at the beginning it looked like an Allen Millyard project but this more like a Dick Strawbridge & Allen Millyard Scrapheap Challenge Robin-Honda special. quite incredible repurposing, adaptation, recycling and good raw engineering skills.
I've been following his channel for a long time, before this brand new channel, he build more than on this channel, unfortunately, his old channel were hacked 😢 He is truly my inspiration, never give up on everything 😊🎉👏🏻
My man must have some kind of engineering degree, he takes that already made and makes it much better. Nice job Mr Dan, can't wait to see what you build next. 🎉
So cool! Afaik so far, there was only one production motorcycle ever built with a 2-stroke boxer, the IFA BK 350 from GDR. There was also a 4-cylinder double boxer by König (Germany) for racing, based on a boat engine.
Thank you Le Dan for your perfect work,making a little boxer from used Honda's parts like you do astound me 😮 as an engeneer you made this happening so easely...Your knowledges on material résistance are good and all on this pretty little bike have its place 😊❤ love it !
The porting on the piston is set for max power at low RPM . Cause it’s a lawnmower engine not a high RPM engine. You might have to do work on the port timing. I see it smokes back through the carb which indicates it can’t blow out the exhaust gases to match the intake of air and fuel. Nonetheless still a very cool build bro!! Great skills you have!!👍
Wonder if facing the intake side of the carb into the wind would help push all that fuel mixture in, a reed valve system wouldn't be a bad idea either way and could probably make a reed cage that just mounts to the intake before the carb so he wouldn't have completely redesign the entire system.
@@kcraig51 It is now a boxer with a common intake, so one piston is at TDC and one at BDC. As soon as the piston port opens to induct, the other piston crankcase is opened up to it. What ever pressure difference there is has to go somewhere and the only escape route is the carburettor inlet. It needs reed valves on each crankcase or two carbs.
Wow there are some clever people in this world. It sometimes over whelms me watching what others are able to achieve by thinking outside of the square, sometimes it's due sheer raw intelligence or necessity. Oh whatever it is I love it
I once fixed a zipper on my backpack that had lost its pull tab by putting a zip-tie where the pull tab had been. So I can totally relate to this video. Unconventional engineering is just easy for some people. What you did was pretty awesome for sure. Not exactly sure if its as good as my zip-tie zipper but its definitely up there. 🤔
Very Impressive 🤔, Nice Work, Many Hour's Of Machining And Planning, And It All Paid Off Very Nicely 👍, This Video Reminded Me Of The Many Different Prototypes Of Early Motorcycle Designs, That Both Succeeded And Failed Throughout Time, Very Nicely Done 😲🫡😁👍 !
Two cylinders running off a common crankcase often has this exact problem: because of slight differences in rod length, ring height, etc while the intake, transfer and power strokes are synchronized and one cylinder robs power from the other. The most common way of preventing this is boosting the pressure in the crankcase which brings its own issues with blowing out crank seals.
Put four cylinders around one crank pin and you’ll get four bang per revolution and almost zero vibration. There is no crankcase compression so you will need a blower to feed air. But it should be very efficient and powerful.
I don't understand how you managed to get a 2 cylinder 2stroke that has both pistons sharing a crankcase, with both strokes moving alternately, meaning as I can see, no crankcase pressure?? as the vacuum inside the crankcase from each pistons upwards stroke, would be canceled out from the other pistons downward stroke right 😐? I can imagine it working great with external pressure from a super charger heh heh.
The piston doesn't shares same big end. the big end installed 180 degrees from each other. So the pistons always move opposite direction from eachother, so its creates vacuum between when pistons move to TDC. And push away the air when pistons move to BDC
might be able to make it a little more efficient if you put a reedvalve in the inlet , this prevents blowback through the carb
Yeah, in the center of the cranckshaft would be aweasome
Yes reed valves on each barrel and separate carburetors to stop the pulses from interfering
@@BrianjSiehr naah, 1 carb is good since this engine does not produce much power
It is a piston operated intake. Instead of reed valves the piston is controlling opening and closing the intake

Beautiful job! A work of art! John in Texas
Those expansion chambers are adorable! 😀 And made BY HAND!! 😜🖐👍

I must say this is definitely one of the coolest custom engine builds I ever saw maby ever!!!! Gosh Dang really Fine Work. What a beauty!¡!!!

I get the feeling it would truly benefit from some thorough fettling.
As others have said, reed valves will fix that issue. Port timing/overlap that makes upper rev range power creates this issue at low rpm
Needs reed blocks in the intake. fantastic build.
Piston port engines don't use reed valves. Notice no reeds in the disassembly of the original engine.
Might be worth remembering they started out as lawnmower motors,
they're unlikely to use or need reed valves.
Wonder if facing the intake side of the carb into the wind would help push all that fuel mixture in, a reed valve system wouldn't be a bad idea either way and could probably make a reed cage that just mounts to the intake before the carb so he wouldn't have completely redesign the entire system.
I agree. If you see fuel blowing back through the carb, that pressure is coming from somewhere. All it would need is really light reeds.

May God bless your hands and your mind. Brilliant Dan.😊
Somebody stop this madman, there is no end to new engines!
You build some amazing engines.
A true knockout !
Well done all around
You should add the alternator stator to recharge the battery 🙂
Very nice creation ❤
Great work as always! 🏍💨👍
Another fanatastic build. Great.
he was a real mechanical engineer
There is nothing like the sound of a 2-smoke! Reminds we of my youth when most street bikes were such except Honda. Great machine!
You , Sir, are brilliant in so many ways.
Fine craftsmanship indeed.
Wow there are some clever people in this world. It sometimes over whelms me watching what others are able to achieve by thinking outside of the square, sometimes it's due sheer raw intelligence or necessity. Oh whatever it is I love it
Awesome little engine. Looks like a 2 stroke version of a BMW.

i don't have words to describe how good this is ....great skill ...great work
we want V10 two stroke turbo !
He needs donation for develop that thing
Nice work as always!

Great skills....You are a genius💯👍👍
Amazing job, well done 😊
Man, you are a genious!!!
Genius Mechanic😄👍👌
Wow. awesome work! That's a very nice bike you made!
All hand made .he a genius . All hands up amazing. Love he's work 💪
Excellent workmanship Sir. What a great idea.
Awesome work .yes a read valve or twin carbs/filters be a good addition
Awesome skills!!
You are AMAZING Le Dan truly......Thanks very much....

Better than a BMW and looks real cool too.

Nice idea, good engineering, respect
Incredible work. You turn scrap into gold.
I'd like to see a twin cylinder made from two Honda Gx200 engines. Any type, inline, vee, or flat twin.
Genius! GJ
Amazing work and ideas keep up the good work
This guy is awesome

I know you've heard it a thousand times, but I have to say it - 🤯🤯🤯🤯 My hat is off to you sir!
My favorite is when you fly cut the big gasket surfaces! SO Satisfying! 😋🥰Well, that and when you ride the bike down the road!! 🤣😂
