parts:were they on?
Yes. Please refer to the product description.
[Was there anything that disappointed you?
None

Good feeling
I've been feeling a lack of power lately, so I thought I'd try replacing the Ignition coil just in case.
It is difficult to feel the difference between this kind of parts, but it is good to feel the fire is flying at high rpm.
I didn't use the Blue Plate, but made a Bracket to fix it.

Startability, Torque up
I've had it since my last GB250, and it's clearly improved the starting performance and thickened the torque!
This time, I think that there is a synergistic effect because I put NGK Power cable and Idyllium Plug into TW225, but I will recommend it to everyone because it is an important power up of ignition!

Idling has gone quiet.
I bought this product because I own an older Motorcycle and was concerned about the decline in power of the OEM Product.
Quantity:The Set even includes the Star, so if you have a Motorcycle with Space, it will be easy to install.
From what I've seen of Spark, it looks like it's changed from a thin Spark to a strong Spark.
The blink at high rpm also seems to have improved a bit.

It is difficult to install.
I installed it on my 110cc Bore up MONKEY. It was very difficult to install. The NGK cord was too thick to fit in the CoilBody without modification (I had to cut the cord to make it thinner).:The Rubber Boots also did not fit the NGK cord very well, and I had to force it in, but the Boots ripped in several places. I thought there was a problem in the design.
I bought some parts from Home center and made a lot of effort to install the motorcycle body.
I am satisfied with the function. The explosive power has been increased and the response to the Axel has been improved, and the combination of Takegawa's Rotor, CDI and Yoshimura cap seems to be a good match.
