Back in their day the West Bend go-kart engines had their carburetors bolted directly to the crankcase using a reed valve. As a matter of fact they were set up to where you could bolt carburetors on three different sides of the crankcase as it was possible to have six carburetors two on each side. But most guys ran two carburetors for a maximum images.app.goo.gl/KsATgYrCc8st84j7A

This guy gives me so much motivation to keep going for the result you've always wanted 😌 In my spare time I love to do what you are doing, im more of a 4-stroke guy but still its wrenching, designing, engineering,... you know. Been watching your videos since you weren't even designing your own engines 😅 Just graduated BSc Automotive Engineering but you got me convinced to study MSc Motorsport Engineering. Still can't imagine knowing so much about engines than you do, who knows we might race eachother one day 😉 keep it up 💪👌
Considering that is running way down on it potential it sounds like its still hitting some revs even now get that nitro methane working and its going to scream like a demented banshee
This made me remember something i did 45 years ago. I welded a piece of tubing to the rear transfer port of a G5 Kawasaki cylinder. It was maybe 12inches long and i bolted a 22mm carb to it. It actually ran pretty good, i think i got away with it because the intake was long and the carb was small. I had heard that the factory racers were doing this to their 125mx bikes(pre KX)
The one thing I love the most is your duality. On the one site CAD, CNC Milling, 3D Printing and searching for the last bit of power. On the other Site ducktaping a lawnmower tank onto a selfmade dyno . A proud German fan👌🏼
As a casual watcher I love you application and honesty to the process. I would find it interesting if you had a rev counter on display as it sounds like the engine is already spinning at massive speeds. It's great to see someone committed to pushing the boundary keep it up.
This has been so educational for me.. I really didn't know a lot about 2 strokes before.. But to watch this thing grow (and take on a life of it's own) has taught me a great deal.. though at 70 there is not a lot I can do with the new found knowledge.. But learning for it's own sake is still fun! Carry on!
Intake and pipe is good to be adjustable. Final adjusting in same temp what salt lake is when attempting. In fixed rev, is able use automatic tuning by dyno. It make adjust to get max torque.
The Prince of persistence 😊👌🙏👏 The Wolbro carb brings back old memories of racing karts. We used to drill out the passages and install bigger jets and run the engines on methanol. I'll never forget the smell of Castrol R oil
Very cool👍 We need a rpm display or something to compare different settings. Great work. Also a list with all the donors for that project would be cool to see that a lot of fans helped u to succed with that project. Keep it up, resonance!
When cutting smaller sections of silicone hose squarely l always push it on to a mandrel held in the lathe chuck and part it off with a very sharp HSS parting tool. Works a treat
Don't know if it's not important, or because of the prototype/experimental nature of the system you are building, but it looked like exhaust gas was venting out of the secondary carb (sometimes), one thing I all ways stick with is the knowledge that a force will always travel the path of least resistance. You are doing great work👍🏻
Oh, i think i will capture audio from these videos and use screaming 2-stroke as alarm on my phone. Sounds good! Nice that this concept is working and advancing.
This has me excited to plunk go-fast parts on my 2-stroke bicycle at home, alas, I'm a couple thousand miles away... let's see that dyno load up an engine Alex!!
The pulsing in the secondary intake is visible, it throws out as much fuel as it sucks into the engine, but with the long trumpet on the sliding valve this will be no issue as the pulse reverses before reaching its end.
Looks like the resonance from the pipe is forcing the air/fuel from the crank case out of the secondary intake. You can see it happen later in the video
Love again from Romania,Arad...I told you since an year that the exhaust is too large,will broke the rings,the piston...Done!Broken!Now,you need a few holes,0,3-04 mm,for cooling and oiling the bridge... Your electronic ignition is too heavy,the rotor,too much inertion...Try something with Foto-cell,type Krober from Kreidler Van-Veen..Your RPM is braked...Succes...!
I've been following your videos quite some time now. I envy you for your insights, dedication and tools🤣 Mist be a challenge with a family "on the side".. Cant wait 2 see the end results! Not long anymore with this momentum you've build up i guess
Great video again. Could you just reverse by 180° 3d print secondary intake manifold, and the fuel from secondary carb could better fly in, maybe it helped... :)
2:55 smart way to cleanly cut tubbing!! Also love the fact you build everything from or almost from scratch but i think you will start to get comments after you finish the build "fastest 2-stroke ever" about your i am dyno sure its fine but that 1% of haters with doubt the charts take it to a dyno shop get real certified numbers to show everyone!
i genuinely think big motor names will be interested in you , your ideas , and lack of fear when it comes to creating new boundaries. unless you become a huge name yourself eh :) i love your videos man. always watching 👌🏻
twin carb single cylinder Honda used a small diameter primary carb for low rpm higher torque off road rough trail and the secondary much larger bore carb came in after half throttle to WFO
In the mean time, as a way to load the the motor, why don’t you use the system that older stationary bicycles used? A large flywheel with a friction material wrapped around it. Then take a heavy nylon strap, wrap it around the flywheel, and tension it it to get a load on the flywheel. You can adjust the tension to adjust the load. Then the motor isn’t allowed to run away from itself, and makes tuning easier.
You could rig up pulley to a fan in order to put some load on it when testing. I would think that the load would scale very linear with rpm and could blow some of the exhaust out of your shop as a bonus. As long as you be either on , or off the throttle (accelerating or decelerating) you should be ok at high rpm. It's when the engine is at high rpm and reaches that point where it's doing neither that things go Kaboom!
Awesome work Alex , main jet to small if dieing after half throttle, But could also be spot on with adding extra fuel with secondary intake. If me I would tune carb dyno run then add secondary intake/fuel see where the gains are great work.
It’s been really cool to watch your progress. Do you have a video about intake/carb size and tuning? In your videos it looks like you know exactly what you’re doing every time and I’d love to know how you figured out what the air flow and fuel demands would be.
so slap a reed valve on the old test carb just to stop positive pressure pulses screwing with it... and maybe a YEIS bottle to smooth it out. You can see the positive fuel mix exiting the carb 8:24, luckily it didn't backfire or hilarity may have ensued...
A carb at the end of a resonant inlet pipe is likely to suffer horrible stand off as the pressure wave will pull fuel out of the jets going in and going out. With the injected setup is the fuel going to be injected at the crankcase end of the tuned pipe?
Have you thought of hooking it up to an airbox for testing? I know its only temporary but I think something before the valveless carb with all the spray would help rather than pulling in fresh air.
wouldnt it make more sense to make a cylinder with two intake ports and one exhaust port? then you can jet one for the lower revs and the other for higher revs?
Thanks for watching! I've ordered pulleys & belts for the dyno, time to get this show on the road!

When the Dyno is completed we have a horsepower display, a lot more useful than just rpm.
Fantastic proof of concept. Fine tuning this setup will be difficult but I think you have started in a positive direction.
When cutting smaller sections of silicone hose squarely l always push it on to a mandrel held in the lathe chuck and part it off with a very sharp HSS parting tool. Works a treat
You are a genius,I love watching your video’s and how passionate you are about 2stroke
if youre using an electro motor as the load you could start the engine with that electromotor
Racebikes dont have a starter , uneeded weight
Congratulations on the proof of concept for PiP with resonance charge/scavenge. Very very exciting.
This is just amazing
In 10 years all 2 stroke dirtbikes vill use ur patents n inventions❤️❤️❤️

It's just fresh mix being pushed out, will go away when in resonance.
@@2STROKESTUFFING Then it's all good, for now, also, then, no smoking on that side of the engine!
This is so cool. Can't wait to hear that thing rip on the pipe with the secondary carb wide open. I love it.
Yes man loving these vids man from Australia ❤️
"Just to see what would happen"
A phrase to live by!!!!
Fantastic to see it running, I know there is a lot to do but it’s going to be amazing,

Nice that this concept is working and advancing.
That's impressive!!! Lots of fuel standoff but that's hardly surprising with the"suck it and see" setup.
Sounds very crisp and responsive. You could clearly see the blowback through the secondary carb though.
Congrats on another successful run. One more step closer to your goal.
Again a lovely video!

You could run it diesel like, using fuel to partialize throttle
Running it lean will seize a 2 stroke
@@ametti000 he's got injection, he can keep lubrication up with no gas
Maybe its pulling extra fuel from the pilot jet on the PWK, and thats why it cuts out on full throttle?

I like the sound of it.
