This is the road to the most powerful two stroke (relative to cc) ever. Aiming for 30+hp from 50cc.
Lofty goal!
Here's a few key points:
- 100% bore width single exhaust port, no bridges, non. This leads to unrivaled blowdown specific time area.
- What should be excellent transfer duct geometry, large radius on inner walls to minimize flow separation, constant side wall angles for control, large duct volume for gentle "delivery"
- Valveless tuned length intake with nitromethanol injection, aimed at the transfer inlets.
- Ridiculous crankcase volume, no piston pumping here, it's all about resonance!
- Tuned pipe, tuned crankcase, tuned intake, tuned everything, resonance!
To be able to run such an monstrosity of an exhaust port without instant catastrophic failure there's a special two-piece piston with a retained piston ring(thanks Mark Atkinson). It has no holes in the skirt either, no short circuiting between the transfers and the exhaust.
I've designed the whole thing from scratch.
3D printed, cast(lost PLA), and "Nikasil" plated the cylinder myself in my garage. Designed the case and pipe for it. I've received lots of help from the community with things I haven't been able to do myself(lack of machinery and/or skill)
Especially machining, until recently I didn't even own a lathe.
Thank you guys, you're the best!
I've designed and built a landspeed bike for the engine, plan is to set a new class record at Bonneville.
Thanks for following the adventure, and fear not, I've already got plans for the next project - Symmetric transfers, four exhaust ports, two rotary valves(but not where you think they'll be), forced induction, no need for expansion chamber(!) ++
Many years of two stroke madness up ahead!
Easy is not worth anything!

Thank you for all the nice comments! As with all my other videos lately, this too was uploaded just as I went to work - can't reply until later. Really should delay posting until in the evening...
Thanks to you our two stroke Master for sharing your work. A little question: the piston = classique one or new model new idea with no needle cage, no axe who aims on connecting rod? I think this could really be a revolution... Starting with the dilation. You should patent this piston project to sell it to the Japanese.
Good luck to you for the future. Can't wait to see you blasting the 2 stroke 50cc speed record!!!

@John Morgan 👍 not a dumb idea!
@@2STROKESTUFFING fan du är så sjukt kul och intressant att titta på !!! fortsätt bygga :D
@@qylka 😁 takker!
Imagine finding out years later that the guy who made the most powerful 2 stroke ever was your kindergarten teacher
Hahahah that would be nice
Every time he mentions kindergarten I think this!!!!
That would be cool haha
He teaches the only kindergarten class with "foundry lab" in their curriculum.
Well start teaching this stuff in JK so by the time there in high school they will be 2 stroke wizards
As a chemist it is strange to watch someone dipping the ph paper into his solution. Dont do it like that, you will get the ph paper stuff into your solution and your ph reading isnt as accurate because you are wet soaking the paper. Use something like a glass rod to dip into your solution and put what ever stays on the rod onto the ph paper - much better way without contaminating your solution. Really liking the project though!
To me, (as a non-chemist) that sounds pretty smart...🤔 It seems like wouldn't be a huge deal but practicing good practices is always good practice...
I think this is called application error , like dipping a thermometer into a liquid will cause the liquid to cool slightly.
Thanks for the tip! I’m currently studying to go into a career in chemistry so that will definitely be of help going forward!
@@Doug791 or like how the act of detecting a photon changes its position?
@@ianbuilds7712 not exactly sure of that . I'm aware that in quantum physics , certain particles will only be there when you look for them. Weird shit.
I work in a kindergarden....
At night, I turn in to a two stroke Walter White.
Does anyone else think about Breaking Bad watching him wearing the mask in his garage?
Absolutely stunning, what you are doing. The amount of creativity is mindblasting. Simple methods combined with complex knowledge is a pure pleasure to watch. Keep on going!
Oh man, thanks for your videos!
I'm actualy making a cylinder for an old austrian Motorbike and this Video is making me think of doing the nikasil by my own.
But first I have to finish the aluminum casting process.
You showed me, that it is possible doing it at home, so 2 years ago I restarted my cylinder project from 15 years ago...learned CAD, did the construction work and now it's nearly time for casting.
Thank you so much!!
8 hrs a day in a kindergarten! You have my commiserations, you deserve a medal!!
Rita Payes stars fell ön Alabama last night
Girlfriend:’You’ve made a rotisserie, YUM!’
‘No’
First 40 seconds got me right in the feels. Father of 3 girls and soon to be 1 baby boy. Half built garage outside and a head for of ideas and dreams. Cheers. Keep up the progress, really enjoy your laid back style. 🍻
That is one hellish sound at the start, holy moly.
Nothing, but the sound they make can become a bit much...
Crotch goblin screams
I have gained a whole new level of respect for you and your mental toughness. Thank you for being a teacher lord knows I couldn't do it.
If I could afford to support you I would in a heartbeat. I have been fallowing this build from the start and its taught me a lot about 2 strokes along the way and also has completely changed my scope of the projects I can pull off in my workshop. Thank you for the hours of great heart felt content and inspiration. Cant wait to see this on some sort of land speed bike keep up the great work man!
Thanks! The thought that counts!
I donate 2 bucks a month. But I can afford it.
@@ossanyberg Thanks man, means a lot!
words cannot explain how excited and happy i am that this is coming together!!!!
I work 2 strokes a bit and had a similar idea. Never thought I'd work. I've watched your channel for 2 years. I anticipate great success.
the part where i see u get up in the night because your motivated to make this work means a lot to me .. its a passion its more then a hobby
Its easy to forget that he's doing all this for a record on a motorcycle. Its amazing to see that the riding is a small part.
I now fully understand the whisky after that intro😅
Rum. Lots of rum.
Impressive bit of work there, I hope it passes the cylinder leakage test after the honing etc., and that the collective postal services get their act together and get the other cylinder to where it needs to be. I am so happy that you seem to have some good momentum going and are staying focused and objective. Kia Kaha.
I’m always insanely impressed by the stuff you do at home, Awesome skills man
Australia/Austria... Same difference! LOL. I'll Put that on the list of things Americans don't have to deal with very often.
Love your work Alex!
Hahaha. Thats the only channel where i watch all the commercials. Love it❤️🤟 Greetings from Germany
Get a Add blocker. Works like a dream.
Love your work man this whole head from casting to playing has been amazing and I love it
Liked as soon as I read "A slow descent into madness". I totally get it. Well done on the plating, looks like it will be the ticket this time!
It looks like this cylinder is going to be quite sturdy. Excellent job.
this video feels elegant and relaxing...
I must say at first I was confused with the whole rotisserie engine dripping with paint thing at first, but then it made sense! Looking forward to seeing what's next
Apply one thin coat and reapply another within 10min....
Nahhhh i think imma build a rotisserie and dump this entire can one shot😂😂😂😂
Absolutely love these vids, 👌👌👌
Hey, it seems to work? Not so stupid if it works? :]
That paint is to prevent the cylinder wall plating from sticking where it should not.
its just a layer of cover, not a layer of point
pretty clever of him i must admit
Brilliant start!
stay strong mate. thanks for the share.
Very cool my friend. I am now all caught up on these videos. Looking forward to the next one.
I really enjoy your videos. Looking at your plating array i was smiling widely and thinking to myself. Rube Goldberg would be very proud of you. My projects are usually just as much disarray but much less well organized. Thank you, Sir.
Fantastic work.
Love it man, keep going.
You definitely deserve as many cocktails while working on your project as you’d like!!! 👍👍
That was really impressive! Great work! Nice to know I could replate my own cylinders at home if I had to 😜🙃
Best intro ever 🤣 need to buy some merch now
One of the Best opening so far!
Thanks 😁
Jeg elsker og se dine afsnit! Du er for vild !
Am I the only that thought while the cylinder was being sprayed on the rotisserie it was like watching a Tool or maybe Nine Inch Nails video? Awesome work btw.
love all the vid's keep up the momentum.
dude that intro was brilliant!! soon as i get some money its going towards saving you bro don't worry !!
Thanks man!
kindergaten: i worked as a teacher for ten years - enough is enough!! also: loving the neat use of skatewheels to provide bearings - that's my kind of thinking
That looks great, keep on 😁👍
wow that looks awesome mate! :D
Why did that music work so well. Loved it
That’s very impressive. These videos are funny and fascinating.
It’ll be interesting to see if there is measurable deformation with the torque plate on. You may need the diamond hone to achieve a nice round bore.
Sure will!
I've been counting the minutes waiting for this video today!
Nothing better to do?
@@LeoTonius Figure of speech
nice video, liked the jazz alot. helps to relax ;)
It is very relaxing to me to see you pour yourself a nip...to contemplate...then take action on a well thought out plan between your ears ...then to share it with us....and to wake us up with the buzz saw ready to hit 15,000 rpm and blow into 1000 pieces
Had to make a donation!!
Thanks, means a lot!
Anxiety is soluble in alcohol. Thanks for another great video.
I am fortunate to have lots of Swagelok fittings gauges valves etc...to have built my own leak down tester...
Also great score you had with those new machine tool goodies...
Good job on the platting tweak! However, I still have concerns about the pitting in the original casting.
Sooooo cool. I would love to see a video on your honing tool and the rotating tools you made. Is there a video? #how2wrench fan here!
Everything makes since now... the building of the log cabin by yourself, the hours in the "shed" by yourself and the drinking by yourself...KINDERGARDEN.
Spot on!
Find myself not watching your videos in logical order, reflections of my life at this moment currently. That said, I've drawn a interesting similarity reflected in yours. The audio clip of the kindergarten kids was the key, I would bet that the average overall resonance frequency of a 2 stroke engine would be pretty close if not darn near equal to that of the kindergarten audio clip. Many many thanx for your time & content, it's extremely enjoyable no matter the sequence it's watched in. Best wishes from Andy G in NZ.
I now understand the deathwish! Keep on keepin' on!
Just got my two stroke stuffing shirt!👍
This is a cool process that's over my pea brain... Classic question of "who the hell came up with this" method.
Probably some scientists payed with ur tax money.
@@handendaer I suppose you think they should have figured it out for free and just ask for donations? Lmao
It is called stress plate
Electroless plating was discovered by accident by two engineers working on making cannons last longer. They forgot to turn the heater off at the end of the day and left it on overnight. The next morning they discovered the plating without using rectifiers. The hard part is recognizing that a mistake can be a whole new technology. Most people would clean up the mess and forget about it.
Instead of a thin mil coating that might not offer full or robust coverage, I'll probably just buy the cylinders and use additive nano powders of BN, Graphene, and TiC (2D ceramic sheet MAXene materials). I'm thinking that any silicate dust, amorphous carbon deposits, or metal burrs that make their way into your cylinder region will be pretty hard on the soft supporting nickel matrix.
Instead of Nikasil, you could also look into ion beam deposition (form of PVD) of a bonding layer like AlTiN, with a thicker chemical vapor deposition layer of diamond-like carbon over top (all parts can be coated this way). I may make the cylinders out of Hastelloy C (low thermal conductivity + superalloy resistance) or a titanium alloy if I take this approach over Al2O3/TiCN/SiC/SiN/ZrN/CrN cylinders (wide variety of ceramics suitable).
Omg i love these
I've read about cylinder bores being finished with a fine grit brush to break the peaks off the honing in order to improve ring life.
👍 Makes sense, thousands of sharp carbide points can't be the best for ring life.
good job bro
Best, LOL entrance I have ever seen!
I have that same leak down tester. I'll be extremely impressed if you get one test out of it before one of the gauges dies. That's what happened to mine, anyway.
As I sat here watching the video the best part was when the mad scientist was doing the plating on the cylinder I was waiting for the police to break down the door thinking it was a meth lab
Real good work, looks good. Regarding the 3 point meassurement it is not recommended, use a good boregauge like the one that broke.
The normal honingstones will just wear out quickly, wont harm anything.
Looking forward to watching it running again.
👍 Thanks! I'll see how I like the 3 point but am getting a new one of same type I broke.
Cool video, I was wondering what peelable spray you use to protect part of your cathode?
IF that leak down tester is one of the cheaper ones on ebay and the likes, its junk, well, the regulator part is junk, it has so much hysteresis you cannot get a reliable and consistent reading to compare between cylinders. Im a mechnic for a living and bought one to replace a snap-on one I drove over .. ended up buying another snap on one. if you replace the regulator with a quality part, it should work as intended. Also a DIY vacuum leak tester is very easy to make with a variable power supply, gauge, and an automotive 12v vacuum pump(for brake servos) .. I use the latter to test valve and piston sealing with the head off. very handy for troubleshooting a dismantled engine. just found your channel today :)
👍 It's from a local shop, but likely similar quality to eBay ones. I'll see how it behaves.
👍 on the leak down tester.
The music is giving me flashbacks to a very, very difficult video game...
Brilliant news
Fantastic!!! A few more steps and it is start up time again.
What setup will you run?
Full crankcase volume or not?
Secondary intake valve fitted or not?
Injection working or not?
I love the adventure you are on. I purchased a RGV250 VJ22 in Osaka, but covid means I cant get to it at present. When I can get there it is getting a Nitrous Oxide setup with dual map computer. Have you played with Nitrous Oxide and two strokes??
👍 Full case volume without the valve first, then add in variables from there. Never played with nitrous, but I will!
good call w those 3d printed inserts
5:15 "when there is too much, that's not enough" 😂😂
Fiy there is a commercially based sealer used to be called 31x red by M&T chemicals paints on just peels of. Specifically designed for electroplating.
👍Thanks for the tip!
great video as always. what is the particle size of the silicon carbide powder that you used?
Love it
5 to 10 microns are 0.005mm to 0.01mm.
You can make diamond honing stones by taking pieces of aluminium the same size as the stones and charge the surface towards the cylinder walls with diamond, search for charging a lap.
I would like to try that too.. Is there any "how-to" with the mixture from the "Nicasil"? Where to buy the chemicals?
Love your work! 💪
👍 Nickel plating chemicals from Gateros Plating, SiC powder from ebay. Just like a normal Nickel plate but with the powder mixed in(needs a pump)
awesome vids
Someone with this much knowledge about engines should not be working in a kindergarten
Give him a break. Iook at his work back in the summer.
@@zackeudy6236 it wasn't meant to be negitave I just meant he seems to be very skilled with engines and not too fond of the kindergarten and which video mentions his work in the summer, I'm still quite new to the channel
It'll be fine Patch King. Stay well.
You could say...
"Teaching the kids early" !!
I got it, no worries! I actually enjoy working in kindergarten, someone has to teach this kids how to not be a sheep! It can be extremely tiring at times though.
I love the intro 😂
I think normal honing stones will work. Because if you sand a cylinder you can remove the plating
WAY over my head but really amazing.
I don't remember if you said it in the last one but... you couldn't use wax to mask it? And btw when painting something, even for masking, give it a coat and let it sit till it gets tacky (sticky) to the touch then hit it with another coat and repeat until you get to the thickness you want. Just continuing to spray more paint on it while it's wet isn't going to do anything but make it run as the weight of the paint overcomes the grip on the part. Oh and btw I messed up on my comment about heating the nitric acid it doesn't make dinitrogen (I was thinking of dinitrogen tetroxide) it makes nitrogen dioxide when you warm it up too much and it makes that red/brown gas. It can also make nitrogen trioxide too. Either you need to figure out a way to fill those holes or a recast needs to happen. It might be down to the alloy you used to cast or the plaster casting, I don't know but those holes definitely need to go. I wonder if you could do plaster for the passageways and do a sand cast for the exterior or if that'd be too much work. I'd be tempted to fill it with copper like they do with chrome and then do the nickel over the copper once the holes are filled.
What would the consequences be if you increased the ampage in this plating process? Only reason I ask is..... If the resistance of your cylinder is unknown, how do you calculate ampage?
Thanks you for all your experimental work and your positive attitude towards failing. We all stand on shoulders of giants and you sir are a giant.
Thank you again.
Thank you for showing all this work. If you can answer me, after the last step, 1.5A for 5 hours, did you measure the coating thickness?
Awesome work,i really do hope you get your cylinder but your probably better casting another one considering its taking 3 + weeks on average at the moment to receive mail from nsw and im in Melbourne.
Thanks! Yeah, talked to them on the phone today. No apology or anything, just said I had to wait for it to get sent back...
This guy is like some kind of genius mad scientist lol very entertaining !!
"Pennsylvania usa "
Ya i got this place called Millennium Technologies i send my stuff lol. I applaud you for taking this on yourself but the materials an esp the knowledge lol.. I guess its just easier for me to out source it. Loved watching tho, so cool
Working in a kindergarten explains the rum also try Ms Figgins pineapple rum by Plantation. It is INCREDIBLE a recreation of an 1800's recipe where its actually distilled pineapple and macerated pineapple skins vs just an infusion. It is INCREDIBLE.
Also awesome that you have the testing tools now looking forward to seeing it in use.
👍 Thanks for the tip, need to try that one!
@@2STROKESTUFFING it's amazing. I got really lucky and scored a bottle for £20 should have been nearer 32.
Cool stuff! So is the nickel plating acting like a matrix to hold the hard SiC on the surface of the aluminium as a kind of composite?
👍 Exactly
holy crap Im not the only one who works at a kindergarten and spends my money on two strokes!
I love 2 strokes , such a simple motor, not a whole lot of moving parts, no cam no valves no push rods, no springs no timing chain pretty much just a crank, connecting rod and a piston are the only moving parts plus they are really easy to make lots of HP
If it turns up at my place I’ll send it on over.
some serious porosity in that casting
How about this: You build up the zinc for filling the holes, then hone it to shine, then start the process from the beginning. If the zinc layer is sufficient, You can even try to skip the zinc bath part. Just because Zinc is malluable, but Nikasil is not.
The final plating sufrace is not designed to be honed at all.
i plated for 23 years ,,pitting is too big ,,that cylinder would be sent back as scrap..no proper cleaning, soak 115 , electric cleaner,acid ,,rinses ,,anode installed after plating has started,sleeve the thing ,,PEACE
@@MeanOldBastardBikerBob Those pits can be used as anchor points for the galvanized zinc/Nikasil sleeve. No press sleeve needed. Nickel can easily penetrate several milliteres inside the zinc layer, so just rinse the bore, coat it heavily with zinc, hone it to proper diameter and shine, and harden the zinc with nickel.
in my plating experience i say the pitting is to large and would require too much material and cause peeling PEACE
I worked for a company years ago(1980s) that chrome plated their 2-stroke engines. (Plated, not Nikasil). A small percentage of porosity was acceptable and desirable to allow for some retention of oil on the cylinder walls. I agree that the pores observed in this cylinder appear to be too large though.
I'd I like to ask a question .
i've been a subscriber for over two years.
i've watched every video on your two stroke ..
my Question is ..
How How does it feel to come this far building this ?
make a video i'm curious . There must vbe some sense of something.
Nice content good videos , keep up the good work !
BTW Sorry sorry about the spelling my keyboard shorting out
Thanks! Feels great, but this is only the beginning!
