Seriously, it's so obvious now, wohoo!(imagine the down if my fix makes no difference...)
Anyways, thanks for watching! Btw, this was filmed with anamorphic lenses in 12bit raw, transcoded to and edited in prores 444, rendered to prores 422, and then completely destroyed by youtube's compression. Just had to get that off my chest😁
Looks great resolution and focusing wise(quality)... but the color accuracy to me looks off, there's a ryobi green looking fan in the dyno shot and the red bottles in the background don't look as vibrant red as I think they do in person. But then again your video style for colors being warm is pretty unique compared to other youtubers. Gives your videos a Homey feeling.
@@Pro5.0 😁 I'm slowly moving towards more color accuracy.
TH-cam loves to wreck the best of efforts. Still, at least with great starting content you still get good results. Many thanks for the hard work in all the aspects ( videography and of course the maddening journey itself ).
If you aren’t trying to show us something small, it probably won’t matter. You get an experience lesson in video making.
One trick I have been using to got around that when watching videos is to play them in 4k even if you do not have a 4k tv or monitor, it does wonders with getting around the youtube compressing everything to death problem.
Oh man, I've almost gotten used to these videos leaving us on a clliffhanger but this one really makes me hungry for more.
😁 It's just as much a cliffhanger for me, I'm confident I've found what has been the main problem all along, won't know for sure until Tuesday or Wednesday.
@@2STROKESTUFFING Happy Birthday in advance of Tuesday !!
...could cylinder filling issues be from the transfer passages mostly all being well curved and so the inside/innermost surfaces of each passage are fluid stalling from the tighter inner curvatures, into outerfaces smoother flows & killing port speeds with induced port flow turbulence/resonances ?
...and perhaps too much tapering along the transfer ports length, bottlenecking the port Venturi effect away from higher speeds and shorter times to flow enough ?
I am just guessing/guesstimating though
@@2STROKESTUFFING happy birthday man... I hope all your wishes come true... Can't wait to see the next video... And some big HP numbers pop up on that laptop screen 👌👍😁
@@2STROKESTUFFING Happy Birthday for Tuesday cheers.
Yep keep needle middle clip cos remember main jet works from 1/3 throttle to full by lowering clip you fatten fuel at 1/3 throttle also which can create more problems. So best to fine tune main more than needle or go for better tapered needle to hold fuel at half throttle start of power band , but I feel your needle taper is fine go as you said 125 .
Extend the pipe (primary) once you get first dyno reading , you'll be surprised what 6 inch extra length will make to topend power curve , your new twin pipe motor has longer primaries
Love it Alex well done
Cheers
How many rpm do think the engine will make maxed out.
this quest of yours to build the fastest 50cc motorcycle has more ups, downs, twists and turns than any rollercoaster i've ever been on. good on you for never giving up!
The audio does a fantastic job of picking up the difference between the 115 and 120 jet change top end difference. Now you can really hear it "open it's eyes" a bit.
If you tune engines long enough you will be able to hear exactly what it's doing and what it wants.
@@nallen1006 what valve
You are one of, if not the most, ingenious men I've ever had the pleasure of watching. Your work is mesmerizing and quite honestly I've never seen anything quite like it in my 40+ years of small engine mechanics. What you are able to do with only a screw driver, pliers, and a piece of aluminum is beyond amazing. Your videos are captivating with each one comes a sense of wonderment and by the end I'm left dumbfounded and anxious for the next one. You are without a shadow of doubt a wizard of blue smoke and master of 2 stroke! thanks
"Wizard of blue smoke, Master of the two stroke!" needs to be a t-shirt.
Well said!
God damn bro, you gonna swallow too?
Screw drivers, pliers and heavy industrial machinery....
Mike Patey is also interesting to watch
2SS Video day is always my favorite day of the week. I've made more progress on my projects since I started watching your videos than in the several years before. Thanks for the motivation man. Easy really isn't worth anything.
Thanks man!
It was great to hear this thing run through the gears even if its not 100% yet. Excited to see what happens next!
Even running badly, it still sounds fantastic. I can't wait to hear this beast going hard!
Great to hear it singing through a gearbox after all this time!!
Man, I love that you shot this video in 21:9. It's honestly refreshing to see a youtube video that actually fills the entire screen of my ultrawide monitor. This also looks good on a normal 16:9 monitor since it gives that cinematic effect with the black bars top and bottom when full screen. I'm just happy that for once, I actually get to use all of my monitor in a youtube video in full screen lol
At the age of 17 I owned a 50ccm Suzuki ER. I put on a 76ccm 11hp Malossi cylinder with 20 mm Delorto carburator. The exhaust was either Malossi or Gianelli. This rig did well but me and my friends always wanted more so we customized and experimented a lot. We created larger exhaust ports, made new fueling ports including new transfer windows in the piston. All this gave more power. I decided to take one of my engines and create a high rpm monster by reducing the crankshaft weights and install high rpm crank ball bearings. This was something I could do at school where I had access to a lathe. With this modification I got more rpms but less torque. I am a big an heavy guy so the change did not do to much for me. I later sold the bike to a much smaller guy and with him the bike became the monster I wanted to create. He got crazy speeds with it. This was now 30 years ago. I time I will always remember. I loved every moment of it. It's so cool to follow you channel and I love that you share your journey with us. Keep up the great work Alex. We all root for you.
Every Friday I'm here with my coffee and smoke, makes my Friday morning. :) Keep up the good work, love the videos. :)
What a roller coaster of a journey this is
I love how this gets posted 20 minutes before Im getting ready to take my shitbox puch out for a long ride after finally getting it back together and running smoothly. Gives me a good feeling still bringing extra plugs and a tool kit
Untrench the crankcase. Smaller diameter transfer ports. It will give more pressure on the downstroke charge. Too much takes away from a complete cylinder charge. My thoughts. Your doing good Alex and thanks for sharing. Your going to be a big star at the salt flats. Cheers from Morrison Colorado.
Aprillia rs50 the most wonderfull moped ever ive driven one for years when i was younger tuning it fixing it it has teached me so many things about 2stroke engines that i began to fix them to earn money hehe
Been watching your videos for a few years now, as a two stroke enthusiast myself (mainly small bore Motocross) and engineer also you never fail to amaze with your knowledge, aptitude and willingness to tackle any task.
Keep up the great work you're doing 👊👊👊
I do appreciate the ridiculous amount of time you spend editing the cuts to match the beat of the music.
It's pretty fkn sweet.
Holy crap the way it sounds through the gears ❤️❤️❤️
Im hyped , keep it up moments like these are the reason why people continue with engineering.
Im watching this in the future... you find the answer to all the strangeness in the end. You nearly got it here. Great perseverance my friend.
Come on everybody, Happy Birthday Alex Charity-Drive! 🎂
Donate $1, $10, $100,000,000 whatever you have! For the birthday of the boy!
Even if it's just 1000 people donating $1 each that's still a heck of a lot! Let's give him a big birthday surprise!
It's so awesome to finally hear you banging gears. Love it.
Happy Birthday 🎉
Thanks Alex, that was truely fantastic. You have a massive smile on your face now!
Remember the episode "Should you go this fast on a bicycle?", yeah you should. At least more often. Im craving a road test every now and then. *Dreaming myself back to the young days*
It may seem to you that I am far from the truth, but there are several problems in the engine:
1) The top dead center of the piston is very high
2) The resonator does not cope with the gases supplied from the engine
3) Chain tension needs to be better balanced
4) The speed is not bad, but the torque is rather weak, possibly due to insufficient compression, the culprit of which may be both the rings and the quality of the deposition in the cylinder or the lack of weight of the cylinder
OMG when you clutch kick it and the rpm just goes 🔥🔥 best moment ever
The epic music was very well placed. Like a detective having an epiphany as to who the person was and how they got away with it……
Excellent, dunno about others, but theres something in the way you do your presentations "narration" that has an addictive feel to it, your positive attitude through the highs and lows,seems to carry that forward ,and will no doubt carry you on to success.... Cheers
You should lol up "rides of Japan". They're both artists
Suzuki LT 80 quad had a fan pressureizing the air box seemed to work well
Proud of you. Been following your progress since you started posting vids. Fantastic work.
It’s running good now! An EGT sensor in your pipe might help you when you’re troubleshooting fueling. There’s a lot of resonance in the long belt run from the case to the transmission.
A lambda & MAF sensor and a stand alone ECU might also help. (I'm not sure why electronics are being rejected).
@@StrikeEngine The problem with all the added electronics is the mass complexity. It all takes time away from building. This engine is unique so you have no data to go on.
When Alex lowered the crankcase volume there was more progress made there than any time in the past 18 months. Fueling is only one small part of this puzzle.
The high revs that Alex is searching for is the stumbling point. Zero to 20k takes a lot of doing on a experimental engine.
@@StrikeEngine o2 sensors die VERY fast in 2 stroke applications due to the oil that's added to the gas.
@@StrikeEngine I do wonder why it's not on EFI. Not like it's a V12, you only need wiring for one tiny injector and a few sensors. Negligible added complexity, almost zero chance of going wrong once it's set up right as there's so few wires. He could just rely on MAP/MAF, no need to bother with O2 if it doesn't work as well with 2 strokes. You only have to get the volumetric efficiency and injector data right once and make small tweaks from there based on logs, seems like it would save a lot of time compared to messing with carb jets for inevitably inaccurate, inconsistent fuelling (with all the servicing and tweaking entailed). On EFI it would gain a bit of power, idle better, better responsiveness etc.
@@JamesBalazsyeah any kind of engine can benefit added power, reliability,and easier tuning from injection, wether it's port direct or both. if there is indeed something special about small displacement fast revving two stroke , then at least a smart carb sould make things easier
Never give up. We are with you every step of the way, through victories and blunders.
You are now better stocked than my last profficcinal machineshop job .
Your vids are always a treat on Fridays
I'm just mentioning it, you can buy reinforced sim rings that can withstand higher pressure, they are used for hydraulics etc.
When doing this loud kind of loud bike stuff I made an enormous silencer out of a 55 gallon drum with baffles,old rugs etc. The neighbors never knew I was tuneing the worst sound known to mankind. I love your videos.
With the background music at the end and the birthday in the middle, this hyped me up a lot. 😅
Have a great birthday. And we will wait as long as it takes. You are the man of cliffhangers.
HAPPY BIRTHDAY MAY 2 ! I’m on the 3rd knew there was a reason I liked you !
Looking forward to the next video, hopefully this is really the answer and it finally gets its wheels rolling on the road.... Can't wait to see how fast this thing is, it looks so good in that frame too. Happy Birthday and see you next time.... 🎊🎂🎉 😁👍
So close to an actual road test really exciting
"Reodor Felgen" is a much loved character based upon a mechanical genius character in the Norwegian Award Winning animated film: The Pinchcliffe Grand Prix (Flåklypa Grand Prix).
Alex here, must certainly have gotten a lot of compliments & comments for his uncanny resemblance to this beloved character. Movie comes highly recommended for ALL ages...
As a Kiwi it's a very proud moment to hear you reference the Britten. I was lucky enough to sit on one back in 95. Love your style Alex keep doing it.
Just look at that RS50 frame - no manufacturer is putting effort into under 125cc machines anymore… the Chinese are nailing style but even the Japanese are recycling boring designs from decades ago with the main focus on 4t clean burn tech.
The Aprilia RS range is just mind blowing and other manufacturers around that time were doing crazy things
It’s truly sad that the focus is on EV these days and 0% focus on race reps
Happy upcoming birthday Alex enjoy the day and swich off for a bit.
Happy Birthday for Tuesday!
This is a BIG step you made here, congratulations!
It's coming together; it's inevitable.
🤩
Looking forward to the next episode! :)
Have a happy birthday and your eureka moment is correct.
Holy s...! I'm having a birthday at 2.5. and turning into 40. Massive fistbump! Just watching this video a beer in my hand and contemplating my hungover at wednesday. So happy B-day to you!
Happy birthday then! Im two years behind you.
@@2STROKESTUFFING You will start catching up mate, now I decided to start counting backwards.:)
@@Kostamovaara I'll never grow up, regardless of my age😂
@@2STROKESTUFFING likewise my dear Norwegian crazy (engine)doctor.. likewise
I so want your eureka moment to be my eureka moment with this build. It's messing with my melon man.
Then, once you've smashed this project out of the park, we need a moto 3 engine that wins grand prix 🤞🏻
This is both a huge jump forward visually for us viewers but also for all the problems it has solved and opportunities it has created!
The packaging on the Aprilia looks so good for this engine. No more fuel aeration or dyno drive issues. We get to see it on the road performing!
Ok, the next 3 or 4 days are going to drag on forever. I can't wait to hear your explanation. Thanks for the suspense!
2 stroke stuffing...less filling...less transfer losses
"That's extremely poor fuel flow..."
Your photography director is a genius ;) Im in love with that frames, colour and compositions.
I hope so!!! Best of luck and happy birthday!
Have a great birthday and come back refreshed !
I'm just enjoying the ride as he slowly descends into madness.
Really appreciate the aspect ratio on this one 😊
The pain after so many months I can't imagine how it must feel to be so close now. Keep up the amazing work we are all look forward to the next installment 👍👏🤞
bro its soo nice seeing u stick with it and working out the kinks!
Sometimes I think I can slightly understand the chaos that swirls in your brain Alex..... I cannot wait to see where you are going with this eureka moment.
some place where no man has gone before ..the total uneducated guessing zone of complete failure , kinda like an alcoholic who keeps making the same mistakes looking for better results ...i wonder if he knows the most powerful 50cc motorcycle holds the record at 150 mph
In this until the end, Alex. Keep going. 👏👏
The best thing about fridays is 2SS videos ❤
I will say Happy Birthday now, I will forget by Tuesday. Great videos. 😃
nothing beats getting hit with a ton of bricks when you've been searching and searching for the problem(s).
also, this is starting to remind me of saturday mornings as a kid, gotta catch the new episodes of cartoons!
Again, excellent musical accompaniment!
These videos are always interesting, often exciting, but now that suspense is just straight up killing me!
My brother turned and cut his own posts and fitted cbr600 selector folks, a alloy precision drum a taller 6th to his am6 gearbox. That helped with the false neutrals😉
I would print that thumbnail and hang it on my wall!
This cinematography is a work of art. Regardless of the 2-strokes
Really good episode, this one! Excellent editing. The music really fits the atmosphere, and you can feel the good vibes. So stoked about your revelation and your fix, hope it works!
O dear god you are gonna build the most powerful engine ever for sure
Happy birthday!! We can wait to see the outcome!
The sound of the water being poured into the cooling system was strangely delightful! Does this mean I'm weird?
I love how the german simson tuning community is supporting you
Yeah can’t say enough how satisfying it was to watch and listen to you make noticeable progress with tuning in just one video. That had to have felt good 🎉 my favourite channel on TH-cam ❤
Happy Birthday from a fan in Canada!
Great to see the progress and very gratifying to see you’re getting more outside support. One thing that always frustrates me is that you nearly always change more than one thing at a time. While I do realise that you have TONS of detailed knowledge and understanding, I can’t help but think that changing only one thing at a time would ultimately result in faster progress. After all, it’s all about reducing the uncertainty. You do you, Alex. I’m just saying. And I hope you have a Happy Birthday on Tuesday! Try to forget the project completely on that day at least and be totally present with those who love you. Obsession is a relentless mistress. And sometimes she needs to be put in her place. Have a great day on Tuesday! 😊👍🏻
Happy birthday dude! All the best wishes from germany!
Happy birthday in advance! Can't wait to watch the next video!
man, 2 stroke revving really high rpm sounds awesome
Oh! the suspense is defening. Have a great birthday.
Perfect timing as always!
It turned out to be much too advanced 😁
@@ferrumignis lol!
I believe there are losses in that belt drive marrying the two engines together, vibrates excessively at high RPMs... which leads me to believe it may be skipping a tooth every now and then.
P.S. Happy birthday, looking forward to the next episode to see what's planned.
Happy Birthday.
Congratulations dude! You've earned it
Love it, as per everyone else. Definately time to go EFI so that you can focus on stuff other than carb tuning
yeah love everything about the channel but the carb issues are really constantly slowing down he progress and filling the videos with more repetitive and less interesting material.
I can only imagine how frustrating it must be to face always the same problems, or maybe you're enjoying it so much that you don't mind ? I don't know if it makes sense but if it really has to be a carb, having a tuning carb dedicated to Dyno testing that you could alter the richness at different throttle openings and different rpms quickly with screws would be great.
@@geemy9675 Hello there, if I may just give you my thoughts.
While carburation problems have being at the forefront of Alex's video's for some time now and many people have commented that it's time for EFI. I can fully understand that sentiment.
Carburation is only a small part of the problem Alex is facing. This engine is radical in it's design which has lead to many problems that need facing.
Just look at the progress that has being made since the crankcase volume has being reduced. I'm hoping Alex will be doing port flow testing in the next video simply by blocking transfer ducts with toilet paper to increase gas speed through the port windows.
Mark Atkinson had similar problems to this several years ago with his projects.
Can't wait no sleep this week, constantly checking The Tube for new updates from you. It's going to be a very rough week.
Happy Birthday for Tuesday.
90 psi seems pretty low. If I remember correctly most of the two stroke motocross bikes I had as a kid always pulled between 160-180 psi with the throttle fully open. I’d say your onto something with the cylinder filling.
finaly! and happy birthday Alex - from just across the border😎🎂
Got my own xr6 project brewing. Was enthralled by your work on it and found one for sale. There are only 10 left registered in the uk.
Happy Birthday for Tuesday. Thanks for a great channel..
Finally have a clutch and gearbox on the engine 😁 and being in the Aprilia means it will be ridable soon 😁😁 can't wait to see the go pro footage
Hearing the motor wrap out while shifting through the gears, put the stupidest grin on my face
Wow, now we are talking! I can't wait for the next video to see how it will run!
Also, have a nice weekend and a happy bithday Alex!
Happy birthday bro! It's a crazy journey you've taken us on so far, and I can't wait to see the on-road testing. Impeccable craftsmanship in both mechanical and video editing as always. Stay safe my friend 🤙🏻
Happy Birthday for Tuesday, from Australia.
Hey friend, I think we've reach a point in this engine where I think it safe to say there is a need for a redesign of the engine crankcase to now house the gear box to create finally engine assembly
The engine setup just sits there perfectly.
Edit: Advance Happy Birthday to you man!!🍺☕
