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.
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!!👍
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. 🎉
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 !
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
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.
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
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!
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.
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.
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 😲🫡😁👍 !
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. 🤔
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.
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.
👏👏👏👏👏👏 more than 30 min of my full attention! Again!!! As a simple technical comment, I really don´t like how it sounds well when idling (damaged connecting rod or crankshaft bearings?) but , wow, when you open the throttle, it sounds just like olders BMW R Series!!! Man, you're worth a lot...keep on!!! 👏👏👏👏👏👏
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
That is some remarkable work! I'm amazed at what a human mind can come up with, and then to have the machining skills, welding skills, and other technical knowledge to make this work out. And it looks super cool to boot! Good on you. The idea of splitting the ignition spark between two spark plugs is something I'd of never thought of. I was wondering what you going to do about that through the entire build, especially since I saw that you resolved the balancing issue by remaking the crankshaft and adding a second rod journal. I guess with a two stroke you needed to do it that way. This was a very interesting and super cool project.
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.
It obviously isn't going to be a performance machine made from a couple of old stationary engines, however to make something like this with basic tools in that environment I give him ten out of ten. Well done !! I do wonder why he didn't fit separate carburetors to stop the pulse problem and a central crankshaft bearing with oil seals or possibly reed valves like I had in my motocross bike ? maybe the Mk 2 will be an improvement ? Saying that, it's all very well sitting at home nit picking when I couldn't make it !! I do like his safety footwear though🙂
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

Yup and it sounds like a cylinder is down just like most STI's that go by. Nailed it!!!
You would be someone a person could learn from, "Amazing talent" ....
Awesome little engine. Looks like a 2 stroke version of a BMW.
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.
