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.

Coil new OEM Cable new OEM Cap new OEM 5kΩ.
Gap 12.2mm! No Taco MeterNoise
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.

It doesn't feel as good as I had hoped.
First of all, despite the fact that it is claimed to be a car-specific Harness at this price, the Flat Terminal plate thickness of the CoilWiring does not fit (the product is too thin to mate) and needs to be modified.
I think the installation itself can be done without any problem if you can put down the tank by yourself.
Knocking at very low speeds has been reduced and the acceleration has been improved. And that's about it.
The Plug is NORMAL, so I'm looking forward to seeing how I can switch to BRISK's LGS.

cb400ss uotani power coil compatibility
This is a car with CB400SS skatune work done. I replaced it with a power coil as the starting performance and the coil did not bounce well. But the startability is really good. cb400ss Skate tuned vehicle. Startability and coil are not splashed and replaced with power coil Uotani bracket There is no place at all and it was fixed with cable tie. But I really like starting. translated by Google Translator View detail
No dramatic change
KZ1000LTD(OEMFull transistorSpec. ) Installed this PowerCoilKit. My Motorcycle is PointSpec. It would definitely be a Full powerKit, but I thought that there would be a dramatic difference just by strengthening the spark, I made it to CoilKit, which costs half the budget.
As a result, I felt acceleration was powerful, but I did not feel a dramatic difference than I thought.
I regret that I should have made Full powerKit ... I regret a bit, but I was worried about when OEMCoil was old and when it caused old malfunction so I decided to think I replaced it with a new Coil.
If you have plenty of budget, I recommend Full powerKit.
