This was a lot of fun to compare the two engines back to back on the same bike and in the same video. Look for more Phantom 85 content on this channel in the future.

Amazing video , I loved watching this
oh cool stuff man. love that guy. happy you get to work with him. good luck with that bad boy.
Thanks man. I'm glad you enjoyed the video.
I can tell you how to get the most out of that stock yd 100. You will need a 32 tooth sprocket. You will need a miniature drillbit set(harbor freight) to drill out the main jet the very next drill size up(very small increment) then take out the filter and filter screen. Reassemble the airbox cover with a nut spacer sandwiched in between carbeurator and red airbox cover, this will create a ram air intake with no air restriction at top speed. Then adjust throttle needle to best top speed setting without running too lean. Knocking is a sign of lean condition. When you get it dialed in the bike will have noticeable more acceleration and much more top speed. This set up is more cruiser and pavement gearing
We don't need no stinking air filter...polish that engine with dusty air...
Open that throttle! 60? Lol. Thanks for the ride.
I got scared at 45MPH and it still had some left in it. lol
Good video thanks from England
Sadly the YD100 exhaust port can't be bored out nearly as big as the Phantom 85 due to it's common 40mm wide bolt hole pattern....I'm curious how much power the Phantom85 would lose, just by making it's exhaust port smaller, down to the same size as a YD100 port & stock pipe ID.
Thanks for video iv got yd100 were can i buy phantom 85cc from
Hello i have a new 65cc build from bike berry. When i go slow speeds the bike feels like it wants to stall. Is this normal?
I think it's probably a combination of things, your only 140lbs and LA is like 220lbs that's a big difference for noticable acceleration. I also think you got a real basic yd100 so to speak cause most yd100's I've had. The 85 comes with a 36t sprocket from factory so you know in case you wanted to know. As far as vibration I would check the mount. Release the rear mount completely and if the motor separates from the seat post tube that is most likely your vibration. Just reattach the motor but make sure the front U bolt is not pulling down on the frame and motor which is what causes the vibration do to extra stress. If you get it centered and I. Correct the vibration ( well most) should go away.
Thank you , this helped me alot
16:53 i noticed that rear tire looks like it is got some bad dry rotting rubber, keep an eye on it. Or just change it out. Thanks for the ride and stay safe!
Are those both motors us only?
Great vid Bud, you have a humble realistic approach to testing out these engines. Keep it up with great content.
JM Rides
Thanks, will do!
A proper tune pipe for any two-stroke makes it peppier. I have a experimental 100 cc and I have made all the difference. I also have an 80 cc here as well
When u were riding the YD, why was it whining or whirring chirping like that? Is it the clutch? Mine does that ever since I put the exhaust back on it and I'm not sure (cause I was riding it without an exhaust for a little while, (it fell off cause of vibrations, lmao) and it seems like once an exhaust was back on it, the engine was quiet enough that I could hear that sound). Not sure what the problem is.
It's made that noise since new. I think I just got a lemon with a noisy clutch.
So you did a video a few years back about wiring a motorized bicycle and putting a regular rectifier and some other things on it to help charge the battery and keep things running My question is back when you did the video the second part of that or another part of that video you came back and said that the pink wire on the regular rectifier needed to be grounded to the frame is that correct
By the way here's the other video talking about.
ruclips.net/video/FyqMZhsZvUg/видео.html
Looks like youtube pulled your URL. In any case, turns out the generator peaked around 12V and was actually designed for use directly with 6V incandescent bulbs. So, that being said, it couldn't put out enough voltage to charge the battery as the rectifier needs to have around 14.5V on the input side. Hope this info helps.
Yeah that helps some I went ahead and wired it in and so far I have a 12 volt headlight and a 12 volt horn I have it installed any other lights yet though other than that so far it's keeping charge of the 12 volt battery so what you're saying is is it the lights need to be less than 12 volt
Can anybody help. I purchased a 2 stroke bicycle engine but the intake manifold hole is located on the crankshaft case???
Lucky! that is ok. Intake manifold in crankshaft allows for more air/fuel mixture to be pulled in as piston is not in the way. It is actually preferable to cylinder fed intakes.
I have bought and used a couple of v3 phantom 85's and find the 1st issue if the lock washers suck and the cdi screws come loose. These need to be changed immediately out of the box
Phantom or minarelli vertical cylinder? Dude i dont know what to chosse
Good luck! This will be a nice long term test. Sorry again about the lazy shipping, I definitely should have packed it better lol...
Run it till it blows up! Just be careful, that motor can kill budget bikes.
Side note: Because it has the DLH Performance balanced crank, if the piston or cylinder fails you can drop on a new one with no modifications.
I'll keep that in mind. Thanks for sending the engine way. I'm looking forward to see how it holds up. So far, so good.
Keep at it man! It takes alot to put yourself out there but as you learn you grow, keep at it!
what is the cost per cell
I have the yd100 on my spare bike and the phantom 85 V3 on my main bike and I love the phantom! I already got a different reed valve and a bigger carburetor I'm just waiting for them to make a nice expansion chamber and it should really open it up even more. I'm thinking about adding a reed valve and bigger carburetor on the yd100. They sell a nice dio reed kit for it
@westhelockpicker3615.. Hello, I was considering buying a YD100 myself and doing the same (installing a reed valve and carburetor kit). So my question is do you need to also install a windowed piston when using a reed valve? Does the YD 100 already have a windowed piston installed at the factory? And last question - what would be the best exhaust pipe for the YD100 to increase power/performance?
@@90daysinvegas53 no it doesn't come with a windowed piston but if you buy the dio reed kit for it then it comes with everything you need
@@Westhelockpicker Does the Dio reed kit come with a windowed piston? Do you need a windowed piston when using a reed valve? And what kind of exhaust pipe would be best to increase performance for the YD100?
@@90daysinvegas53 yes it comes with a windowed piston that's why I said it comes with everything you need and yes the windowed piston and reed valve work together and as for the exhaust it depends on who you ask. Watch some videos and learn for yourself
Just getting done with the break in period on my phantom, next up is up jetting the carb. I need to make more vids of my bike, Love that thing the phantom is wo a doubt BADAZZ💪🏼💪🏼
Excellent
I've got a bbr I have a bbr tuning stage 4 66/80 cc when I had the 44 tooth sprocket I was able to get 46 mph slight downhill. I had the stock NT carburetor PROPERLY ADJUSTED AND JETTED. I use the banana-shaped expansion chamber. I have no idea what my top end is with the 40 tooth sprocket I have now. 89 octane with 5 oz synthetic oil per gallon. Remember the smaller the engine the more touchy it is on weather change as far as tuning.
pulsar i have memories of that frame the rear wheel hook up is dangerous without motors power be careful with adding power the wheel slots are not welded their only crimped . stay safe im testing the new phantom 85 v3
Where is the video where you crashed it?
Nice motor
That's why yd100 has some serious problems going on. You can't hear that loud chirping coming from your motor?
Yes, I'm aware of the sound. It's been like that out of the box. Many commenters have suggested it's the clutch, but I don't care to fix it until its broken.
My 100cc stock unbranded is so much faster than that YD 100. I am not saying anything bad but I'm in break in period only using between 1/4 of my throttle and a little over so I gave it proper break in, it was doing 18mph - 20mph. It isn't fully broken in yet so I am curious to how fast it will go once it is fully broken in. My 100cc haves all the same specs as the YD 100 it's just not called the YD 100 . It has the 50mm piston, the Bofeng performance carburetor, the one piece jug and head, the red and black upgraded coil pack, Z4C spark plug, 50mm x 2mm piston rings, 36 tooth sprocket, and I put it on a Diamond Back Wildwood 21"XL bike. She is full of torque and power, I even took it up a very steep hill and it handled it and like I said not even at half throttle. I am running a 3.2oz oil to 1 gallon of gas ratio because Hughes motorized motors said to run that from start to death, and I am trusting him on that as he knows a ton about these engines
I ordered the kit off walmart.com Anqidi was the seller and I swear it's a YD 100 and all pasts I ordered for it to change out after break in are YD 100 parts and they fit because I put them on to make sure and then took them off till after she is broken in all the way.
The kit did say modified set and also high performance. Maybe that's why it's so good? IDK because it is my first build and I love how fun it is and it's definitely a hobby now for sure.😃
I subscribed to you because I love anything that has to do with Bicycle engines and all the bike builders deserve a chance. Great video bud.💪💯👍
Oh also I would like to add that you was using stale gas in the YD100 !! You admitted that when you couldn't get the cap open on the gas tank. You said it's not been open in a while. Then you put fresh gas and oil in it for the phantom 85 because it was low . So really that's not a fair comparison. Fair to say??
Thanks for your subscription and I'm glad you're enjoying the videos. For the record, I used gas from the same can to refill the tank. So, that aspect was a fair comparison. I think my YD100 is just a lower spec than yours. It could also just be a dud.
I have same yd100 knock off rod had stamp but never seen it in video b4? Runs great. Im in break in 1/4 ,1\2 pulls me at 285 big back sprocket maybe 48 50? Way fast enuff did start with f2 pipe. Just breaking in then tune time or carb maybe. Also plan on diffrent wrist pin clips and shims between piston and rod to tighten up a little.
Waiting on an update for that bd-125 man
I got it back together and currently have a little over 300 miles on it so far. I got the rear wheel trued to within 0.020" and balanced it. It's still got some shake on the highway, but it's better. The gear change was a big improvement when I jumped up to the 17T front sprocket. 50MPH is now comfortable with barely noticeable engine vibrations and the shift points are a lot better for riding in town as well.
@@pulsar2121 very nice! Did you make any videos while doing the upgrades? I was hoping to see how you have done things so I can have a guide. I'm not mechanically inclined.
the85 is a game changer but they have so many issues going on with it I still got the version too I switched the Piston out it's been doing fine so far the original piston that was in it the bottom part of the Piston ended up blowing out all into the crank
Oh I also wanted to make a comment on the volume level of that exhaust....
Please use a chest mounted camera. It make it easier and better to enjoy and watch
Thanks for the feedback. I'll see if I do something about that in the future.
I'm getting the chainsaw headed yd100 off eBay. Dude builds them up, 139$
You have a link for that?
@@DesertSessions93 larger intake and Exhaust ports. Flow way more air then a stock yd-100. I think she kick some Phantom 85 ass
@@DesertSessions93 2 Stroke LD100 Motor-Upgraded YD100 Motor - 50MM 79C/80CC/100CC Engine Only , copy paste that to eBay
that yd100 has some balls you have a restrictive pipe on the yd100 and the phantom basically has a straight pipe on it with a Silencer on the end of it you should get some longevity out of her according to ERT they got there's up to 56 on a chain saw piston and it's still going strong when my chain saw piston comes in that's what I also am going to do ride safe
For the sake of this comparison, I wanted the YD100 to remain in stock form as a bought it. I'm sure upgrading the exhaust would greatly increase the performance as it is a very quiet muffler.
okay so.... did you try em, or just fooling around?
I'm under the impression that what you felt was the low end torque of an engine with a larger bore and cylinder and it spooked you. 😬 But honestly, your safety is the most important thing.
My pexmor 100cc had way more than this im so confused... i have the phantom v3 coming and hopefully it's all its hyped up to be
24:14 it's still idiling way too high after you adjusted it. You might run into overheating issues if you don't address that. If it overheats it will damage your piston rings
Your yd100 sounded like it was gonna sieze up on you ,you could definitely hear it on camera
49cc made for You!
Best suggestion...get a tach. Really does not sound like that yd100 is getting into it's power range.
Which tachometer would you recommend? I've always thought about adding one to my motorized bikes, but I haven't been able to find a tachometer for 2 stroke engines.
@@pulsar2121 almost all of them you will find have both a 2 a 4 stroke setting. Man I'm curious what happens to that p85 with the saw piston. Hope for the best 🤞
Amazon has several options
maybe the phantom has air leak that's why is idle crazy or maybe is like you said is only carburetor adjustment.
Cut groves into your clutch plate like the rotors on break pads.
Mine top out at 62 had it there like 3 times
The exhaust was quiet compared to mine LOL
My phantom rips up mountains so I think your lil hill climb was driver error. Cause these phantoms are monsters if you break them in right an take care them
What type of Sprocket are you using with the phantom 85 i live in a really hilly area i could go with a regular 88 cc but it needs to go faster than 25 or 30 miles per hour im going to start building one hear soon and riding out of town it needs to pull at least 35 40 mph
lol of course his experience didnt mimic yours so he must have done something wrong.... why do people take offense if something they like doesnt work as well for others? Even I am guilty at times of having those feelings. Maybe the way we are raised or media. Anyways I don't think that is a correct way to respond to things like that in life, we can all be wrong though. Some one elses experience is not wrong just because it does not match yours or your expectations.
That pinging is the engine getting a little warm. Not enough airflow at slow speeds
I weigh 105 kg and my Phantom 85 pulls me just fine. I wouldn't call it a race motor by any means.
Fair enough. Rider definitely has an impact on the power to weight ratio of motorized bikes.
It wasnt clutch slip, that motor has compression and it doesnt turn over easy like your little china dolls. That motor requires a solid frame, it is not like the bottom end it sits on.
Yes, I did notice after a couple of starts it seemed to be more of a compression thing. I needed more wheel speed to get enough torque to turn the engine over.
@@pulsar2121 ive had my phantom for about 4 months now, and it is a different motor. Reliable it is not, ive heard of a cylinder port catching rings, and ive had issues with mine. it isnt as practical as other china dolls, but i have mine on a huffy landlock, and it rides quite nicely at my weight of 240lbs Maybe one day ill post a vid here in the appalachians mountains.
@@christianhunt7382 Yes you have to order not assembeld and then use a rubber wheel and dremel to smooth the inner ports, then use a brillo pad for the final prep. this will insure no ring snags and better ring seal
@@pascalolesen5187 yeah bub, I was referring to startup and compression, I've got my phantom smoothed and mildly polished, assembled and running well. I need to seal my tank, I'm slow leaking by the petcock, and I believe it's getting too much fuel to the engine, not hitting powerband proper. Too much gas, not enough air.
Other than that, I'm thoroughly happy with my phantom. It will go up the biggest hill in my town, half a mile of 25% grade incline. Just gotta watch the temp, it's way too fun to ride, I dont wanna burn it up.
I got the yd and don't have near that many problems
I had the exact same yd 100 motor and it was way faster stock😒😒, maybe try pressing the throttle more than 1/4 of the way next time 😉
I attempted to make the comparison as fair as possible. I did indeed use all of the throttle at times for both engines. I have since swapped the exhaust pipe from the Phantom 85 over to the YD100 and it picked up a lot of torque down low, which suggests the stock exhaust was a restriction.
It's not going to go 45 or 60 miles an hour number one number two you have a version 2 most likely version 1 Phantom 85 the new version just came out version 3 and they worked all the bugs out of it it's got a balanced crank they also have solved this nagging issue of the piston rings on one of the ports inside the cylinder wall stainless steel needle bearings I just got mine in the mail about a week ago in a Thursday I'm waiting for the screaming demon from bicycle engines, which I hope is a good bike I hope they fix some of the problems on that bike but anyway you have old motor that has an unbalanced crank that's why it's vibrating like crazy also if your motor mounts aren't perfect
Man it seems like most of the phantom videos I have seen on versions 1 & 2 have detonated due to extremely poor designs. Sounds like you are having to use a YD head for a reason, curious if it's due to engine failure of a previous phantom top end. Your even being very gentle on it. Anyway, I don't know All the stories about them but they are $300 for the kit and that is a lot of money for me to spend on something that is probably going to be unreliable unless I baby it. I want to run the crap out of my bike!! Thanks for the video brother, I'm going to listen and STFU now. Laters
Your video didn't prove anything.If your yd 100 only does 30 its not right.Even with a 44 tooth gear should go faster.The phantom is junk unless you modify it alot.New piston and needle bearing.But thanks man.
Seems as though they used their customers as beta testers, I sure hope they are replacing some of the damaged engines probably not, IDK. But just seeing the failure points lets me know it was probably designed by an amateur that had done little to no testing. I know you sell engine kits, so you have to continue to test the new versions for homework sake, but I'm glad you have the guts to explain that you have had more failures than success and 80% failure rate after running for a very short time is straight up Bullspit. I will never get one of those until they have been defect Free for a few years, but probably not... I'd not like to put money in the pocket of those who obviously took advantage of the customers, that's wrong to hype them up and send them faulty equipment, in fact IMO it's unforgivable and unacceptable. It seems to me that even if they sent New parts they would still explode again due to severely faulty design. These things cost $300! Wow. Glad you were clear about the failure. Hopefully third is a charm, but All those guys who got versions 1&2 got screwed man. Not just one version but a second? Who built this thing, they need to be identified in case they try it with another name.
Your YD100 don't sound right. It almost sounds like it's 4 stroking. You may want to take the jug off and inspect it. Maybe needs porting.
Yd 100 is like a diesel truck 😂😂😂 you need to take the exhaust cap off for more power out the yd100
Wow 20mph had you scared. Wow too loud??? Mašne we should get you some training wheels.
Less talk more walk
ehh, I'm 10000x more interested in your 4 stroke build. Still gotta shake up the content.
Not to worry. There's still plenty of work to be done on the 4-stroke build that will inevitably become more videos. I'm glad you're enjoying the series.
4 stroke engines are bad ass

Yd slower than my 66cc I stg
Sorry buddy. I would keep watching but at the point where you talk about introducing air with exhaust leaks is where I stop watching. I don’t want to tear someone down so instead of cutting you off I’ll give a little advice. A 2 stroke with a expansion chamber will out perform a straight pipe 2 stroke engine. This is because of back flow pressure. Ideally you want back flow pressure but with the stock kits the exhaust systems don’t offer much as far as performance and back flow pressure leading to people straight (piping) there exhaust (pipe). This does have some negative long term affects. The engine will run hotter a little bit. If tuned correctly the straight pipe can be done but your cylinder won’t last longer than a cylinder with a expansion chamber. Bottom line exhaust leaks has nothing to do with introducing an air leak. Likely your yd100 runs better with the clip at the highest point of the needle. You did say it has 2 tanks worth of running so it’s brand new. More oil= more rich mixture of gas/air (not technically how that works) but if the needle is at stock setting more oil on a new engine would give the affects of running richer.
Thanks for the insight. Back in the day, I had run some china dolls with no exhaust pipe and they seemed to run lean. Basically a high idle and no throttle response. That was what I was basing that off-the-cuff remark on in the video. Your explanation makes more sense. I'm no expert by any means and stuff is bound to happen when putting yourself out there on the internet unscripted. Thanks for understanding.
@@pulsar2121 your welcome
ir probably didnt get damaged in shipping haha. he wrecked once that we know of. hes no stranger to speed or takin a spill here and there
Man u should rip it not baby it its 2 stroke throttle wide open bud
Bro barely gave the yd100 any gas
Maybe if you weren't idling! Give it some throttle dude!
I have 85 for food delivery work but this IS a crazy machine. Not comfortable at all. Noisy like hell.
Hey man, I hear ya. The vibrations and exhaust noise are wild.
@@pulsar2121 but fast and powerful
swap the carb
It didn’t sound like you got the rpms up high enough to prove anything on the yd100😂 & LA Hoover would’ve made it up the hill without dying out. He knows that the rpm’s need to be up a little more so it could make it with the Phantom or the YD100. Just sayin Bud…..
Neither this kid nor LA Hover id consider good riders. LA at least makes good content, but the best part i got from this was watching this kids reaction to not alot of speed. Get that phantom on a better bike before you hurt yourself kid!
Thought I was the only one. I can get my 66cc going more reliable than he did the yd100. I set my 66cc up for riding trails and would soar up anything he showed the yd struggle on.
It's a fixed gear bike. You can only do so much without riding the clutch and starting at a higher speed doesn't seem like a very realistic test to me. I was just trying to give some form of a real world comparison for the audience that made sense.
Sorry man but ur riding ability isn't really something I would film. It was making me cringe. Sorry mate
He definitely was pussy-footing on the throttle
That poor yd is choke-off
