Sounds pretty good bro! On my phone at least, it sounds like a dirt bike & not like the typical motorised bike engine exhaust note I'm use to! That's a good thing!
That’s with the silencer on it. Without it it’s really loud. Like, I usually run without a silencer. Not on this bike. She’s to darn loud for me lol. I’ll have to make a video without the silencer for fun sometime soon.
I have a question about a 50cc cylinder. I just recently ruined my 47mm engine and had to use this 40mm one. The new cylinder came with no open transports so I opened them up like my 47mm cylinder was. Was this a bad thing to do. was wondering because I cannot get the engine to run
Can u use a coil off of a 2stroke snow blower as a cdi to get spark since my cdi is fried outin order to get spark or what can i use to get spark to start since i don't have any money to order a new cdi box
Hello my name is Robert from Colorado Springs I was wondering would it be possible to have an electric push button to start a 100 cc 2stroke motorized bicycle if so could you possibly make a video on it thank you
ATV I think ac , cdi red& black going to the inside corner of the 4pin plug? is this powering the coil. { Or power coming in from the stator] ? power in is normally in to the first of the two pin . on mine is brown . could this be red 7 black in & out red & black to the coiled ? blow & whit is pickup that the same . ? can you help ?.
Great video very helpful the cdi that comes with the engine sucks is this cdi a better cdi how can I make my cdi an magneto last longer the HP magneto and cdi an magneto a good set up I tried another motor too see if it would fire it did not fire could you please help me how often do you see look at these comments thank you
I need help wiring a Chinese 5 wire ac cdi to my bike. The colors are red, blue, yellow, black and green. The coil has a 2color coded prongs coming out of it. A green and a black comeo out of the coil. I know with most Chinese the green is ground. So my question is do I run the green to my magneto and the coil? I'm assuming that the black will go to the coil since it's color coded. The red to the red from my magneto. But then that leaves my a loose blue and yellow
I need to extend the wire length from my CDI to the engine and the length of the kit throttle to the CDI. I'm installing a mini bike seat on my bike and installing the CDI under the seat. What is the typical wire gauge on a two stroke engine? What is the wire gauge on the typical kit throttle? Thanks much!
Can I somehow connect this motorized bike CDI to a 125cc pit bike and use it as a spark generator? Because I bought a bike without the spark transformer.
GuitarJoe I would recommend trying to find the original equipment for the bike. If it is a 4 stroke engine then it’s a completely different ignition system. If it’s a newer style two stroke then it’s going to need a cdi unit that has a built in trigger wire in the cdi. These CDI’s for motorized bicycles do not use a trigger. The rotor that turns between the magneto is what created the charge that goes to the coil.
It really depends on your setup. It mostly is noticeable under boost from a good pipe as the ignition curve helps add more power through the rpm range vs a stock box ignition
Hay i have had bad luck with cdi's i have ordered 2 different ones from 2 different companies and as soon as i got them i test with volt meter and nothing i hook them up anyways and still nothing tell the companies and they send me new ones and the same thing neither one registers on volt meter nor works on my bike how likely is it to get 4 cdi's mailed and all 4 are bad 2 are black box cdi and other 2 are bbr tunning volt master stage 1 cdi's. Its been 3 months since i ridden my bike what can i do or is there other cdi's that can work with a 49cc bike kit. I need help please.
If it runs the way it is right now then probably not. Only when you start really amping up the high compression does it need to have stronger spark and ignition.
Good video, very informative. Thanks. What's your opinion on "boost bottles"? I have seen pro and con for them, but every pro video actually shows the bottle in action. Thunderhead 289 actually pinches off the tube to show the difference, and it made the motor run smoother with the bottle active. In most cases it seems to produce a smoother sounding motor and the claim is for more power at some point in the power band. The nay sayers so far have not done anything demonstrative to prove their point, so I'm of the opinion that they work. Also, do you think that an expansion chamber exhaust requires re-jetting, or maybe adjusting the clip on the needle? I bought the F2 Thrust pipe from bikeberry and it was causing the motor to four stroke when coming off the throttle at speed. I raised the clip one notch, and it quieted it right down. Much smoother now.
Hey Eric, from the research Iv done into understanding a boost bottle and other forms or volume intake type things. In most cases they are on 4 strokes and have a resonance effect that helps the low end torque of the said engine. you wouldn't believe it but if you pop the hood on a new 2000+s Honda car and look at the intake you will see a large style box with a auxilary box for just extra volume. that is a form of boost bottle that I'm referring to in a 4 stroke. For a two stroke the only engine that I can think of that uses anything Like a boost bottle is the yamaha banshee with the twin carb setup and the balance tube that goes between both carbs. other than that I havent seen it in use in any other production motorcycles. For our engines though I would highly doubt it gives you any kind of gains at all other than a place to catch a air leak and end up destroying your engine from running lean. I re jet my engine if it even feels colder outside. jetting changes with the weather. pressure can even change your jetting. That pipe your talking about is a real choked off pipe and so it loads the engine up a bit, thats why it four strokes. Hope these help man.
@@wtmotobikes8838 Thanks for your response, I'm kind of new to the two cycle ICE. The way that I had envisioned the boost bottle was as a sort of cushion. The air flow entering the motor at idle and at speed, has mass and inertia. The cycle pulsations of the combustion/exhaust/intake process interrupt the constant flow of the air/fuel mixture. The bottle relieves the momentary back pressure of the flow when the cycle pulses occur, instead of it pulsing back into the venturi and disturbing the mixing event. That's the only idea that makes any sense to me. Sort of like an expansion chamber on the intake side. My other issue was that the motor does not come with any kind of owner/instruction manual. You buy a motorcycle, it tells you what kind of spark plug, and the proper gap. I have seen two videos on this matter. The first recommends .025" gap; the second video recommends .035. There has to be a way to find which gap between those two extremes works best. A sort of rule of thumb, as we used to say. If this, than do that...
@the guy nobody likes I did, couldn't get the motor to idle. Took it off. It was a CDH Power product, had a bottle made out of a used CO2 cartridge. Not even close to 66cc displacement. They call it a "Function Bottle". I suspect that it's supposed to be replaced with an NO2 setup. No idea, checked it for leaks, there weren't any. I have a bottle I've adapted for use that is a lot closer to 66cc's I'm going to try that once the hideous weather here moderates somewhat. Rain, hail, snow, windy as hell; cold as a nun's bun. And that was just today!
hi, I wonder if you can shed any light on this, WT or anyone? I Have recently brought a pw80 CDI and a stand alone coil, also for a pw80, I have 2 separate black wires so one's gonna be a ground connected to the magneto loop set and the other black will connect to the terminal on the coil. connect orange to the other terminal which is posistive. but I'm getting nothing at all.. I also have a red and white wire that I'm not sure what that does.. but both brand new today and wired as you did in your video and nothing is happening . No spark whatsoever.. I'm confused. It starting to do my head in, I've walked away from it for a while but found myself re watching this video again to double check.. and confirmed I did everything the same.. what could it be . And what does that red and white wire do. The 2 blacks for the killswitch have a plug on I presume they do not need to be grounded out or anything ? Oh my days .. help it's driving me crazy here.. :/ Cheers Sy
Does your pw80 cdi have 5 wires or 6? Also does it have a Mitsubishi symbol on it or no? The older Mitsubishi style cdi work with a AC current system aka magnet and magneto. The newer style system need a timing magnet for trigger and a DC battery as well. Please confirm which cdi you have to help with the question.
@@wtmotobikes8838 5 wires and 2 black kill switch wires like the ones you cut off in your video. no mitsubishi type symbol or any type of symbol, just a plain box, does that mean its the wrong type? Both were off eBay.
If it doesn’t have the Mitsubishi symbol on it it’s probably not the right one. Iv always had to pay $50-$110 for the old Mitsubishi style ones for magneto because they don’t make them anymore. I’ll see if I can find you a link to one.
Can you make another video that uses the CONTROL UNIT IGNITION CDI BOX YAMAHA PY50 PW50 PEEWEE 50 PIT PRO TRAIL DIRT BIKE. Because this is the only one that is on the market in my region. And explain how to put everything together because my electrical system is becoming weaker by the days
The correct CDI will have a Mitsubishi emblem on the front side of it. If it is the cheap ones on eBay or Amazon they will need a 12v battery and a magnetic trigger to operate. There is a guy who I did see who managed to make a trigger style ignition work for him. I haven’t done it myself though. I could try though.
@@wtmotobikes8838 interesting. I figured it would take much more voltage to burn a wire. I try to shut the fuel valve off and ride for 30 more seconds. It'll drain the float bowl and shut off on it's own, and then it won't reek of gas inside my apartment (as much).
@@ThunderFoxMusic I've heard that's a bad habit. Like all things, for every person that recommends something there is another one telling you why it's wrong.
if you go on ebay you can look them up as a pw80 cdi. the newer ones that cost 10-25 bucks all need a magnetic pickup on a rotor and a 12v battery to run them. the older style 83-99' used the AC currrent from a magneto and magnet rotor. they usually look dirty and are priced higher at 50-90 dollars typically
It's dangerous to run anything without a Killswitch you never know when the throttle is gonna hang wide open or something else could happen and you have to shut the engine down. That's my opinion on that.
I love u man, because of u now I know there are 2 types of CDIs!
Well Done dude, sounds decent. 💪🏁👍👌✌️

I can't get my engine started ( bad CDI box) can the CDI box be substituted
Holy shit!!! For real? What cc? 80? Any mods? Jet? Hp head? Piston skirted,ported and polished?

Watch my most recent video and watch the powerband hits on WOT pulls. That cdi loves pipe boost.

U not too smart u clown
My motorized not working with this det same CDI from scooter ?
I'm actually gonna wire 2 stock cdis in succession. Twice the spark
I prefer to also turn off the motor by using the choke instead of using the killswitch
I have an mz65 pipe on my gasbike.com 100cc raw racer 3 engine. Does it need a better cdi and ignition coil
If it runs the way it is right now then probably not. Only when you start really amping up the high compression does it need to have stronger spark and ignition.

Thunder Fox it makes the magneto last longer. When you ground the circuit into the magneto it burns the ground wire of the magneto.
