I don't think that bike will be breaking any world land speed records. I doubt very much if that engine would last more than a hundred miles. But great fun, and the bike looks good too.
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. 🎉
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 !
If this guy had real legit tooling and a modern machine shop and CNC like I have here, he'd just be incredible. I cringe at the design and strength of that crankshaft, as that will be the failure.. but for the tools he had, I'm just in awe at how well he designed and hand-crafted this. I could not do it because of time, and lack of sheer knowledge of 2-stroke engine design.. but WOW! Amazing job!
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.
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.
You are so much more clever, industrious and talented than I will ever be. This was amazing to watch. You just fabricated a completely different motor from bits of a couple of motors. It looks like you've done this a time or two before.
Velocette designed and built just such an engine but with a reed valve. Your achievement is remarkable. With reed valves you can cut back the piston skirt as it does not need to block the crankcase port, reducing friction, but you would probably need to enlarge the exhaust ports.
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
Haven't watched the video yet, but the title said "boxer" meaning both pistons move opposite eachother. This is different from a 2 cylinder "flat" since the flat has both pistons moving in the same direction as you described.
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 😊🎉👏🏻
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
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.
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.
Everybody seems to have some sort of negative thing to say about whatever people make, but they'd never show us themselves making something out of nothing.I think the guy did a pretty darn.Good job and it's stuff like this but that I like to watch instead of some so called influencer going out doing stupid pranks on the public
I see he has a safety glove for his left hand [work vice] and safety soles.. what more could there be what! glasses u want glasses? I saw some glass fall from his facial altitude so clearly from falling safety glass at 6:01.
@@discoverneweyes I'm also convinced that the carb is not supposed to spit raw petrol out the back... he's got a potential flame thrower there as well. So if you take into consideration his attention to PPE, and his safeguards NOT in place. I can see he will get his leg hairs all burnt off and the soles of his feet ripped off when he stops! But at least he can tell his friends he built a 100cc motorbike out of two inexpensive lawnmowers and a 1970's bike frame! LOL
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 😲🫡😁👍 !
The carb is angled in such a way that one cylinder gets more fuel than the other, that's why the one on the left is kicking out a bigger cloud from the back.
. Its a horizontally opposed twin cylinder engine. I'm afraid you've been suckered by Porsche porkies. Boxer engine have 2 pistons per cylinder. The pistons move in opposite directions like boxers fists. .
You sir are the incarnation of Burt Munro and this the best compliment any person can give you. Amazing workmanship and know-how.

Красавцы, слов нет! Смотрел завороженно, с раскрытыми глазами весь ролик. Мое почтение. Работа великолепная
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

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.

ワンオフでここまで作りこむとは 素晴らしいです あとはキャブセッティングすればいいエンジンになるね！
Victa Lawnmowers in Australia produced exactly the same flat twin at 175 cc , it was in their mowers in the 1970s
Those expansion chambers are adorable! 😀 And made BY HAND!! 😜🖐👍

I like that, it’s really different and unique. This guy’s really creative. His innovation is fantastic.
Great ability and inventiveness shown here! Add another 4 cylinders and its a flat 6!

awesome job, 1 watch a lot of "I use this to build that" videos. Even though I am not talented enough to build an engine from a kit. lol
Thank you for the content you produce in your videos. I enjoy watching you rebuild these engines in new and imaginative ways.

The carb is angled in such a way that one cylinder gets more fuel than the other, that's why the one on the left is kicking out a bigger cloud from the back.
You sir, are awesome 👍
you might wanna straighten out that carb, its putting more fuel in the left cylinder causing imbalance on power
Wow. awesome work! That's a very nice bike you made!
Amazing job, well done 😊
Another fanatastic build. Great.
