Boost Your Motorcycle’s Performance with This CDI! "DIY CDI box"

[@MrWolfDiy]

Hello, friends, if you have a weak spark at the output, or no spark at all, change the diode, D5, to 1n 5408. Good luck ♥️

[@donwright3427]

Capacitance discharge is the best way for us to get the information to tell the spark to go in the engine when the clock is right time every round of the cyliders

[@Customhand]

Congratulations, It looks great, I have to try it. Thanks for sharing 🙏

[@MrWolfDiy]

You’re welcome 😊

Great, thank you for that

[@MrWolfDiy]

You're welcome!

[@macgyverdroid]

Cdi controls the ignition timing too not just to ignite only

[@Bias_Prineus]

If it's low on power, it will not show a difference 😕

[@MrWolfDiy]

in fact ,It is responsible for enhancing the ignition spark and acquiring precise timing via the crankshaft position sensor.

[@tayyabibx]

since you have multiple CDI videos you should assign model number to each for example AC7sb AC = it's an AC CDI 7 = average spark length is ~7cm s = sports variant with adjustable advance, f = fixed advance, n = no advance b = just simple a-z counter, b indicates 2nd revision

[@MrWolfDiy]

That was an interesting idea, thanks.🙏

[@TiktokGods-gq8ri]

​@MrWolfDiy can you make one DC cdi?

[@MrWolfDiy]

Already made available in channel

[@ElvisGTARev]

Topado meu amigo, falo do Brasil!

[@MrWolfDiy]

🤝

[@dadandkids5028]

The CDI controls advance as well in some cases. Did on my Kawasaki.

[@ravijayasundara-eu9gf]

That's interesting. How do you do that..? Can you please explain it for all of us please.. Thank you

[@ametti000]

All factory ignitions do. Higher rpm = more advance.

[@ravijayasundara-eu9gf]

But it's not happening in most motorcycles.. Very low angle advancing.. But with mechanical advancer units we can obtain higher advance angles which means more power... But with basic most common cdi units i can't understand how its ignition advancing going on... But with mechanical advancer systems its very clear.. If you know something about cdi advancing theory please be kind to let us know.. That would be great.. Love to hear from you Thank you ​@@ametti000

[@Turkeydinner]

Can you explain the pickup requirements? I'd like to try making a CDI for my outboard motor. It's a 2 stroke that is currently using points. I watched another of your videos explaining how to make a 12VDC 3 cylinder CDI. I'll definitely be watching that video a few times.

[@MrWolfDiy]

greetings To convert a point breaker engine to CDI, significant changes are required: removing the old system and installing a crankshaft position sensor (pickup), and adjusting the timing so that when the piston reaches top dead center (TDC), the pickup is triggered. Additionally, a 12-volt coil and a CDI IC are needed. By following these steps, you can upgrade the old point breaker system to CDI and improve the engine's performance.

[@VixNoelopan]

Schematics, please!

[@MrWolfDiy]

As I mentioned before, this circuit didn’t actually have a schematic. In fact, I reverse-engineered an OEM CDI, opened it up, and made some modifications to increase power... You can draw the schematic yourself based on the circuit I created.

[@mobilgin]

Is this CDI ( in video) it is AC or DC model ?

[@MrWolfDiy]

AC

[@3333arslan]

Very good, please provided circuit diagram

[@MrWolfDiy]

The diagram is the same as the one I explained in the video.

Would be great to hollow out an existing CDI and revise this custom CDI board into it. That would make it easier to mount on the bike. One question though. How do i know if my bike is AC or DC? My bike has a 4T engine.

[@MrWolfDiy]

Greetings friend, It's a good idea, but the space inside the boxes is usually very small, because SMD components are used,And it is of low quality. If you've seen my previous videos, I showed that in many cases they fill the inside with sand, so that less resin glue is used.I've already made a full video on how to identify the type of CDI. However, Tell me the name and model of your motorcycle and I'll tell you.

[@MrRacerhacker]

Do get some bigger CDI boxes but worst case easy to make a box for it

@@MrWolfDiy in my country there's regulations for CDI's to be original. Now if the original housing could be reused including the connector then an unrestricted CDI won't be detected by the inspection inspector. I'm driving a Piaggio zip. We have 3 types of CDI's available. One restricted to 25kmh, 45kmh and one that is technically illegal because it's unrestricted. For reference it's dutch regulations.

@@MrRacerhacker that isn't my goal. It's to mask an unrestricted CDI from the law.

[@rodhelgabon3534]

Good day sir,this is it what you said to me,is it suitable for my honda tmx 155?

[@MrWolfDiy]

Greetings,Yes it will.🙏

[@rodhelgabon3534]

Thank you sir,i will try to make it if i can buy the needed parts,can you sent me the diagram.again thank you so much of yor kindness,keep up the good work.God Bless

[@mohammadashfaq6134]

Can i use in carburetor car

[@MrWolfDiy]

No, It's for motorcycles, 🙏

[@Ashishgaming-f3g]

Make a MK 12 engine cid

[@MrWolfDiy]

If your engine is of the old type with a breaker point ignition system, significant changes are required, such as removing the old ignition system and using a crankshaft position sensor or a Hall effect sensor to operate the CDI (Capacitive Discharge Ignition), and precisely adjusting its timing. However, in some newer models, the ignition system is already CDI-based, allowing you to use the existing CDI or any other CDI ignition system.

[@andrewsun4881]

Hi friend, What is the purpose for the thermistor? Thanks

[@MrWolfDiy]

Hi, 1. Protection of the Thyristor: If the CDI circuit operates at high temperatures, the thyristor may overheat. The thermistor can regulate the current path by changing its resistance when the temperature rises excessively, preventing damage to the thyristor. 2. Controlling the Gate Current According to Temperature and Adjusting Ignition Timing.

[@andrewsun4881]

@@MrWolfDiy Thanks for your sharing. In my thought, the ignition timing is controlled directly by the metal tab on the outer radius of the rotor. Is it also adjusted by the CDI circuit ? To be honest, I'm not familiar to the circuit design. Could you explain more. Appreciate.

[@Savage-lx5yj]

It appears timing is controlled by trigger or pulse generator.

[@ILF69.]

socket diagram?

[@MrWolfDiy]

Which socket ⁉️

[@ILF69.]

when you gonna plug it to the bike cdi socket

[@MrWolfDiy]

Hello again, My motorcycle socket is a 6 pin AC CDI socket, I have already explained the complete CDI wiring diagram in the video, you can also search on Google for "6 pin cdi wiring diagram".

[@ILF69.]

can i use 10k thermistor mf2at?

[@MrWolfDiy]

Hi, Test it. "If" the spark is weak or delayed, reduce the value, and for the D5 diode, use a 1N5408 diode.

[@AssasinAssuria-bv3zn]

Бұл коммутатордың әдеттегі стандарт коммутатордан айырмашылығы, үстемдігі жақсы жағы неде ? Бұл қандай жақсы параметрге ие ?!

[@MrWolfDiy]

This is a suitable replacement for the factory versions and, modified to give you a stronger and more consistent spark.

[@mdrafiqul3358]

[@ILF69.]

all AC bike?

[@MrWolfDiy]

Yes Single cylinder bike with AC stator

[@pranavhb1716]

More power + less fuel = heat Heat = ur block and piston turning into molten metal

[@MrWolfDiy]

hi Everything has a standard limit. Even this CDI. I previously had a Denso CDI unit whose spark power was ten times stronger than my current module-it was the factory version. I sold it for $300. However, it didn’t cause any issues. Overheating in a motorcycle due to the ignition system is caused by irregular sparking, not excessive power

[@ravijayasundara-eu9gf]

My Honda cg125 got 6v breaker point ignition (6v breaker points magneto ignition)..together with mechanical advancer unit.. Primary ignition coil mounted behind the flywheel and getting earth through breaker points. I just want to give Primary coils earth through a power transistor (from Collecter to Emiter) while Base pin of the transistor triggering through breaker points. Basic 2nd generation ignition system like that...... But I am unable to design/ figure out this.. Dear Wolf can you please make a solution for that.. Please please, thank you..

[@MrWolfDiy]

Greetings This method is possible but requires skill... To convert the 6V breaker point ignition system of a Honda CG125 to a transistorized ignition system, follow these steps: you need some components, 1. NPN power transistor such as 2N3055 or TIP41C 2. 1kΩ resistor (1/4W) 3. Freewheeling diode (1N4007 or 1N5408) Wiring Instructions: 1. Connecting the Transistor to the Ignition Coil: Connect the Collector (C) of the transistor to one terminal of the primary ignition coil (the other terminal of the coil remains connected to 6V positive). Connect the Emitter (E) of the transistor directly to ground (chassis). 2. Connecting the Breaker Points to the Transistor's Base: Place a 1kΩ resistor between the breaker points and the Base (B) of the transistor. Connect the breaker points directly to ground (chassis). 3. Freewheeling Diode for Transistor Protection: Install a 1N4007 diode in parallel with the ignition coil, Cathode (white stripe) to 6V Anode (plain end) to the transistor’s Collector. How the Circuit Works: _When the breaker points are closed: The transistor turns ON, allowing current to flow through the ignition coil. A magnetic field builds up in the coil. _When the breaker points open: The transistor turns OFF, cutting current to the coil. The collapsing magnetic field in the coil generates a high-voltage spark at the spark plug.

[@ravijayasundara-eu9gf]

Many thanks for your great advice. You got the point. I will try this soon to enhance the spark capacity. Hope this will work. Present spark of the bike is very low. I just want to convert this into CDI but worrying about the advance angle variations.... Dear Mr Wolf you explained this in to the right point. Very helpful to all of us.. appreciate heavily.. Thank you again. Peace..❤​@@MrWolfDiy

[@josedomijan1068]

never a schematic circuit??? you are a chiseler

[@MrWolfDiy]

Dear friend, this circuit does not have a schematic. I have reverse-engineered an OEM CDI before and made modifications to increase its power. Circuits that have schematics will be provided.

[@djieffe]

this is bullshit, does nor work cz still one spark in cylinder.

[@MrWolfDiy]

This circuit is completely correct, and according to the video it works correctly, probably you either didn't try it, or didn't execute it correctly. Explain the problem in more detail so we can see where the problem is...

[@djieffe]

@@MrWolfDiy the chemical principle, it can't improve combustion unless you have a bad spark. to improve combustion a tinny bit you must add sparkplugs.

[@djieffe]

@@MrWolfDiy so improving the spark "quality" is useless.

[@jubajub9965]

Are u stupid ? The more electricity through the spark plug, the higher air fuel mix burns, so it would be 100 % complete combustion and no Unburned fuel .
