I love how you can see the chaos in this machine. Horribly balanced (just the v twin in general not a dig at this machine it is quite nice) as it shakes around on the table. Very cool mini engine, one of the neatest I've seen on your channel.
A proper 90 degree V twin is reasonably well balanced (perfect primary balance). Narrow angle V twins (Harley and this model) with a shared crank pin are not great.
That's almost an exact replica of the old Harley Panhead engine. If you look at pictures, they even have the same lines cast into the lower crankcase cover.
Just like my old 57’ Panhead. Couple of things though🤨 1-It’s not leaking oil. 2-It’s rubber mounted 3-It’s not as loud🤣 Thanks for sharing the video post. Sorry the ignition fried on you. Best of luck 🍀
I HAVE A GREAT IDEA. Keep this on your workbench or desk.... Engine powered. pencil sharpener. Or an engine powered mixing bowl. Or just put a fan on it and have an engine powered fan but it’s on backwards so the air goes to you. Well. That last one would be pretty dangerous.
Is not the starter motor bracket, it is actually the alternator or in the case of the old "panhead" would be a 6 volts generator. The starter would go on top of the transmission on later models like the "shovelhead". This is amazing, i will order one for myself and will build a tiny frame around it
Johnny if you ever get a replacement hall sensor, it would be really wild to make a model RC Morgan 3-Wheeler. No idea how you would scale all of the unique drivetrain components but with you I'm sure it would be spectacular.
OMG! It's a miniature Panhead! How cool is that? I mean how could it be anything else with the shape of the sidecover, valve covers and distributor mounting?😁 👍 *EDIT:* Now why the hell didn't they put that Hall Effect Sensor *inside* the distributor?! Between the vibration and the oil contamination in the bottom end, they should have known it wouldn't last.🙄 Time to get busy with the lathe and your mini-mill and make some proper ignition parts! I know you've got the knowledge and the means to do it! It could probably stand some bigger diameter exhaust pipes while you're at it!😉 Crazy thing sounds like a top fuel Harley at idle though.. it would be fun to see what kind of mousepower it's making.🤣
The open mounting point is for the generator on the HD Panhead. Swap the exhausts to point the other way to get a more old style HD look. It is so cool!
Exactly what I thought! If he can machine some pieces to get that Hall Effect sensor *INSIDE* the distributor, it will be a big plus. From the looks of things inside that side cover though, he may have to use that generator mount and build a custom distributor, to avoid having to make hard-to-design helical gears for the existing one, since it seems that it's just a pass-thru for the sensor harness. At least with a custom distributor, he'd be able to control timing by rotating it for ease of starting and better performance once it's running.😎
Wow, it sounds really nice for such a small engine. We will get dyno video soon right? I wonder how it will sound under the load, oh and thanks for the video Johnny, top quality as always.
@@Dymitr_Nawrocki You can not get an accurate measure of an engine's output if you do not put a sustained load on it. Inertial dynos do not do this. They're great for making the engine under test sound nice but they will never give you meaningful numbers. Case in point, Johnny's 'dyno' claims the NR-200 makes 0.1-0.2hp but field testing by both Johnny himself and by others show that little thing to put out somewhere in the neighborhood of 1hp. Dennis Dempsey has one in a Trail Finder 2 and it bombs through tall grass better than any brushed electric TF2 I've ever seen, and those have more than 0.1hp on tap.
@@TestECull Inertial dynos are accurate but they measure engine power when it accelerates not when it is running at fixed rpm so they are not as good for tuning the engine but they are accurate, almost all of the dynos that are used to measure car or motorcycle power are inertia dynos, if they would not be accurate professional workshops wouldn't use them. The only reason load dynos are more commonly used as engine dynos is because you can tune engine while it is running at fixed rpm and you dont have to go to idle and accelerate every time you make a change in engine map.
@@Dymitr_Nawrocki Dynos used for automotive engines don't use inertia. The load they apply can be varied pretty much infinitely; this can not be done with an inertial design. These days most of them generate electricity and could easily be used to sustain a given load as long as you want for tuning purposes if so desired. Inertia dynos are not accurate measures of anything. You wanna know what an engine can do you need to put a constant heavy load on said engine. It's not just for tuning it, it's for measuring its output.
I had a friend who bought a 4 cyl. Honda motorcycle engine when they were first introduced and built a custom exhaust system for it. He mounted it on a stand in his garage where its only purpose was to make motor noises. He'd take visitors to see his toy and impress them with the shrill screams of 12,000 revs. I'm glad to see that that hobby is still alive!
Thank you for opening it up, I was thinking at the beginning I hope its like the toyan engines you build yourself and was quickly disappointed it was pre built. Really cool piece of engineering to have on the desk, even if it did destroy itself
@@metricstormtrooper Like David says - I ran a Moto Guzzi V-Twin for years, 1200 CC, over 100 horse - pretty smooth. Harley are unique in their ...... approach to engine design, which can generally be catagorized as "stupid" but it is open to interpretation, some people seem to love shaky, potato-sounding engines derived from 1950s technology.
because you don't produce your own pure 4 stroke gasoline engine and oil lubricated like a scale engine, I believe in your capacity and your intelligence I really like your videos keep posting ☺️☺️☺️☺️
I'm just picturing it on the front of a car, sticking out of the hood, set with the shaft longitudinally. That would make for a cool looking car, almost like a Morgan 3.
I dunno why, man, but I have the feeling *Stuart Little* is sponsoring you. Guess the black market cheese trade really did pay off after all, lolz. _Sweet mini-machine, as always!_
Oh my God!!! What an engine? Holy crap. No words to describe. Please make a bike like bobber or chopper for that engine once after the engine is fixed. Please..........
Aah, that's a shame (fried sensor) but I'm sure you will fix it and that it will run better than ever! Loved the idling too😎, can't wait for the vid 👍🏼
you should built a dirt bike design exhaust try to measure if it makes more power. I have heard Dirtbike manufacturers spend tons of time designen them for maximum power. you should be able to scale them^^
This would probably work if it was a 2 stroke engine because they benefit from the back pressure created by the exhaust (almost like a turbo charger). It doesn't work on 4 stroke though.
I hope the part is readily replaceable, quite liked the engines design though it does seem to need some tuning for it to run smoothly. Maybe that was caused by the malfunctioning hall sensor all along.
That's just how these V-twins idle. They have a very very rough idle and never run smoothly at low RPM. Doesn't matter if they're smol or big. And it's why they sound so damn nice.
It's amazing that it idled so rough at 1500 rpms. It is also amazing that it did idle down to 1500 rpms! Don't most small engines like this idle around 4500 rpms?
Ok quick note...On a Harley Pan head motor the Motor bracket in front you thought was for a starter motor is actually a generator mount and looking at the motor from that side the exhaust pipes go back away from it not in front like you have them now. In other words if you were sitting on the bike and looked down the fly wheel will be on your left and the carb will be on your right. So the pipes should sweep back the other way...! Very cool motor. I had a real 1953 Pan Head Harley..!!!

It pains me to hear and see this engine because it runs like it has a stopped up carb
Don't lump this piece of crap design in with all vee twins, Guzzi vee twins, especially the 850s are super reliable and smooth.
@@SkyPassYT it runs like a harley thats the issue
@@BIGSMOKE-bl2lqit sorta does but doesn’t at the same time like seriously it sounds and runs like it needs a carb clean bad
A proper 90 degree V twin is reasonably well balanced (perfect primary balance). Narrow angle V twins (Harley and this model) with a shared crank pin are not great.
Sounds amazing. Can't wait to get mine. I would love to make something like a Morgan three wheeler.
Hope they sort out the issue man.
I had same idea, RC Morgan 3 wheeler would be awesome!
Me too
What do you mean Morgan 3-wheeler? Like you would build the chassis and body from scratch?
@@Fluterra got it in one.have a cigar!
I thought exactly the same thing! I’d love a full scale 3-wheeler but for now would settle for building one with something like this
Yes an idling V twin I could watch and listen for hours.
My riding mower is a much bigger v-twin. 22hp Kohler engine actually. Even idled way down, it doesn't sound ANYTHING like this little beast.
That's almost an exact replica of the old Harley Panhead engine. If you look at pictures, they even have the same lines cast into the lower crankcase cover.
Looks and sounds just like an HD… vibration and self destruction true to form too! What are your plans with it?
@Qefna Ija you are not authorized here
Looks like an old pan head!
I hope he makes something for it
He just has to build a trike around it
Lol you’re spot on, similar to HD not any other Vtwin!
I'm surprised they would build that soldered hall sensor inside a hot engine. Looks like a fun project to make your own now.
Just like my old 57’ Panhead. Couple of things though🤨
1-It’s not leaking oil.
2-It’s rubber mounted
3-It’s not as loud🤣

Breaks down just like a real Harley, the ultimate in scale realism!
I am dying...🤣. Everyone always asks me if I like my Harley. I respond with "You know HD stands for hundreds of dollars right."
I absolutely love where technology is going. Did not have these when i was a kid....
Description:
"Get this engine here! 10% discount"

10% discount for your broken engine? Naaaah.... 😂
Johnny if you ever get a replacement hall sensor, it would be really wild to make a model RC Morgan 3-Wheeler. No idea how you would scale all of the unique drivetrain components but with you I'm sure it would be spectacular.
My initial thought exactly!
I don't know what it is about a Real working motor that has been miniaturized, brings out the kid in me.
You've featured some really cool little engines on this channel. But, this one is hands down the coolest.

There are two very diffferent groups of comments here: 1. Those who did not watch to the end and 2. Those who did watch to the end.
Hello,
This engine is perfect for you to make a motorcycle, or a Morgan 3 Wheeler ! 👌
God that sounds so good
I'd love to see this this one in a RC car!! All the shakes and noises will be amazing!
This has got to be my favourite sounding of all the engines you've tried.
One of the best sounding and most realistic model engines I think, I'd like to have this on the back of a beach buggy.

His dyno is basically worthless. It doesn't put a sustained heavy load on the engine and can't measure any meaningful amounts of output.

This is a good visual representation of how unbalanced a V-twin like that is.
42 degree Harley piece of shite vee twins.

90 degrees has perfect balance just a slight rocking couple if the rods are side by side

Am I the only one that gets hella hyped when Johnny uploads a miniature engine video?
No
Its a beautiful looking little engine....much like a Harley pan head.
You HAVE to build a motorcycle around that motor. A tiny Harley would be cool!
Then he could build a scale model cabin cruiser and use it for the boat anchor that a Harley really is.
this man knowledge about car machine really impressive, he know in and out how the machine works
I can just see a model Harley Trike with this engine... that would be something to watch
What a cool mini-Panhead!! You could do a "Captain America" chopper with that mill. If I had your shop, I'd jump at the chance. Too cool.
Sounds just like a twin too ! Awesome mini motor.

an RC dragster build with this engine would be super cool
I know that they don't mix,,, But I would love to see this motor in some kind of RC buggy. I just love the lumpy sound of it.
Great Build
As a mechanic , these videos are the cutest haha! I didn't even know about the mini twin engines! Awesome video !
You said everything about this Engine with these few simple words.
5:06 I CAN WATCH IT IDLING FOR HOURS.
That was a Pass, as far as I am concerned.
That thing sounds so good
Nice! Exhaust pipes need to face the other way though.
Make a mini Harley Davidson! You always have the coolest things.
that one tops them all you have shown .. I love it ! ENJOYED

You're back for another video! Yay!
.....and it even sounds like a Panhead! Very cool
Maybe use the flywheel as crank position sensor with a ABS sensor to provide signal.
man, it's so tiny and cute, it's really cool, congratulations on the great job
Very cool, I really like the sound of the machine. Thank you very much for a great video to watch and enjoy. FC from Thailand 🙏🏻🇹🇭🖤🤘🏿

One of these days I'm going to buy one of these engines you review and have it as the coolest damn desk ornament there is
Your title alone is teaching me stuff VV
You could plant it in the back yard and let it grow. In a few months, with regular watering, you'd have a killer engine for your scoot!

Please make a RC trike with this bad boy! Very cool!
the little baby spark plugs are my favorite
That looks cool just like and sounds like a Harley V twin motor. Can't wait to see what you do with it. 😀❤🇨🇦
Add a few feet of chain and a rope and use it for a miniature boat anchor.
It's 4-stroke engine, isn't it? But runs on 2-stroke fuel? Interesting design
Instead of a tiny super complex oiling system you can run oil in your gas on a small engine like this.
"And that's the last time it ran"
Typical Harley Davidson shenanigans.
That's a baby Harley Davidson Panhead!!! OMG!!! Take my money!
Loved the engine! Like a real motorcycle!
Ooohhhh that idle ❤
That would look cool in an open wheeled tether car!
Incredible little machine
very excited to see what you do with this one next
Balancing, porting, maybe a hotter cam... and some basics like engine mounting, dampening, carb return spring.
Cool little 'pan' head!
That sound! it sounds beautiful
This is just the coolest
COOL!!!! minor issue, I am sure they will rectify the issue for you... Thanks for showing this..
amazing to think this thing is more powerful than some of the first motorcycle engines
Dang that sucks! I hope you can replace the Hall sensor. The sound of that engine is amazing.
