Omg, thank you so much for making this video! It was SO helpful in my learning about CDI's and testing mine to see if it was the cause of my scooter issues. Thank you!!! 😁🙏
Thank you for watching my video
Your channel has saved me so much $ on my scooter ty so much
That was my goal when I started this channel to help people and save them lots of money . Thank you for watching my videos and happy holidays
Wow 🤩 I really appreciate you explained the CDI so good in detail. It really helped me out to figure out what was going on with my motorcycle! New Subscriber! 👍😎🤘
Thank you for watching my video
You locking great man i placed the blue cdi on my icebear vision 50cc 2022 with the orange spark plug cable because it didn't start with the black cable so my scooter just got more power in accelerating. I like it more with the blue cdi works great
Hello my friend thank you for watching my video
Thanks for the imfo my friend!
Hello my friend thank you for watching my video
I had a rough idle but driving seemed fine and was wondering if maybe my CDI was bad. This continuity test proved that is was fine. Thanks for helping me rule out one possibility!
Sometimes cdi under stress do not work perfectly even if with the continuity test look fine also try to replace the spark plug that could be why you have a rough idle 👍
@VirberelloScooterTips I already replaced the spark plug and also tested the ohms of the spark plug wire and it was above 7.500 ohm reading or so, replaced it with a new one, will see how it runs today.
Ok so after 30-45 minutes of driving around, the idle gets rough. It seems like the idle is "okay" until after a while, but I had to turn up the idle pretty high so it will not stall and the back wheel is spinning because the idle is too high. I tried spraying carb cleaner to find a vacuum leak, could not find one. Changed spark plug and the wire. cleaned out the air filter. My next guess was CDI but it was fine on the volt meter. I am going to order a new fuel filter, drain the gas and make sure the tank is clear of debris and replace the filter next. It has almost 32,000 miles. Maybe the engine is just getting old? It is a 2016 SYM HD200 EVO. (fuel injection, not carburetor)
wow 32k is a great mileage that can also be a valve clearance or worn out piston rings check the motor pressure to make sure but if that happen after 30 to 45 minutes you could have the valve spring little tire / worn
@@VirberelloScooterTips Well I found the problem after changing my spark plug wire, furl filter, petcock, testing cdi, new spark plug, valve adjustment and the list goes on. The spring had ripped through one of the clutch shoes on my clutch! I replaced the clutch shoe assembly and the bike runs great again! haha! No random rough idling and the back tire does not spin when ont he center stand anymore lol.
I just got one and installed it and it actually lowered my mph by like 5mph if I where u stay with the oem one
Sometimes that can happen because we are dealing with with low cost part from China for me I always prefer the Oem 👍
Thank you!!
You are very welcome 👍
Please help I put in the blue CDI but it still limits my revs it refuses to redline it did increase my speed by 6-7mph but I'm still stuck at it never reaching the red line at all would it be better if I use the original and remove the rev limiter?
I’m trying to get my daughters gokart going, NO SPARK.
Just replaced stator which I thought it was that, still no spark.
Wires are all good, fixed them, retape them.
Have cheap multimeter, doesn’t beep, old multimeter messed up(it beeped/other settings)
Checked the cdi and show some readings on ground, checked rectifier and same.
Have zero clue what I’m doing wrong
I’m not an electrical guy😩
It sounds like you've been working hard to diagnose the issue with your daughter's go-kart. Here are a few steps you can take to further troubleshoot the no spark problem:
Check the Spark Plug:
Ensure the spark plug is in good condition. Remove it, clean it, and inspect it for any signs of damage. You can also try replacing it with a new one if you're unsure.
Verify the Kill Switch:
Make sure the kill switch is not engaged. Sometimes the kill switch can be faulty or accidentally turned on, preventing the spark.
Inspect the Ignition Coil:
The ignition coil is responsible for generating the spark. Use your multimeter to check the resistance of the ignition coil. Refer to the go-kart's manual for the correct resistance values. If the readings are off, the coil might be faulty.
Check All Connections:
Ensure all electrical connections are secure and free of corrosion. Loose or corroded connections can prevent the ignition system from working properly.
Test the CDI Unit:
The CDI (Capacitor Discharge Ignition) unit is another critical component. If possible, test it using a known good unit. There isn't always a straightforward way to test a CDI without specialized equipment, so swapping it with a working one can help determine if it's the issue.
Verify the Ground Connections:
Good ground connections are essential for the ignition system to work. Make sure all grounding points are clean and secure.
Check for Broken or Damaged Wires:
Even though you've retaped the wires, double-check for any broken or damaged wires that might have been missed.
Consult the Go-Kart's Manual:
If you have the go-kart's manual, refer to it for specific troubleshooting steps and electrical diagrams. This can provide valuable information on what readings to expect and where to test.
Use a Known Good Multimeter:
Since your current multimeter is cheap and the old one is messed up, consider borrowing or purchasing a reliable multimeter to ensure accurate readings.
If you're still having trouble, it might be helpful to seek assistance from a friend who has more experience with small engines and electrical systems or take the go-kart to a professional mechanic for a thorough diagnosis. I hope this can help you

Previous owner replaced the ignition switch, took the lights off, etc.
It’s a “fun kart 150cc” gy6 motor.
Gona go buy new plug in bit, south texas been raining on and off….
I checked the cdi and rectifier like your vid shows…
Idk I feel like ima have to rip over the wire harness and go from there….
Thank you for your help🙏🙏
Thank you for thr valuable information. I think my CDI might be bad and wasn't sure how to check. I'll try agin tomorrow and see how it goes.....

Question ? I am working on my son's 2007 Ricardo znen. What kind of cdi box ? Has the longer one in it but he had a neighbor work with it so not sure if this neighbor changed anything up ?
It can be difficult to determine the exact type of CDI box required for a specific scooter model without additional information. However, as the 2007 Ricardo Znen likely has a GY6 engine, a common CDI box used for this engine is the DC-CDI box.

I've purchased one of the blue aluminum cdi. But didn't install noticed it only had 5 pins. Can you explain the difference it 5 and 6 pins.
The difference between CDIs (Capacitor Discharge Ignition) with 5 pins and those with 6 pins lies in their functionality and compatibility with different ignition systems. Here's a breakdown of the key distinctions:
5-Pin CDI: This type of CDI is commonly found in older motorcycles or vehicles with simpler ignition systems. It typically includes the following pins:
a. Power Input: Connects to the ignition switch or the battery's positive terminal to provide power to the CDI.
b. Ground: Connects to the vehicle's ground or negative terminal.
c. Trigger/Pulse: Receives a signal from the engine's ignition coil or pickup coil to trigger the CDI's firing sequence.
d. Ignition Coil Output: Connects to the ignition coil, which generates the high voltage required for spark plug ignition.
e. Kill Switch/Engine Stop: Connects to the kill switch or engine stop button, allowing you to cut off the engine's ignition.
6-Pin CDI: This type of CDI is commonly found in newer motorcycles or vehicles with more advanced ignition systems. It includes the pins mentioned for the 5-pin CDI, plus an additional pin for enhanced functionality. The pins on a 6-pin CDI are typically configured as follows:
a. Power Input: Connects to the ignition switch or the battery's positive terminal.
b. Ground: Connects to the vehicle's ground or negative terminal.
c. Trigger/Pulse: Receives a signal from the engine's ignition coil or pickup coil.
d. Ignition Coil Output: Connects to the ignition coil for spark plug ignition.
e. Kill Switch/Engine Stop: Connects to the kill switch or engine stop button.
f. Rev Limiter/Speed Limiter: This additional pin allows the CDI to control the engine's maximum RPM or speed, limiting it within a specific range for safety or performance purposes.
The presence of the sixth pin in a 6-pin CDI enables additional features such as a rev limiter or speed limiter, which are not typically found in 5-pin CDIs. If your vehicle originally had a 6-pin CDI and you have purchased a 5-pin CDI, it may not be fully compatible with your ignition system, potentially limiting certain functionalities or causing compatibility issues.
It is crucial to ensure that the CDI you purchase matches the specifications and pin configuration required for your specific vehicle or engine model to ensure proper functioning and compatibility.
Hello. I got a guestion. I have a dc cdi (kymco) and when i use the black probe on the ground in the left corner in the bottom and the red probe on the top right, should it have continouity? It does with mine but shouldn't that be normal because they are both ground.
Thank you for your reply in advance.
Greetings from Holland.
Hello yes that is normal 👍
@@VirberelloScooterTips Ah ok. Thank you.
I don't have a multimeter tester. My 3v DC continuity tester is lighting up when I touch the ground pin to +AC CDI power pin. Can I assume my CDI is bad or do I need to re-test with a multimeter?
When troubleshooting the CDI (Capacitor Discharge Ignition) system on your gas scooter, using a 3V DC continuity tester can give some initial insights, but it may not provide the complete picture. Here are some key points to consider and steps to follow:
Understanding Your Continuity Tester Reading
DC Continuity Tester Limitation:
A 3V DC continuity tester is designed to check for electrical continuity, not for measuring voltage or diagnosing AC systems accurately.
When your tester lights up upon touching the ground pin to the +AC CDI power pin, it might indicate a circuit path, but it doesn't tell you if the CDI is functioning properly.
CDI Function:
The CDI unit operates with AC voltage from the stator. It's crucial to ensure that the input voltage and signals are correct.
Misinterpreting DC continuity can lead to incorrect conclusions about CDI health.
Steps to Properly Diagnose CDI Without a Multimeter
Check Connections and Wiring:
Inspect all connectors and wiring for signs of wear, corrosion, or damage.
Ensure that all connections are tight and secure.
Visual Inspection:
Look for any obvious signs of damage or burning on the CDI unit itself.
Check for any loose or broken pins in the CDI connectors.
Test the Stator and Pickup Coil:
Use a continuity tester to ensure that the stator and pickup coil are not open-circuited. However, remember that this will not verify the correct AC voltage output.
Substitute CDI:
If you have access to a known-good CDI unit, you can swap it out and see if the problem is resolved. This can be a practical way to test if the CDI is faulty without specialized tools.
Why a Multimeter is Recommended
AC Voltage Measurement:
To accurately test the CDI, you need to measure the AC voltage coming from the stator. A multimeter is necessary for this purpose.
The CDI typically requires specific AC voltage levels to operate correctly. Measuring these voltages with a multimeter will give you a clearer picture.
Resistance Tests:
A multimeter can measure the resistance of the stator and pickup coil windings, ensuring they are within specification.
Detailed Diagnostics:
Some CDI units can also be tested for proper output using a multimeter, which might involve checking for spark strength and timing.
Conclusion
While your 3V DC continuity tester provides some initial information, it is not sufficient for a thorough diagnosis of the CDI system. To accurately determine if your CDI is bad, you should:
Acquire a Multimeter:
Invest in a basic multimeter that can measure both AC voltage and resistance. It's a valuable tool for various electrical diagnostics on your scooter.
Retest with a Multimeter:
Measure the AC voltage from the stator.
Check the resistance of the stator and pickup coil.
Verify the CDI output according to the scooter’s service manual specifications.
By using a multimeter, you can make a more accurate diagnosis and avoid unnecessary parts replacement.
i have an adjustable cdi and the screw adjusts idling rpm
Hello my friend thank you for watching my video
How do you test the kill switch?
Hello Key man to test the kill switch wires on a gas scooter, you will need a multimeter, which is a tool that measures electrical current. Here are the steps to test the kill switch wires:
Disconnect the kill switch wires from the rest of the scooter's wiring harness.
Set your multimeter to measure resistance (ohms).
Touch the probes of the multimeter to the two wires that were connected to the kill switch. The multimeter should read a very low resistance (close to zero ohms) when the switch is in the "on" position, and a very high resistance (infinite ohms) when the switch is in the "off" position.
Activate the kill switch by pushing it to the "off" position and test the resistance again. The multimeter should now read a very high resistance (infinite ohms).
Release the kill switch and test the resistance again. The multimeter should return to a very low resistance (close to zero ohms).
If the multimeter readings do not match these specifications, there may be a problem with the kill switch wires or the switch itself, and further testing or repairs may be necessary.
OMG: $199 for oem ci dc... can u tell me if 1 these dc cdi replace mine ? its a 2000 savage ls650p
Wow $199 is lots of money I'm not sure if you can place a scooter cdi on a savage 650 but I can tell you that this cdi are not to reliable
Hi I'm new to the utube channel I hope this will get to you.
I have a 2021 amigo ss 150cc.
It's so hard to start cold that it kills battery trying when I'm jumping it from a car it takes me holding the start button for long periods and it eventually starts it's hard to keep going but once warmed up it runs great. What are some trouble shooting tips. I would really like to talk on phone if possible. I'm desperate I've missed a week of work already. Please help.
Hello my friend There could be several reasons why your gas scooter is not starting. Here are some common reasons:
Faulty spark plug: A faulty spark plug can prevent the engine from starting. Check the spark plug to see if it is dirty, corroded or worn out. If so, replace it with a new one.
Clogged air filter: A clogged air filter can restrict air flow to the engine, causing it to not start. Check the air filter and clean or replace it if necessary.
Dirty carburetor: A dirty carburetor can also prevent the engine from starting. Try cleaning the carburetor or taking it to a professional mechanic to get it cleaned.
or you need to check motor compression and do a valves clearance service
Thank you for watching my video
Thank you I I got it going. It was multiple things. Basically I changed all ignition parts. And bought a new duralast battery. My scooter had 12 miles when I bought it. It now has close to 8,000. And I out run the expensive scooters. Chinese scooters are Ok in my book. Thx again for all your videos. And watch for me because I definitely gonna support your channel.
What if there is a spark, but it still has problems starting
Hi if you have spark but you have problems I will check the valve clearance and the compression 👍
Hello
My blinkers dont work,is it possible the cause is cdi box change?
Already changed regulator.
And blinkers indicators doesnt work.🤯😇
Did you change the blinker relay ?

Can this cause your bike to have 50% power ?
No I don’t believe so I think you need to replace the roller weight inside the variator but is not easy to pin point the problem if I don’t see the scooter
My scooter uses an AC CDI, so I bought the blue one and it doesn't start, but when I plug in the old one it starts perfectly. Why you think this happens?
The blue one uses DC current. You would need one that supports AC voltage
I have the blue AC cdi on my scooter for the last 5 years and is running great but sometimes few cdi are shipped already defective from the factory
