Nibbi ignition cap replacement

Thebrozzanator · 08-26-2020, 12:01 AM

I replaced my old worn out cap with a nibbi cap. It seems to of woke the bike up significantly. I can pull hard through the gears now. It feels so snappy and shifts so much smoother with the nice power transfer. I bought a better ignition coil I just need the proper electrical connectors. I'm curious to see if that makes a big difference as well. I definitely recommend doing this right off the bat with the Brozz!

Could you post a link to the Nibbi part you used please?

**JerryHawk250** · 08-26-2020, 10:05 AM

The performance gain is probably because it's a non-resister cap.

RedCrowRides · 08-26-2020, 05:59 PM

Ah, is he talking about a spark plug cap / wire ? Lol

gwowzer · 08-26-2020, 06:07 PM

Yes, link, please!

gwowzer · 08-28-2020, 10:08 PM

So I have a few questions relating to all of this. I just purchased this ignition coil:

https://www.amazon.com/gp/aw/d/B07ZC...?ie=UTF8&psc=1

I haven't sourced a spark plug cap yet. Is it a big deal to use a resistor cap vs. a cap with no resistor? Any harm come from either option?

Also, I was planning on just going down to the auto parts store to find a cap and connector.. does anyone have a link to one that will fit this part and the plug?

gwowzer · 08-30-2020, 11:17 PM

So just bumping this up hoping for some input... I think that ignition coil I linked is ok, please advise if not.
I did find an old thread by Megadan where he used a spark boot from a Goldwing and replaced the resistor with some twisted up wire...
I guess the main question I have is if there is any harm in removing a resistor from the cap, and what exactly does the resistor perform?
As cheap as these bikes are, I don't understand why they would install an extra part like a resistor if they didn't have to pay for it. So it must serve some purpose.
I assume it is because these have CDI ignition and they are trying to even out the capacitor discharges for a consistent spark fire.

https://www.amazon.com/Replacement-P...ibi+ign&sr=8-5 this is the coil I bought. I just used the cap. I just received the electrical stuff to swap it out. Curious if it will continue to gain more power. As for the non resistor cap I'm not sure of the difference myself. I feel like my bike pulls like an old dirt bike now with how snappy it is. Once I swap out the ignition coil I'll update of it works and if it's better. The NGK spark plug cap I bought would only receive the big part of the spark plug not the screw part on top. The nibbi was a screw top receiver. So does this make it any different per say of the non resistor or resistor cap. How do you know the difference?

Got it so from what I'm gaining so far is running a resistor plug with a non resistor plug cap should be fine. As long as there is some type of resistance. I'll keep reading but I'm sure it will be fine. I threw an NGK spark plug cap I bought as well a resistor cap. With the resistor plug. It didn't seem to run as good as it did with the nibbi spark plug cap. I'm guessing the Nibbi one is non resistor.

gwowzer · 09-01-2020, 11:28 PM

It is a capacitor discharge ignition so resistance is needed to "smooth" the flow of electrons to the spark source. I understand that part.
As Megadan explained, one or the other, but not both, either way. Clear as mud, right? Lol.
A resistor is needed in the circuit, either on the plug cap or built into the plug itself.
I installed an iridium plug with a resistor going off the part number.. So good to go with a non resistor cap. Or I could switch it around and run a non resistor plug and install a resistor cap.
Either way, from what I am gaining, the worst you can do is run non resistor plug and a non resistor cap, possibly gaining a hotter spark, but, putting the CDI module at risk of a premature failure.

Does anyone know if the stock Brozz 2020 cap is a resistor included module? If that is the case, maybe I'm doubled up on the resistors.

You can find out with an ohm meter. Measure resistance through the cap. If you have high resistance, there's your answer. If it is zero, or near zero, there is also your answer.

Nope, it's to cut down on RF interference, similar in function to a choke in an electrical circuit.

Thebrozzanator · 09-02-2020, 11:24 AM

Very good info and yes as clear as mud! Lol I do believe the stock Brozz has a resistor type cap. Only reason I'm saying is because the stock plug that came in it was not an R type plug. So if you are running the NGK R plug like I was then you are most likely running double resistor. That's why I felt a slight improvement plus my old cap was a little weather worn. On Megadans post it did say there would be no performance enhancement. So I'm guessing it's just a better spark with a new cap and not being double resistor. Never studied any of this stuff all learning for me guys!
