Updated motor with improved bushing is on the way. Update soon!

[@Intersauto]

👍

[@thomasgoodwin1639]

Ya I got one it's not blown up yet so I am going to try getting in touch with them and see what that say

[@joneserupinsmoke9161]

Hey do u think it might have been the jb weld u filled the transfers with seeing how it's gooey?? Or is that how they come? I really didn't notice when I put my cylinder on

[@aaronalbers6871]

Is the newest version fixed

[@MJTechChannel]

I saved my motor on time. I could hear the rattle from a first start. The failure is due to that filling wearing off.

[@LAHover]

I saw your video about it just before mine fried.

[@MJTechChannel]

@@LAHover Darn it! I even have an extra bushing

[@jaayse]

When you take it out of the rod you can feel how weak it is. I haven't even ran mine yet because im waiting for bushings that I just got in the mail. Hope to finally fit it on💪💪

[@gta5grindzxb145]

I got my phantom 85 kit last month, do any of you know if it falls in the same type setup as the failing engines? 🤔

[@MJTechChannel]

@@gta5grindzxb145 It does, all of them do up to now.

[@dacianazerinity2052]

So watching this I decided I should probably check my engine just on the off chance that something was amiss as I was beginning to hear some chittering coming from my engine. Well, good thing I did. The cylinder is scarred, the piston is scarred, apparently my wrist pin retaining clips are shot and I caught everything one step away from total engine failure. Thank you for this video! You just saved my engine and my wallet. New cylinder has arrived. New piston will be in soon, and hopefully I will be back on the road again singing along within the next week. I can't thank you enough for your videos and everything that you do. Please keep making them, you're likely saving more people than just me!

[@fullmetaljacket7]

Man, that sucks. I think it's just too much power for a bushing to handle. They should use a needle bearing in there instead.

[@jeremiahdssdentmorgan3341]

[@AllConsumingJAWS]

Dang... We will never know. Sorry the motor let you down. We all were waiting for that top speed run.🏁 Hopefully the Phantom 2.0 brings you better luck. I was thinking 42 mph + with that setup.

[@LAHover]

Sorry :( she blew right around 38mph... Will test the gen 2 when it drops.

[@AllConsumingJAWS]

Looking forward to round 2. I had a nice little ride today myself thanks for the inspiration.

[@jaredbourgeois4722]

I've just bought the phantom 85 gen 3. I installed it today. When I assembled it I used STP oil treatment on all of the moving parts including the rings wrist pin bearing and lower rod and main bearings. I love STP oil treatment, I use it on my chain as well. It is thick like honey. When I received my phantom 85 it had the sticker on the clutch cover that indicated it was a V2. My engine came with a needle bearing for the wrist pin, which indicates that it is a V3. I guess they realize that the version one and version 2 were failing with the parts that were provided so they went into all of their boxes that were ready to ship and included the needle bearing. I also noticed that the cooling fins on the engine are very small and insignificant compared to my ld100. I had an old plastic fender that I cut in half and made pretty good looking fairings out of them that direct air onto the motor. I know that the top end is modeled after the ms460. It looks like an exact replica which means that it would require a housing around it and a cooling fan to supply continuous air. Well I just put it together today and put about an hour of run time on it with a 16 to 1 ratio, with a little smidgen extra oil too. Extra oil cannot hurt. I have experimented with a two-stroke weed eater. It can almost run on pure oil with no fuel. Extra oil can never hurt. I have a spark plug that is completely filled with carbon on the inside where the electrode is. It hasn't found out yet and it's still running. When I swapped it for a new one I noticed a decrease in power. I think that little bit of space that that carbon filled in the spark plug increased compression. I'll be riding it to work in the morning. It seems like a very strong and smooth motor compared to the ld100. Oh well good night smooth sailing..

[@jeremiherring3852]

I received my gen 2 replacement yesterday to. I hope we all have better luck with this one. Keep up the good wrk thanks 👍

[@LAHover]

Fingers crossed!

[@Chishado]

I'll probably check this engine out next year

[@MOTOX45]

I used my engine for about 5 hours then the bottom end locked up. Once I took the engine apart, I believe it was pieces of the bushing got into my crank bearings causing my failure. The wrist pin was in but because the bushing shelled, my piston was rocking side by side instead of just front and back like it should rock back and forth. Bicycle Engines is sending out a new motor to me once the new parts show up to get upgraded

[@artofdisguy3401]

No point putting the same stuff back in, hopefully they do the ms440 piston and bearing swap

[@davidrussell8918]

I thought useing bushing rist pins went out of style in the 60s.and everyone went to needle bearings because the problem you had. Running 20 and 32 to 1 oil mix is not enought oil for a bushing. Some companys used to have a small hole drilled through the rod from the rist pin to the rod bearing to bring more oil to the bushing. Most of the motors that used bushings in their motors for ristpin or any other bearing used a 16to 1 oil mix. Mabe its just me, but useing that chainsaw head/cylinder with the head fins faceing the wrong way doesnt help anything.that was designed to have a fan cooling it. I would think that motor is running to hot. Its to bad your having a problem. Sounds like its a nice running bike. Hope you get your problem resolved.

[@derekpirie9188]

I agree that the small end could do with a needle roller bearing. As for the head fin direction. This was designed for ducted forced air cooling. Changing the direction to inline, front to back, will help with the cooling.

[@Hunter1st]

Exactly what happened to mine. :( Luckily they seem to be a great comp[any are taking responsibility for it and sending out replacements at no cost.

[@LAHover]

Yup, got my gen two a few days ago, and so have a handful of other builders. :)

[@gelid1578]

LA Hover would you ever be willing to review a motorized bike from Sportsman Flyers. They build board track style bikes and I barely see any reviews on them. I’d love to see you buy one and turn it into some speed demon. My dream is to one day become a board track racer but I can’t get my hands on anything.

[@LAHover]

Maybe some day, but way out of my budget for now.

[@SamZStuff]

My very first engine kit I bought many years ago came with a bushing instead of a bearing. It also failed after minimal use.

Thanks bro...

[@willardbuchanan9122]

A lot of them are wash the casing out with gas first before firing them over for the first time and he usually flushes all the trash out of the casing

[@gabrielcarvalhogcr]

8:11 i think it whould be a good thing to test taking of the material that goes from the transfers to que crank case to increase flow to get much more performance because flow is one of the things that maters the most, or at least round it all so you dont take out too much primary compression

[@NicksBikes]

I was half expecting you to split the case lol

Wow so disapointing . Ive shyed away from these engine because i could tell the manufacterers didnt take us serious and sad to hear it carries over to the moto85 . If they can be reliable and consistantly manufactured consistantly i will buy 1 . I wish Japan would notice us and make them . My Zanoah G430 has 2.2k miles and runs better than when new . Only had to change fuel lines in the 2 1/2 yrs ive ran it .

[@Mishakol1290]

So taking the top end apart and the piston off is relatively easy? You don't need a ring compressor or anything? Never messed with a 2 stroke engine but I have torn apart and re-assembled a 2.0 and a 2.2 liter fuel injected car motor. These motors seem very simple. I am not trying to risk it though. Thanks you have a interesting channel.

[@sandmanbub]

@Whoop!!

[@trevormurphy7041]

I think they already knew about it that’s why they pulled them so fast I think they were just using people for a test subjects but like you I really want one of these motors

[@derekpirie9188]

Now, that is what you call ''Breaking it In''. Can you not fit the needle roller bearing instead of the bush. Waiting for the follow up on how they are going to address the issue.

[@ChuckHaney]

Those handle bars remind me of insect antenna or rabbit ears. Maybe paint some yellow stripes on that black frame and go for a hornet look.

[@patrickgreiner4288]

Honestly a larger opening in the upper knuckle and a roller bearing

Hey. I got a question. Do you think an expansion chamber would improve the Zeda 100’s power band as I’m looking for an exhaust or would another exhaust better improve the power and top end. Thanks in advance.

[@nipper4369]

sadly I was one of the first but I barley got 20miles on mine before it locked up my piston rings. They sent me a replacement but waiting on bushings still.

[@kjohns1413]

That motor is about as reliable as a Kia. Hopefully they can do something and you can make it a reliable ride.

[@codelicious6590]

Wow, I dont even understand how that bushing could have worn so drastically so fast! Inferior materials maybe? I mean, it was tight when it went in right? I think we all saw it. Yikes. I think it needs to be made from bronze but bronze isnt expensive, Hmm, I wonder what it is actually made out of to wear like that?

[@LAHover]

I've heard bushing can be effectively used in high power motors. So I'm guessing it was just a matter them choosing the wrong kind of metal... Updated version is on the way.

[@nutbuger1201]

What are you doing to revenge vibrations at high speeds these things rub on my brain going 30

[@LAHover]

On most motor I have found that they will normally do 30-35mph without vibration being a big issue. Some will even do 40mph relatively smooth. Past 40mph most will need a balanced crank. If you are having vibration issues under 30mph it is likely caused by one or both of the following. Carburetor needle is set to rich, and/or at poorly mounted motor. Those are only the most common issues, but there are more.

I would think out of all the small engines out there, there'd be a roller bearing & wrist pin the correct size. I guess not, which is why the Phantom uses a bushing instead of a bearing?

Is there anybody reputable out there? Doesn't seem that there's any other ready-made product I can think of on the market that seems to have so many issues and pre-installation rebuilding.
