This is one of the very few things that I can actually justify supporting on Patreon. I've been a patron for few years now, and have no intentions of ending that. Keep at it, man. I don't even care about late videos and whatnot. We all have lives that take time from other things we want to be doing.
Eh, dropped support last year after the lengthy and frequent drop outs. I get up and work 10-16 hours in the field on heavy equipment 5-6 days a week. If I have to work for my food money, he has to work for my content money. Basically has dropped down to doing maybe 2 full days worth of work per weekly vid. Just doesn't cut it for me. Especially when 10% of the video is an ad read. I'll keep watching and might pick support back up if full effort regular uploads start back again.
Watching your channel is NOT about a result, but the way you are taking to get there. I enjoy every little misstep and smallest success equally as the way you are presenting your progress in this very special format makes me love watching every single episode. Do not get stupid about things taking longer than expected, allways remember that all of this was never done before or even If it was, there was no cameras archiving it. I know how you feel, but please try to just continue as if everything was fine. Because it is and allways will be ❤
Keep at it man! I can honestly say that you have the only channel I haven't missed viewing a single video on. Life, personal issues etc get in the way at times... nothing you can do but take care of yourself and your family, we'll still be here. I believe you have an unusually loyal following that won't go away. Great content as always. Best regards from Sweden.
This is 100% the only channel i really look forward to seeing a new video everytime! I feel for your struggles aswell, i had a bad year last year, but now things are getting better, and i want things to get better for you as well! Greetings from neighboring Finland and good luck on everything!
"Slow and steady, wins the race"... A saying that works, especially with projects like this. WE'RE ALL WITH YOU Alex. Keep on keeping on, we all believe in your dream, your plans, and your hopes for what this mighty little motor is capable of. So, stick with it kiddo, and all the very best to you and your loved ones! 🤞👍😏 😎🇬🇧
congrats on the 200k subs! can't remember when I subbed but I think it was before 100k or so. keep up the good work, and no stress, I would rather wait a few more days og even weeks for it to be done right.
Just stumbled upon this channel and decided to give it a view, I love the way you meticulously address all inpuit given about youre approach and results. Then i read some comments and youre subscribers and long time viewers have given you some of the most grateful whole hearted reviews. I am honestly happy to see support of this type and words of encouragement. What you are doing will one day inspire someone to push the limits of innovation
I have peole around me that Im aware of and they are all quitters, "Oh no matter what I do I cant get X to happen" or "why cant i just have a stable X". Whereas this channel is the opposite and pure talent and brute force enables such enjoyable content for me, regardless of the result, its refreshing for me to see like-minded people go all out trying.
It LIVES!! Sounded really good, hopefully you can get this rendition to give you the results you want, but even if it doesn't don't get discouraged! This has been a super fun project to watch and if I get dug out of the little financial/mental health rut I'm working through right now I'd happily do what I can to support your channel so we can keep the progress going. I definitely know what it's like to be supporting a household and having 1,000 things outside of that that you want to finish up but money is tight. It definitely weighs a guy down sometimes but we'll get it done. You're doing a great job!
Hey Alex. Don’t worry.Slow and steady wins the race. The more videos you can put out will make us all a lot happier as viewers and hopefully take some of the pressures you imagine off you and your family. Cheers from down under.❤❤
Of course I keep my patreon going for you Alex. Great stuff you are doing here. Always something to learn and lots of eyecandy for any petrol head. Keep up with what you do its ecxatly how it needs to be.
I watched your channel regularly a couple of years ago. Then I had my doubts and I watch it maybe once every 6 months. Progress? Is there any? Yes, a nice video format, but not much else. Maybe I should check again in a year or two.
Went and got a water bottle man! ,been needing one for awhile. Take your time ,well always support you along the way ,if you're worried about getting videos out ,some lower effort garage tours ,or looks at old projects are always appreciated
You could also change the brake master cylinder for one with a smaller diameter piston. The piston size is usually cast into the mc body. I was going to suggest changing the lever ratio, by moving the fulcrum/ pivot point closer to the piston, but I’m unsure how you could do it.
Good job ,it sounds crisp like your a little lean for a break in period. They sell in line thermostat housings but I'm sure you could make one with all the tooling you have. Two strokes like some heat to close up the tolerances , you won't crystalize the surfaces for break in without some proper heat in there. I like to run about 10 heat cycles on a new engine before give it any real abuse. Running a little rich during this time helps the parts get used to each other and keeps plenty of oil between the parts as they create "their" new tolerance for eachother. Without enough heat the parts will crystalize the surface without effecting the core of the parts. After heat up and cool down cycles I give it a new plug and then jet for power. I'm too poor to give you money but good advice will save you a fortune.
Many many years later and im still here, we all have life's and family's and your true supporter's will understand this, keep up the good work brother.
I've been following you for a really long time . Today I became a patreon because I really want to help you stay focus on the Dream ! Life is hard, but easy is not worth anything 💪
I have same plan for Brake dyno for my engines I have Briggs v-twin 480cc and small 49cc from my moped. I want to add pressure for calipper with bolt or something with consistent pressure because, using hand cant be consistent at all. My second idea is using hydraulic pump and measuring pressure and flow of oil. There can be anything, for ex. used engine oil from gasoline car. offcourse using filter before pump. With this system, you can tuning you engine for long time because dont get red hot after few runs. Also hot pads brake differend.
I just like to see the journey, I'm currently building and engine myself to make more power, a Volvo b230/2.5L it's not done in an instant and there is a lot of similarities with the approach that i've had with my engine. i've gone thorugh cycles of mine working, then not working as i want it too, finding the weaknesses or something I'm not happy about and figuring out a solution to it. So this helps a lot with motivation, takk!
F$%k that, I dont think I could handle having my income bound to an algorythm that is constantly changing and never communicated. I truly thank you Alex for the videos, they are inspiring, your passion and humbleness shows through. I even watch the Nord VPN crap just in case you get further support if I dont skip it. Youre not alone, covid made most of us feel helpless and brought anxiety that we never experienced before. Thank you again for your videos.
It's just the time of year, just surviving the winter is no mean feat. We just take it for granted, but just imagine you lived in a gama or a Lavo. I think a lot of Norwegians work too hard in the winter and get depressed when spring starts to rise and they haven't got energy like nature has. Relax a bit in six weeks everything will seem different and easier. All the best Lucas, and feel free to drop by if you are over here.
I've noticed that about some 2 strokes that they seem not to be able to handle going without a load. But since I don't run or tune them, I have never really dug into what causes this. I do know that without proper loading on the cylinder, it somewhat becomes like an un-crimped shotgun shell though. As in it will lose all its pressure before it can get a good burn, and this leads to unburned propellant spewing out the end. Could be the same thing. Could be that without some pressure to hold the combustion at its peak combustive pressure, the fuel may not want to burn completely for some reason, and that may lead to it surging, or stuttering.
When hobbies become jobs - it's a huge challenge to make the trasnsition. This is why when a hobbiest - aka a customer comes into a shop - the eagerness to work late and jump through hoops is not there. Resentment builds easily - and you have to find a way to stay passionate about what you do - without letting the job aspect ruin the fun. Utimately - I believe it's discipline that makes the difference. Set a schedule - keep the schedule - and act like you have a boss and job that will fire you off that schedule.
I hope he reads your comment. I think you really hit the nail on the head. It has seemed that his state of mind has been struggling alot since he quit his job. I agree that making a work week schedule to have to follow will help out. Unfortunately when hobbies become jobs the drive to make time for hobbies goes away. I hope he gets it figured out. I miss the excited 2 stroke stuffing.
You're right HP! For a while now I've been thinking that Alex was happier working at his engine development program when he was employed at the kindergarten. At least he could dream about what he was going to do when he got home and into the shop. Now, when he's having a bit of difficulty, he wakes up with "Oh s..., I've gotta do something in the shop this morning...", or some such negative attitude. He might reconsider his current position and look for the security of an outside job.
I was concerned about this happening when I went full time, but it's not what's been going on. I could spend hours explaining, but in short; Somehow got stuck in fight-or-flight mode, resting heartrate constantly at 100+bpm, endless stream of negative thoughts, any attempt at focusing on engine stuff got drowned, struggled to sleep. This went on for months. Was extremely tiring. Luckily I slowly got back on track, still a bit "hungover" from it all. I'm so thankful you guys stuck with me!
Life is hard - we all go through it and I've been there and at times still am. It's hard to relieve stress with a hobby that is a insurmountantable mountain at times. I suggest finding some mindless physical work, such as cutting the grass, or something that requires zero analysis just meanial work. There is something incredible valueable to accomplishing a task you can see you accomplishedthat requires no brain power. I am sure you have a life away from what is shown on yuotube - but if you love riding scooters and motorcyles - and no longer do - get a stock one you can just ride sometimes and leave that one alone...to be ridden whenever you want without headache. We will keep watching - and sooner or later - you will hit on some ideas that work good.@@2STROKESTUFFING
@2STROKESTUFFING you would know better than us. Only going off what you show us. I enjoy your videos but I also want to see you get better. Your health and family should always take priority. Get better man. We will all be anxiously waiting.
I've watched a long time and had a few different youtube accounts.. but man in the engine development world we constantly break,break, and break parts but eventually we figure it out and those ppl that hang onto the idea and fight for it thrive in the end
Chasing the dream brother. Theres a whole stack of steps and slopes to hurdle. Motivations a mind killer. Im in the same place but with 3D printers. I have it all ready to rumble but getting the motivation after several lorry driver mind confusing moments with the board control side firmware on a duff so called upgraded control board, It lowers the motivation, I even took it to a shop, who took 6 weeks and 3 different technicians to get it to work (for three prints then it went wrong again) Im not as skilled as them but im learning what doesn't work.... so eventually.... lol. Keep it going bruv.
Maybe the cutting out under throttle thing could be fuel droplets condensating on the cold surfaces of the crank case and causing misfires when they get blown to the sparkplug. My old moped does a similar thing when cold, but it clears out after it warms up a bit.
If the coolant (assuming its just water) takes too long to warm up you could just boil a few kettles and pour that in right? Should give you ~80-90 degree temps to start with.
Sorry I can not help with any funds but I will enjoy watching and recommend the video to the few friends I have still who might be interested in this stuff. Thank you for the videos and bringing us along for the journey.
instead of a twist throttle wouldn't it be better to to make the brake lever one a lever to control throttle? that would/could free up a hand. also, would adding air to the brake line make it have a little less aggressive onset? chain didn't look happy when the engine was running.
Enjoy watching you try things. That's how you learn. I was wondering why you used your monitor as a hang board for your throttle holder. Good way to wreak your monitor. you might think about that in future videos. Kind of like using a CD drive as a coffee cup holder. Keep up trying new stuff.
Hello from Sweden! I've been enjoying the content a lot! It feels as if the tide is turning, in a positive way! Great success is on the horizon! Sent over a bit of cash to help you out! Take care and let's make this one the best yet! 😊👍
The steel sleeve has made it a totally new engine..Starting over from scratch..I'm wondering about "cylinder creep" since locating bosses have been removed??..👍🗽🇺🇸
I look forward to every new video but it doesn’t matter if they’re not as regular as clockwork, it doesn’t matter if they’re exciting, we all just love watching. Keep up the good work, keep positive and I’ll look forward to the next one 🙂
Have you thought about maybe using a thumb throttle like all atv's use? it might mean that you can have the throttle control and the brake on the same lever and still only use one hand to control them both.
Try heating the jug some, and put the pieces you made into the freezer. Between the expansion of the jug, and the inserts shrinkage you should have no problem fitting them inside the transfers PS Have you ever taken into consideration that the engine is fully coming up to optimal temperature as far as activity checking the temperature while running at speed?
I have been enjoying your videos for a good while now and I look forward to each new one. One day soon, I will be binge-watching everything from the beginning. Does liking those older videos help with the algorithm or anything? I’ll do it either way, I was just wondering. I don’t know what the future has in store for this engine, but the “Supercharged Nitro Methane 50cc Two-Stroke” title of an older video hooked me and I hope to see the return of forced induction (perhaps adding a turbo to recover losses from the SC like some of the auto racing folks do) and nitro methane some day. Regardless, I will be a lifelong subscriber and fan. I have read every comment on this and about two dozen other vids of yours and I can see that support for your project outweighs the comments by sorry bastards with nothing better to do than criticize by orders of magnitude. So, I feel confident in saying we will be right there, rooting for you, cheering success, analyzing failures for clues, offering suggestions (good, bad, crazy, and hopefully some brilliant ones), and understanding when Life rears up and takes priority. We want to see new vids, and we want to see the most awesome 50cc two-stroke ever to shriek through a dyno run. But most of all, we want to see you healthy, happy, and enjoying life. Take time for yourself, your family, etc. and know that by doing so, you are making your fans happy, not letting us down. Thank you for sharing your dream with us.
Why don't you use a Temperatur control device like on motorcylces or cars? So that you have 2 coolent rings on small one (only cylinder is heating) and when it get's warm it opens up the big one to let all of the coolant cirle through the engine
Mabye running a normal cooling system from like a Derbi 125 with a termostat etc would be better. At least from my experience working alot on mopeds, cold engines never behaves "normally"
You might put a little air in that brake line to make it less sensitive. I've heard of Motorcycle racers doing that to their back brakes. Doesn't cost anything to try.
Quite right! I used a similar set up on my 50cc test engine. Once the brake pads heated up they began to snatch. Spraying WD40 onto the pads stopped the snatching, considerably more pressure was needed though.
Need to make a knob on a threaded rod to push the master cylinder. With a half nut for quick release. Yoy you can just turn the knob to get a consistent load on the break. Yes, lots of work when the end goal is a water break. But whats another side project. Without consistency, the load cell will be all over the place. Sorry about the financial stress. I bet it's overwhelming at times and then what yoy say is lack of forward movement adds even more. I know like most of us, we are with you. Just keep moving. We are all here because of 2 stokes and you. So stay at it.
You are on par with Project Binky. You can make videos at any point, and i will watch it! Chin up (an English saying that menas keep going) and do your thing!
When I used a similar system to this with my tuned 50cc test engine I spayed WD40 onto the brake pads to over come some of the fiction. More pressure was needed but it helped alleviate the snatching when the brake pads got hot under high pressure. It would be beneficial to run the disc in water but not practical.
Random comment / question about heat expansion from someone who doesn't know much about this... I believe plastics expand a lot more due to heat than metals. Would this cause any changes or issues as the engine heats with the inserts expanding and deforming?
Why not just use a alternator for the Dyno? Connect a load to The output, snd use a simple brushed motor controller connected to. The brushes. Crank up the power to the brushes/field coil for greater load , even a twist throttle can be used to apply load as you apply throttle. Get resistance wire submerged in water. As the load. Use two or more with less resistance, as a fail safe, to prevent over revving. Say the main coil is 48 turns, make a secondary about 54-56 turns thrn a third about 60+64 turns, of roughly 14 gauge resistance wire. And using a 100 amp alternator, with a 12v brushed controller to the brush, at full power its going to do about 200 volts, without load minimum, i have heard over 1000. Say the load is optimized for 16-36v thats 3600 watts being 60% efficient thats easily a 5-9 hp load, with overdrive it can require more power to spin it. alternators ste designed to operate at high rpm. 6000-8000 engine rpm, with a 3:1,4:1 overdrive with a 50 mm driven pulley, and 100mm drive pulley, at 20k rpm you may start to tax the alternator with constant sudtained speed, id definitely lube the bearings.. using two 150amp alternators would be plenty, unless you plan on. Producing over 50 HP. A chain drive would eliminate any chance of slippage , a large series wound forklift motor can be used in the same manner for an excess if 6-8 kw load. Only the rpm is lower, the rotor is limited to about 5k rpm so the pulley be would require reverse ratio, a 2:1 under drive getting a 10 k rpm engine, so a 200 mm driven, with 50 mm drive, to allow near 20k rpm engine , and the hp required to for full output. Being a 8 hp with the Peake braking being near 80 hp+, its going to require a cooling blower added to the motor/generator, if 8 hp is exceeded, a 24v 10 amp pwm motor control may be enough, with a resistive load capable of 200amps plus, it is nearly the same as how electric pallet jacks were taught to be used, corking it, using reverse to slow them to a near stop . Or forward to slow from reverse. Using the motor as generator. But alternators are cheap, china makes Delco style replicas, the 10si and12si alternators are the most popular and modified in the us. Amazon has them for less thsn $100, the si series is best, thr cs are known to fall spart, and if you want to build parts , you can build twin alternatirs in a single case, use two front case halves, to allow use of the large roller bearings. This requires making a new rotor shaft, pressing on the slip ring, and the field coils. Id use two slip rings, with the wires running inside the shaft. Under the first slip ring. Use onewhole ring ad pos+ snd thr other two ad neg- if possible, then 3D print a double brush holder, for two - and two +, per slip ring, 180° across from each other. Attach the brush holders to case. And have the rotor dynamically balanced. With the pulley or sprockets on it. Having a shaft out both ends can alliw another load added to the system easily. With two staters, having two 3 phase outputs, id make 6 equal loads with two 5 gallon buckets with water slowly circulating, connect thr 3coils together, with 3ac connections, perbucket, use a 50 gallon drum to hold the water, and a pump pulling from the two buckets, filling the drum , spraying into the drum, the drum overflow into the buckets . Keeping them filled at the same rate emptied. This should require hours to heat to the point of water loss! And total cost just running two alternators as loads roughly $220 , you can use a signal generator, a mosfet gate driver, and a couple MOSFETs, capable of the load and voltage , a capacitor, and diode. To create a dimple motor pwm controller, to regulate the load. But you can buy one for $20. The field coil resistance needs to be tested , to figure out the current it will pull at maximum voltage, get a controller capable of 25% to 50% higher current, or even double the current, volts x amps = watts, to help find a controller rated in watts. 12v 250w minimum maybe work, but 12v600 or 800watts even 1000watts, is best,but anything larger isnt common or cheap, and 18-24 v can be used. It especially with two alternators, just wire them in series. Test tge brushes are indulsted from the case, electrically. Then two 12v 6ah to two car batteries in series can be used, or a 24-30v 20 amp power supply can be used, or wire thr output to the brushes, with a high current mosfet in series it may require a 9 volt battery connrcted to the brushes to get it started, but the output will power the brushes. The faster its turned the harder it is to turn. A simple 555 timmer ic, a trim pot, snd a 12v signal to a 20 amp capable mosfet reduce the duty cycle to reduce the load on the engine. Still required the lead in water. But id rather supply the power to the brushes. It will make for low speed loads stability. Also a voltage controlled relay can kill the engine in the event the load is lost. even with a rev limmiter. Its possible to over rev when load is lost when the engine is near the rev limiter the energy in the crank and flywheel can help accelerate it past the limit if the load is lost. Possibly by hundreds of rpm. Thete being no load on the engine. Nothing to slow acceleration. Its different in a vehicle ,the transmission, wheels , a dragcar has over revved lots of times, when a drive Line breaks , with the rev limiter in place. Hope this help somehow.

Yes, he deserves it. one of the few Chanels i look for years without skip one episode. never skip a second. I also started to be a patreon right now.
Same here.. This is the only channel i support through Patreon.
Same here 😊
Yup, same here!
Eh, dropped support last year after the lengthy and frequent drop outs. I get up and work 10-16 hours in the field on heavy equipment 5-6 days a week. If I have to work for my food money, he has to work for my content money. Basically has dropped down to doing maybe 2 full days worth of work per weekly vid. Just doesn't cut it for me.

Mate i appreciate you and the project. This is a weekly treat for me watching you figure things out and bounce back from failures.
You could also change the brake master cylinder for one with a smaller diameter piston. The piston size is usually cast into the mc body.
I was going to suggest changing the lever ratio, by moving the fulcrum/ pivot point closer to the piston, but I’m unsure how you could do it.
Good job ,it sounds crisp like your a little lean for a break in period. They sell in line thermostat housings but I'm sure you could make one with all the tooling you have. Two strokes like some heat to close up the tolerances , you won't crystalize the surfaces for break in without some proper heat in there. I like to run about 10 heat cycles on a new engine before give it any real abuse. Running a little rich during this time helps the parts get used to each other and keeps plenty of oil between the parts as they create "their" new tolerance for eachother. Without enough heat the parts will crystalize the surface without effecting the core of the parts. After heat up and cool down cycles I give it a new plug and then jet for power. I'm too poor to give you money but good advice will save you a fortune.

you've come a long way from the part time youtuber that had a day job when i first started watching. keep up the good work mate
I have same plan for Brake dyno for my engines I have Briggs v-twin 480cc and small 49cc from my moped. I want to add pressure for calipper with bolt or something with consistent pressure because, using hand cant be consistent at all. My second idea is using hydraulic pump and measuring pressure and flow of oil. There can be anything, for ex. used engine oil from gasoline car. offcourse using filter before pump. With this system, you can tuning you engine for long time because dont get red hot after few runs. Also hot pads brake differend.
I just like to see the journey, I'm currently building and engine myself to make more power, a Volvo b230/2.5L
it's not done in an instant and there is a lot of similarities with the approach that i've had with my engine.
i've gone thorugh cycles of mine working, then not working as i want it too, finding the weaknesses or something I'm not happy about and figuring out a solution to it.
So this helps a lot with motivation, takk!
Congratulations to 200k
F$%k that, I dont think I could handle having my income bound to an algorythm that is constantly changing and never communicated.
I truly thank you Alex for the videos, they are inspiring, your passion and humbleness shows through. I even watch the Nord VPN crap just in case you get further support if I dont skip it.
Youre not alone, covid made most of us feel helpless and brought anxiety that we never experienced before. Thank you again for your videos.
It's just the time of year, just surviving the winter is no mean feat. We just take it for granted, but just imagine you lived in a gama or a Lavo. I think a lot of Norwegians work too hard in the winter and get depressed when spring starts to rise and they haven't got energy like nature has. Relax a bit in six weeks everything will seem different and easier. All the best Lucas, and feel free to drop by if you are over here.
«Well take things a little carefull» proceeds to bed in everything at an easy gazillion revs🤣 love it👍🏻
Yes - good to have you back..
I've noticed that about some 2 strokes that they seem not to be able to handle going without a load.
But since I don't run or tune them, I have never really dug into what causes this.
I do know that without proper loading on the cylinder, it somewhat becomes like an un-crimped shotgun shell though.
As in it will lose all its pressure before it can get a good burn, and this leads to unburned propellant spewing out the end.
Could be the same thing.
Could be that without some pressure to hold the combustion at its peak combustive pressure, the fuel may not want to burn completely for some reason, and that may lead to it surging, or stuttering.
Great job, the engine sound is quite nice. You are moving fast 👍
Use a threaded rod and a nut or something similar to actuate the brake master piston. The finer the thread pitch the better it will be. Good luck!
So happy you're back and happy about it!
When hobbies become jobs - it's a huge challenge to make the trasnsition. This is why when a hobbiest - aka a customer comes into a shop - the eagerness to work late and jump through hoops is not there. Resentment builds easily - and you have to find a way to stay passionate about what you do - without letting the job aspect ruin the fun. Utimately - I believe it's discipline that makes the difference. Set a schedule - keep the schedule - and act like you have a boss and job that will fire you off that schedule.
I hope he reads your comment. I think you really hit the nail on the head. It has seemed that his state of mind has been struggling alot since he quit his job. I agree that making a work week schedule to have to follow will help out. Unfortunately when hobbies become jobs the drive to make time for hobbies goes away. I hope he gets it figured out. I miss the excited 2 stroke stuffing.
You're right HP! For a while now I've been thinking that Alex was happier working at his engine development program when he was employed at the kindergarten. At least he could dream about what he was going to do when he got home and into the shop. Now, when he's having a bit of difficulty, he wakes up with "Oh s..., I've gotta do something in the shop this morning...", or some such negative attitude. He might reconsider his current position and look for the security of an outside job.
I was concerned about this happening when I went full time, but it's not what's been going on. I could spend hours explaining, but in short; Somehow got stuck in fight-or-flight mode, resting heartrate constantly at 100+bpm, endless stream of negative thoughts, any attempt at focusing on engine stuff got drowned, struggled to sleep. This went on for months. Was extremely tiring. Luckily I slowly got back on track, still a bit "hungover" from it all.
I'm so thankful you guys stuck with me!
Life is hard - we all go through it and I've been there and at times still am. It's hard to relieve stress with a hobby that is a insurmountantable mountain at times. I suggest finding some mindless physical work, such as cutting the grass, or something that requires zero analysis just meanial work. There is something incredible valueable to accomplishing a task you can see you accomplishedthat requires no brain power. I am sure you have a life away from what is shown on yuotube - but if you love riding scooters and motorcyles - and no longer do - get a stock one you can just ride sometimes and leave that one alone...to be ridden whenever you want without headache. We will keep watching - and sooner or later - you will hit on some ideas that work good.@@2STROKESTUFFING
@2STROKESTUFFING you would know better than us. Only going off what you show us. I enjoy your videos but I also want to see you get better. Your health and family should always take priority. Get better man. We will all be anxiously waiting.
I've watched a long time and had a few different youtube accounts.. but man in the engine development world we constantly break,break, and break parts but eventually we figure it out and those ppl that hang onto the idea and fight for it thrive in the end
you got this man!
Chasing the dream brother. Theres a whole stack of steps and slopes to hurdle. Motivations a mind killer. Im in the same place but with 3D printers. I have it all ready to rumble but getting the motivation after several lorry driver mind confusing moments with the board control side firmware on a duff so called upgraded control board, It lowers the motivation, I even took it to a shop, who took 6 weeks and 3 different technicians to get it to work (for three prints then it went wrong again) Im not as skilled as them but im learning what doesn't work.... so eventually.... lol. Keep it going bruv.
Maybe the cutting out under throttle thing could be fuel droplets condensating on the cold surfaces of the crank case and causing misfires when they get blown to the sparkplug. My old moped does a similar thing when cold, but it clears out after it warms up a bit.
Thumb screw to control the brake leaver will help be smoother and more repeatable
Best channel on youtube , content & creator are top notch
compound curves in the B port can cause turbulence, try to make it curve around, and then hook, in two distinct bends
If the coolant (assuming its just water) takes too long to warm up you could just boil a few kettles and pour that in right? Should give you ~80-90 degree temps to start with.
EVERYONE SHUT UP THE 2 STROKE WIZARD IS BACK!!!!

Glad see you back and hear that mean lil 2 stroke running again 👍
Sorry I can not help with any funds but I will enjoy watching and recommend the video to the few friends I have still who might be interested in this stuff. Thank you for the videos and bringing us along for the journey.
Nice one mate good to see your getting back on the ball and good luck
instead of a twist throttle wouldn't it be better to to make the brake lever one a lever to control throttle? that would/could free up a hand. also, would adding air to the brake line make it have a little less aggressive onset? chain didn't look happy when the engine was running.
Awsome to see you back bro!! Love the update
man I love watching these videos - and Ironically I've been looking for a VPN to use.
Thanks for uploading.
Enjoy watching you try things. That's how you learn. I was wondering why you used your monitor as a hang board for your throttle holder. Good way to wreak your monitor. you might think about that in future videos. Kind of like using a CD drive as a coffee cup holder. Keep up trying new stuff.
Just keep making progress, and don't worry. You have a huge following.
Keep going please. Your journey and content is well worth financially supporting as it is unique and world class in the RUclips and media world. 🙌
Hello from Sweden! I've been enjoying the content a lot! It feels as if the tide is turning, in a positive way! Great success is on the horizon! Sent over a bit of cash to help you out! Take care and let's make this one the best yet! 😊👍
The steel sleeve has made it a totally new engine..Starting over from scratch..I'm wondering about "cylinder creep" since locating bosses have been removed??..👍🗽🇺🇸
Gosh I am finally are a patreon...Wish it was a little easier...great to be aboard!!
I look forward to every new video but it doesn’t matter if they’re not as regular as clockwork, it doesn’t matter if they’re exciting, we all just love watching.
Keep up the good work, keep positive and I’ll look forward to the next one 🙂
Have you thought about maybe using a thumb throttle like all atv's use? it might mean that you can have the throttle control and the brake on the same lever and still only use one hand to control them both.
we love you dude, keep up that awesome work, keep the momentum!!!!!
It’s has been a hard year, but you are moving forward , never say die
Try heating the jug some, and put the pieces you made into the freezer.
Between the expansion of the jug, and the inserts shrinkage you should have no problem fitting them inside the transfers
PS
Have you ever taken into consideration that the engine is fully coming up to optimal temperature as far as activity checking the temperature while running at speed?
Legit the only channel I watch
I have been enjoying your videos for a good while now and I look forward to each new one. One day soon, I will be binge-watching everything from the beginning. Does liking those older videos help with the algorithm or anything? I’ll do it either way, I was just wondering.
I don’t know what the future has in store for this engine, but the “Supercharged Nitro Methane 50cc Two-Stroke” title of an older video hooked me and I hope to see the return of forced induction (perhaps adding a turbo to recover losses from the SC like some of the auto racing folks do) and nitro methane some day.
Regardless, I will be a lifelong subscriber and fan. I have read every comment on this and about two dozen other vids of yours and I can see that support for your project outweighs the comments by sorry bastards with nothing better to do than criticize by orders of magnitude. So, I feel confident in saying we will be right there, rooting for you, cheering success, analyzing failures for clues, offering suggestions (good, bad, crazy, and hopefully some brilliant ones), and understanding when Life rears up and takes priority.
We want to see new vids, and we want to see the most awesome 50cc two-stroke ever to shriek through a dyno run. But most of all, we want to see you healthy, happy, and enjoying life. Take time for yourself, your family, etc. and know that by doing so, you are making your fans happy, not letting us down.
Thank you for sharing your dream with us.
CONGRATULATIONS on reach $200,000 subscribers!
Head up mate. Keep on pushing. You'll get there.
good to see the engine running
Congrats on 200K subs!
Why don't you use a Temperatur control device like on motorcylces or cars? So that you have 2 coolent rings on small one (only cylinder is heating) and when it get's warm it opens up the big one to let all of the coolant cirle through the engine
Because he's trying to remove variables, not add them.
could you cut away some of the brake pad so you have a smaller surface area touching the rotor? seems like its going to be hard to control.....
Man, it sounds propple fantastic!
RC servos and a transmitter+receiver would be a great way to control the throttle and brake
When will we here it start bra 😮
Mabye running a normal cooling system from like a Derbi 125 with a termostat etc would be better. At least from my experience working alot on mopeds, cold engines never behaves "normally"
You might put a little air in that brake line to make it less sensitive. I've heard of Motorcycle racers doing that to their back brakes. Doesn't cost anything to try.
Quite right! I used a similar set up on my 50cc test engine. Once the brake pads heated up they began to snatch. Spraying WD40 onto the pads stopped the snatching, considerably more pressure was needed though.
Need to make a knob on a threaded rod to push the master cylinder. With a half nut for quick release. Yoy you can just turn the knob to get a consistent load on the break.
Yes, lots of work when the end goal is a water break. But whats another side project. Without consistency, the load cell will be all over the place.
Sorry about the financial stress. I bet it's overwhelming at times and then what yoy say is lack of forward movement adds even more. I know like most of us, we are with you. Just keep moving. We are all here because of 2 stokes and you. So stay at it.
Hey Stuffings I will watch everything you put out it's all I can do for now!!
You are on par with Project Binky. You can make videos at any point, and i will watch it! Chin up (an English saying that menas keep going) and do your thing!
Keep on keeping on Dude. Shits getting real out there - hold the line.
Put the dyno brake on a pedal maybe? 👍🏼 she’s running smooth as silk 🤩
That thing is ripping!!
Sounds ready for some boost!!!
WHAT ARE YOU WAITING FOR! For 10 years this man is making great video's. For our education! Now is the time to support a fellow oily-petrol head!
I was hoping you were planning to come back to Bonneville, any hope left for that?
When i hear the SOUND of this "just" 50ccm motor, i hear him screaming: Give me air, give me fuel and i burn the hell right out of everything😂😂😂❤
Maybe a long knee or foot controlled brake lever to free your hands and reduce the braking sensitivity could be a temporary and cheap solution.
When I used a similar system to this with my tuned 50cc test engine I spayed WD40 onto the brake pads to over come some of the fiction. More pressure was needed but it helped alleviate the snatching when the brake pads got hot under high pressure.
It would be beneficial to run the disc in water but not practical.
Those of us that have been here since the beginning are still wit cha!!
Looking forward for the upcoming videos! Very exciting
Woooo! Engine’s running!!! 🎉
Knock knock .. knock knock .. the 'Door" will open - Keep it up 💪
use your foot to actuate the brake lever
Raising the engine stand wasn't a less destructive option?
Random comment / question about heat expansion from someone who doesn't know much about this...
I believe plastics expand a lot more due to heat than metals. Would this cause any changes or issues as the engine heats with the inserts expanding and deforming?
Nice video. As always looking forward to the next one.
I think a foot pedal for brake would be better possibly? Keep up the good work bud!
hello from Brisbane Australia!
You’re doing great keep up the good work
Good news is always good!

Why not just use a alternator for the Dyno? Connect a load to The output, snd use a simple brushed motor controller connected to. The brushes. Crank up the power to the brushes/field coil for greater load , even a twist throttle can be used to apply load as you apply throttle. Get resistance wire submerged in water. As the load. Use two or more with less resistance, as a fail safe, to prevent over revving. Say the main coil is 48 turns, make a secondary about 54-56 turns thrn a third about 60+64 turns, of roughly 14 gauge resistance wire. And using a 100 amp alternator, with a 12v brushed controller to the brush, at full power its going to do about 200 volts, without load minimum, i have heard over 1000. Say the load is optimized for 16-36v thats 3600 watts being 60% efficient thats easily a 5-9 hp load, with overdrive it can require more power to spin it. alternators ste designed to operate at high rpm. 6000-8000 engine rpm, with a 3:1,4:1 overdrive with a 50 mm driven pulley, and 100mm drive pulley, at 20k rpm you may start to tax the alternator with constant sudtained speed, id definitely lube the bearings.. using two 150amp alternators would be plenty, unless you plan on. Producing over 50 HP.
A chain drive would eliminate any chance of slippage , a large series wound forklift motor can be used in the same manner for an excess if 6-8 kw load. Only the rpm is lower, the rotor is limited to about 5k rpm so the pulley be would require reverse ratio, a 2:1 under drive getting a 10 k rpm engine, so a 200 mm driven, with 50 mm drive, to allow near 20k rpm engine , and the hp required to for full output. Being a 8 hp with the Peake braking being near 80 hp+, its going to require a cooling blower added to the motor/generator, if 8 hp is exceeded, a 24v 10 amp pwm motor control may be enough, with a resistive load capable of 200amps plus, it is nearly the same as how electric pallet jacks were taught to be used, corking it, using reverse to slow them to a near stop . Or forward to slow from reverse. Using the motor as generator. But alternators are cheap, china makes Delco style replicas, the 10si and12si alternators are the most popular and modified in the us. Amazon has them for less thsn $100, the si series is best, thr cs are known to fall spart, and if you want to build parts , you can build twin alternatirs in a single case, use two front case halves, to allow use of the large roller bearings. This requires making a new rotor shaft, pressing on the slip ring, and the field coils. Id use two slip rings, with the wires running inside the shaft. Under the first slip ring. Use onewhole ring ad pos+ snd thr other two ad neg- if possible, then 3D print a double brush holder, for two - and two +, per slip ring, 180° across from each other. Attach the brush holders to case. And have the rotor dynamically balanced. With the pulley or sprockets on it. Having a shaft out both ends can alliw another load added to the system easily. With two staters, having two 3 phase outputs, id make 6 equal loads with two 5 gallon buckets with water slowly circulating, connect thr 3coils together, with 3ac connections, perbucket, use a 50 gallon drum to hold the water, and a pump pulling from the two buckets, filling the drum , spraying into the drum, the drum overflow into the buckets . Keeping them filled at the same rate emptied. This should require hours to heat to the point of water loss! And total cost just running two alternators as loads roughly $220 , you can use a signal generator, a mosfet gate driver, and a couple MOSFETs, capable of the load and voltage , a capacitor, and diode. To create a dimple motor pwm controller, to regulate the load. But you can buy one for $20. The field coil resistance needs to be tested , to figure out the current it will pull at maximum voltage, get a controller capable of 25% to 50% higher current, or even double the current, volts x amps = watts, to help find a controller rated in watts. 12v 250w minimum maybe work, but 12v600 or 800watts even 1000watts, is best,but anything larger isnt common or cheap, and 18-24 v can be used. It especially with two alternators, just wire them in series. Test tge brushes are indulsted from the case, electrically. Then two 12v 6ah to two car batteries in series can be used, or a 24-30v 20 amp power supply can be used, or wire thr output to the brushes, with a high current mosfet in series it may require a 9 volt battery connrcted to the brushes to get it started, but the output will power the brushes. The faster its turned the harder it is to turn. A simple 555 timmer ic, a trim pot, snd a 12v signal to a 20 amp capable mosfet reduce the duty cycle to reduce the load on the engine. Still required the lead in water. But id rather supply the power to the brushes. It will make for low speed loads stability. Also a voltage controlled relay can kill the engine in the event the load is lost. even with a rev limmiter. Its possible to over rev when load is lost when the engine is near the rev limiter the energy in the crank and flywheel can help accelerate it past the limit if the load is lost. Possibly by hundreds of rpm. Thete being no load on the engine. Nothing to slow acceleration. Its different in a vehicle ,the transmission, wheels , a dragcar has over revved lots of times, when a drive Line breaks , with the rev limiter in place. Hope this help somehow.
