@@pulsar2121 I think it deserves a rebuild. Though I gotta say, your local terrain isn't very suitable for these little two strokes. Without active cooling, and every stroke a power stroke you will eventually melt any piston you put in there.
Hey this is Jay I'm biking enthusiast have been for many years and I want to say big huge thank you and thanks to la hover I did not blow a bunch of money on the phantom 85 not the first one not the second not any thank you thank you thank you you guys saved me big cuz my old lady is already on me about spending this money for what she considers silly nothing that would have really been a big silly nothing so thanks a lot you saved me
I have had so many problems with 2 strokes that I migrated over to the 4 strokes. Once properly installed I’ve had almost no problems with them. Good gas good oil maintain the bike and have fun.
Bro,it was a bad move to put smaller wheel,sure more torque and lower speed,but then there would be less airflow,high rpm’s are a no go,and never go above 32/1.The phantoms are best when on a small sprocket and pulling on medium speeds.This was still a good test to see how much the phantom could put up,best luck to you,and hope to see another 80 cc video
I ran my Phantom 85 v2 today for the First time on a 30 minute there and 30 minutes Home. I was Very Impressed 😊 Love The Torque & the Smoothness of it 🎉... my ratio is 25to1First tank 32 to 1 for Life! Is recommended..44 sprocket Awesome 👍 phantom Fanatic!"❤😊
I know the phantoms have some design flaws but they are air cooled engines. Running that small rear wheel reduced the amount of cooling it would have had with a 26" wheel. I would like to know what fuel ratio you were running and how the carburetor was tuned.
The carburetor was left at the out of the box tune. The only adjustment I made was the idle air speed. Mix ratio was 40:1 with Polaris full-synthetic 2-cycle oil. As with any gear change that results in higher RPMs, undoubtedly, it accelerated the wear of the engine. The bike was just unsuitable for my use case with the 22MPH clutch engagement speed of the 44T sprocket on the 26" wheel.
@@pulsar2121 Um, ZTMoto recommends 20:1 for break-in then 25:1 thereafter. Running this engine at 40:1 certainly contributed to it's demise. Deciding to run WOT with a reduced size wheel and a large sprocket contributed... You killed that engine... it didn't die...
Oh... and I always recommend including an on-board temperature sensor on these builds. Knowing you were running 400 degrees would have saved the engine. They are pretty cheap too. I use a computer that senses temps as well as RPM... it cost about 35 bucks... much cheaper than an engine.
@@pulsar2121 I find this statement strange. I rock a 36T sprocket... and I can cruise at 17-18mph without issue. I can only imagine a 44T sprocket would result in a slow cruise around 14mph or so. This is also with a 26" rim. Was the idle THAT high?
Also, in all respects to what it is, you can kill any two stroke bicycle on land like you have. That bikes meant to do 25 mph comfortably. And im 230 lbs. Wide open land with wide open throttle is a two stroke death sentence.
Any idea why it overheated? Is it just a defective engine/head design? Running to lean? Maybe it sprung an air leak on the intake causing it to lean way out? I'm glad I never bought a Phantom.... I seen a Runleader digital temp./tach gauge with adjustable temp alarm setting for $25.......That $25 gauge could have saved this engine. After watching this video, a temp gauge would be the 1st thing I'd buy if I had a Phantom85. I'm tired of wearing out back bike tires so fast, so I'm gonna try something that'll either be stupid or brilliant. I found some discarded Micky Thomson dirt track car racing tires with no steel belts inside the tread. I'm gonna cut some narrow strips out of them & glue the rubber on a bald bike tire. Clean each with solvent real good & use rubber tire glue. If it doesn't work, I'll only be out some time & $3 in glue. If the glue holds, I'll have some bike tires that, #1 last way longer #2 more flat resistant #3 can handle the hot summer blacktop road temps without getting soft & melting.
Definitely ride safe, that thing is sketchy. It's really made for a bigger steel framed bike. I've had mine on a huffy lockland and it runs great. As to the people calling them junk, they're probably just repeating someone else's review. Mines been great. I've got hundreds of miles on mine.
what mix where you running it on i run stihl fully synthetic 25/1 mix i have 3 bikes and all of them are ported/tuned 2 x 100cc and a 110cc all where stripped and checked and cleaned!!
Port the YD100 please. 2,5 mm higher exhaust, 2 mm lower intake. You'll feel the difference. And replace that whiney clutch. That's subtracting horsepowers surely
LOL the vibrating seat was puting me in a bad mood which affected my commentary a bit. I have been stranded out of town on motorized bikes many times, but not every time. Usually it is because I was doing dumb shit like mudding or trying to go through slushy snow in the spring.
phantoms are junk right from the start . but i feel that most of the little bike motors are pretty junky . they last for years if you dont ride them lol . i guess its all in how you ride them some last alot longer then others . i think the key to even the ones that last is not to let them get to hot . there just not built to last . four stroke engines are really the way to go if you want something that will last and be dependable . but there are cons and pros for both .
Agreed. Two strokes are light and easy to just bolt-on and go and I love them for that, but at the same time having a dedicated lubrication system separate from the fueling is the dependable option.
I have a 80cc kit with a 100cc big bore on it no front forks or anything and it's perfect it overheats a lot like on my 5 mile commute I need to stop once and then take it easy the rest and when it does brake i.e chain or something I pedal it home like you should have done in this video
@@pascalolesen5187 I didn't have too much trouble with mine but then I brought one off my boss and used that every day and apart from it getting hot very quickly it wasn't bad until I killed it by overdoing it
@@pulsar2121 there's a few videos online and honestly there isn't a such thing as a perfectly balanced single cylinder. Just close enough and for specific rpm ranges usually
The FIRST thing I always buy for any bike is a comfortable seat! Why would you put a smaller tire so the rpms are always high? I have a temperature gauge on my phantom and it never comes close to over heating
damn bro sry bout thats, i got 70 mile on 50cc. just goin normal speed. i see that black oil came out your engine is probably too much oil mixing that why it over heat maybe.
That's why I wouldn't have a 2 stroke they heat up I have a 100 cc 4 stroke and run it wide open I also don't have to peddle it pulls it's self perfect.
Another one bites the dust!
lol RIP, thanks for taking the time to give it some good Brrraps.
No problem. Thanks for sending the engine my way. I appreciate the opportunity.
@@pulsar2121 I think it deserves a rebuild. Though I gotta say, your local terrain isn't very suitable for these little two strokes. Without active cooling, and every stroke a power stroke you will eventually melt any piston you put in there.
Definitely deserves an autopsy
They are pure junk and they build them in a dark room
Lol jus got 20mins out of my new v3 b4 it seized 🙁🐿

Do you run a 4 stroke kit engine or a custom fab setup?
Tell us more :> if you have those wide cranks, how do you find it to pedal?
Pedalling like waluigi
In the name of, science! Glad to see it’s outcome. Thank you for that.
How awesome is to have to push a heavy bike on the middle of nowhere?! Glad you safe and sound. Thanks for the ride.

Wrong mixture lmao my engine uses 40:1 cradle to grave idk who told u that

They recommend using 20:1 during break in and 25:1 after break in I would stick it 25:1
And thanks for the heads up before I went and spent $300 on garbage thanks merry Christmas
No problem 👍

My v3 did the same thing yesterday... 🙁🐿
You can see at 29:47 where the fins are bent down on the left side... possibly due to it being to hot 🔥
That's just from the mail man, but yes it did indeed get very got.
They will never get hot enough to melt

Its lacking fins to cool off the engine thats why its overheating

I'm glad to hear that yours is holding up for you.
Hi sir good morning could you please tell me if you swap the piston for an ms460 or did any mods?
what mix where you running it on i run stihl fully synthetic 25/1 mix i have 3 bikes and all of them are ported/tuned 2 x 100cc and a 110cc all where stripped and checked and cleaned!!
Good stuff. Wish they lived longer haha. Should I go wild cat pk 80 or zeda pk 80? Let me know what you all think?
For power zeda 80 for reliability pk80
Port the YD100 please. 2,5 mm higher exhaust, 2 mm lower intake. You'll feel the difference. And replace that whiney clutch. That's subtracting horsepowers surely
How do you only make it a couple miles out? I get around pretty far and fast but I do run a 36T and stick to pavement

What version phantom is it?
Have to be one of the most temperamental engines out there I’ve never had a problem as long as it was Super lubricated like 16:1 all the time
Damn, that's a lot of oil! How many hours of run time do you get out of your spark plugs with that mix ratio before you have starting problems?
Rarely
@@joebrown967 make a video bro 👍
@@JamesPiccone Make a video of what my engine running
@@JamesPiccone How do I get like subscribers and show off my bike and all that kind of stuff
What speeds were you riding at?
Hard to say without the GPS running. Felt like around 25-30MPH for the straight shot at the end.
Looks like the absolutely perfect riding spot
Hey why are the cooing fins all bent on the jug
That was damage from shipping.
Same thing happened to mine. I wonder if a two piece jug with a large finned head would help.
I think more cooling fin surface area is definitely the answer to longevity of an air-cooled engine.
hey when u st test the phntom from hover you ssid u hit 40 to 4 five is thst s guess ? cus mine with 44 toooyh only tops out 33 mph

To me it sounds like that idle is too high, or you had an air leak
If it vibrates that bad consider balancing the crank if you decide to rebuild it
How do you balance the crank on these engines?
@@pulsar2121 there's a few videos online and honestly there isn't a such thing as a perfectly balanced single cylinder. Just close enough and for specific rpm ranges usually

Yep ya screwed up! Either the carb was running too lean, or not enough synthetic 2-stroke oil in the gas!
Extra Excellent
That thang will go farther than 8miles
