Long time sub, I really wanted to take the time to point out how good your cinematography has come! It is an absolute pleasure to watch you work on anything. Cheers from boston.
Thanks man!
Nice precise machining with wood and hand tools. I would fly on any aircraft you worked on.
+upside downdog Thanks! I'm not sure I would go anywhere near that aircraft myself tho...
2STROKE STUFFING
Don't sell yourself short. You do nice work. I haven't seen you use rocks and sticks yet, though.
+upside downdog 😂 Thanks!
Maybe a Safety Tip. Use C-Clamps,or a Vise, instead of Your Hand too Secure Your Product, being Machined !
Great example of making do with limited resources & a creative mind .... just like the infamous Burt Munro depicted in the movie: "The World's Fastest Indian" (2005), one of my favorite movies.
Top quality fabrication as always👍🏻Just seeing you work gives me inspiration on how to do jobs differently,thanks again looking forward to seeing it rebuilt now👍🏻👏😎
+ninjanelly350 Thanks man!
a video about rotary valve timing would be nice! greetings from austria!
+AU[:T:]woStrokerZ I'll make one in the future!
6:35 double angle cut on rotary valve!!! ... I do the same on my vintage kart racing engines (135cc B-Bomb & BM130).
I grew up in the 70s I had a 185 Suzuki piston port engine my friend had a 175 Yamaha reed valve engine neighbor had a 175 kaw rotary valve all stock these bikes were the rotary design had much more power than the other design
Have you thought about having the inlet angled more so the flow is going towards the cylinder more.
On the late rotary valve kart engines they moved the drive sprocket to the ignition side ( the opposite side to where it normally is) so they could fire the charge flow up in to the cylinder more. Have a look at the IAME TT39 (later model), Rotax DSE-L and there was a Comer engine to.
+Devinder Athwal Thanks! I have, and others have mentioned it too. First I thought the difference would be miniscule, but as you pointed out, if they went to the trouble of relocating the drive sprocket it can't be. Definitely on my list of things to try!
If you use a 1/4" shank 14 degree 'tree' burr it saves you some time and gives a better angle for transituion
always funny seeing you machine parts with the moost cheapest stuff. I was wondering if I think to much when machining simple stuff..... any ways, keep up the good work!!
+Klavers FMT Thanks! It's surprising what can be done without the proper tools!
I hope youre happy with the quality of the intake rubber,happy new year :)
+Joker1911able9 I am, thanks again! Happy new year!
Made my day . I have to get a router and get cutting
+45zuko Awesome, thanks!
Loving the the videos man. Thanks.
+Sicdoc 58 Thanks!
Nice done!
+yummii cola Thanks!
So awesome brother! Great video!!!!!!!
+Dillon Statler Thanks!
Very interesting video. Been following allong for a while and see that you are really interested in what you are doing, not to bad at it either :D
Thanks!
Iam also workingon a suzuki a80 and i am trying to put a stage 6 cylinder 96cc on it with malossi water pump. Love your videos very helpfull
@t2stroke stuffing the Doppler crankshaft can break fast. I had it also with a MK pro race 70 (piaggio) the rightside (flyweel) where you add the locknud (dont know how say it in english)
The best preformance i had was with a Kiesler. Still awesome video bro!!!
+Andre Verspoor Thanks, and thanks for the heads-up! I should really re-machine the case for something else, Spx crank selection is limited.
Artek cranks are typically better and stronger than Doppler ones, Doppler quality has been constantly declining lately.
Thanks! I'll try one next time I need to replace it.
Great work . Sounded like you were getting a little bit of rubbing on the valve
+ben hall yep, didn't clean/sand the cover, need to do that before assembly.
You're amazing !
Thanks!
well fuck yea!
Godt jobbet!
+Håvard .EF Takker!
I see you pulling down hard on your drill and miter . Let the machine do the work . Put a bit of soap on saw blades and drill bits but you must know this ! I can't get my 50 cc past 10 hp .
P.S that's a sweet little motor you built !!!
Thanks! And thanks for the tip!
Wow cool
+Saline Woodworks Thanks!
Aren't you worried about the gasket sealing by the top of the intake port? It looked to me like i could see some light between the top of the case and the gasket... unless the cover for the rotary calve seals against the cylinder when it's bolted to the case?
+Stephen Lichtenberger Thanks for the heads-up on that, I actually hadn't noticed. Might need to adjust the gasket a bit or cut a new one.
Same suzuki TRS118 intake valve
I would love to hear more of what you are doing, for instance, why did you go with that size on the Intake Port? why not bigger? why not smaller? did you do some math to find out what size you would need to use? Why did you put it there and nowhere else? Just do a little mor explaining. Most of there i already know, but it would be quite nice for other People witch just have basic onderstanding of 2 Strokes. understanding of
Thanks for the input, I'll throw in some info in an upcoming video!
Working safety!
Check drilling table 2:40!
I have safety job sertificate and safety job in Finland is wery inportant, and Im comming back to Finland in April :)
+Rudolfs Jozuus Safety first!
Great job man I"m a huge fan of yours. Tell me how do you install a rotary valve. I have parilla engine where walve can be installed in five different positions. So how to know when it is on in a correct way? Thanks.

exelente trabajo.pero Kawasaki GTO 110 tiene esa válvula...
When cutting carbon-fiber, keep wet the piece so the dust get trapped in the watter instead of going to your lugs, a proper mask is recomended, that dust is dangerouse for the lugs.
Hello, always Great video! But watching it seems you assembled The disk thinking on the wrong rotation sense of the engine, actually right, you reverse it. Difficult to say from outside but it seems. It is a easy mistero, i usuale write an Arrow help helping to put on right sense. A question, watch timing you use, i mean before/after tdc? I will subscribe soon...
+Vns workshop Thanks! It's on the right way, but as you say easy to get confused even with simple stuff. Running 145/88 intake timing.
I want to ask the master of my suzuki TRS motorbike, the combustion system still uses a rotary valve, if there is a jet of gasoline coming out of the gas from the carburetor, what is the problem master? Greetings from indonesia...😊
Nice work!! To my eye shouldn't everything be done about now if I have thought of everything
+HeppaJuuso Thanks! Yep, just some cutting and balancing on the new crank left!
2STROKE STUFFING are you planning to experiment with the length of the intake manifold to find the sweet spot between high and low end power band? Thanks, I really like your ingenious machining methods.. no fear! Keep it up.
+Jon Rothenbusch Thanks! I've been playing with it in engmod simulations, it should really be shorter but that's hard to achieve.
Sir.whats the purpose of line behind the rotary valve?
amazing
Great work ! I was wondering if the clearance between the carbon disk and the walls was an influential parameter for the engine tuning ? Cheers Man !
+seinthomas won't matter much if kept within reason. Too tight and it will generate alot of friction, too loose and starting might be a problem(so they say at least, mine started fine without no valve in there at all...)
Funny how the router is saying "nearly, nearly zero, nearly nearly zero..." Don't ya hear it?
+Aku Korhonen 😂
Nice video, just getting my head around rotary valve engines. What is the material you use for the the valve?
please excuse my cheek, you look like a man who is worth asking. i am thinking of sticking a cheap chinese cdi on my honda crm250 mk11 to maybe get it going.im a bit foggy about the timing curve. i have already bastardised the flywheel by grinding off some of the bumps. have you any views on this? cheers
can you make a video about intake port timing for a rotary valve?
+Ewout Wielenga I can in the future!
That would be awesome! thanks alot
Good day...
What is the best for racing porpuse
Rotay valve or reed valve
Hai mate.... I like your video, How to get correct degree for suzuki gp125 and cutting edge for rotary disc valve..... Thanks
+Sopi Alpiano You'll thank me for this one, read the whole thing! www.kiwibiker.co.nz/forums/showthread.php/86554-ESE-s-works-engine-tuner
Thanks mate, the forum very helpful... 👍👍👍 For you
What rotary valve material should I use?
I have a 125cc bike, im modifying it so it can go way faster than before
But I always fear the rotary disc will break at high rpm's
What material should I use for the disc?
Didn't you want to keep the screw at the 11 o clock position out? You cut a hole for it in the cork.
If you now leave it out, it will leak.
+Tilman Baumann true, forgot about it whencI cut the gasket... Have to plug the hole.
Is a rotaryintake better then a membranintake?
Becouse i think a membranintake is easier to build
+mace Better for peak power, at least on small capacity engines.
Fascinating content as ever, love your accent, a bit like the Swedish Chef* for 2-strokes "insørt søme tøngsten sløgs" :)
*From the Muppet Show, look him up - he is also a trained professional
Thanks! I'll check it out!
Sir. How you made the rotary plate or were did you got it from it would be very usefull for me thanks.
Looks good man! How heavy is this though? And how much force will it take to rotate this when lubricated by the fuel?
+The Esseboy Thanks! Haven't weighed it, but it's lighter than the smaller one made of steel I ran before. Not much friction at all during operation, as long as there's enough gap between case/disc/cover.
2STROKE STUFFING ok, looks nice and sturdy anyhow :) good for excluding possible causes of problems :D Really like your content, so chill and informative! Keep it up, cheers from Finland :)
+The Esseboy Thanks!
Great video, what's the lining on the ceiling of your workshop? Is it some kind of soundproofing? Thanks.
+Dave Spooney Thanks! It's actually just the insulation covered in plastic. Not finished yet, should prioritize it but you know, more fun to work on stuff in the garage than work on it...
+DeviouS true.
Yup, know that feeling. DIY house repairs or upgrades are a bit of a chore in comparison.
what is the point behind a rotary intake?
Asymmetrical port timing BTDC/ATDC and no obstructions when it's open.
@@2STROKESTUFFING ah interesting! Thanks 😁
Its said reed valves are better option
What does your ratory valves have to offer that reeds dont
Higher rpm ?
+Bass It The advantage with rotary valve is nothing in the way of flow and no delay like with reeds.
My friend..good video. I'm buy the Suzuki gp125 whit rotary valve.
great your video
Is it more admission in the camera?
Thanks! Didn't quite understand the part about the camera?
good night friend. What I am asking is if the cut that you made in the rotary valve helps to a better admission in the cylinder? And and how do you measure to get the angle of cut and not leave the motorcycle choked?
Yep, it's cut to work good at high rpm, long duration, open 145° BTDC, close 88° ATDC
I run simulations in engmod2t to find good port timing.
thanks mate, it's really usefull... I have to do it... Good videos.
Hey Brother I looked at those spark things and are they $125 wow that's a lot there ain't no cheap ones 10 20 30 Maybe let me know brother
+Critical Mass Critical Mass No cheaper programmable one's that I know of, sorry.
De qué moto es este disco y cuánto Cc
Exelente..
Tengo una yamaha vrr 150 cc 2t. Que me recomendas para prepararla. . Saludos desde argentina
+gino benicio Thanks! Sorry I can't understand the rest tho...
He said he has a Yamaha una vvr 150cc 2t and is asking you have any recommendations for it. and basically greetings from Argentina.
+Kole DeWoody Thanks!
What size end mill are you using in the router?
+Kole DeWoody 8mm, it comes with collets for 6 and 8mm.
I wonder if the US sold routers have metric collects. I believe its 15/64 in inches. Will have to look into this since my mill is an hour away.
Do you need any more small 6mm colleted end mills? i cant use them in my big mill really. i think i have 1.5mm - 6mm spare.
+Kole DeWoody Sure, that would be great! BTW, Send me your address to 2strokestuffing@gmail.com and I'll send you a couple of the Shields!
is you phone sony xperia xz? because it seems the same as my
+Lauri yep.
What is the point of Rotary valis
+Thelgeokiller 15 To control intake timing, just like with reeds or piston port.
What are better rorey or reed
+Thelgeokiller 15 Rotary is best for peak power, especially in small engines. Reeds are better for most everything else.
So should i get a reed vaile for my 66cc engine
I want
Pressure leak.
An idea for the future once you've got this motor running ok, is a slash cut to the opening edge of the disc. Nicely represented by this superkart engine: www.pvpkart.com/252%20RH%20with%20disk%20valve%202017.jpg. With this the port opens first at the bottom.
Have you managed to model your engine in Engmod2t to your satisfaction?
+cara vaggio Yep, it's modeled in engmod. Matched reality pretty good before porting. The problem with my upside-down setup is the opening edge of the intake port is almost horizontal, no matter what shape I cut the disc it will always open top first. The remedy would be to flip it around, might do that if(when)I build a new frame for it.
🦑
if you leave the.admission value open while the note goes up to pms it would not perform better because it filled.more the character?
I'm brasilian
I playing for videos
Enjoy 😊
My Inglish is not very god
+Campagnolo MotosTM You're talking about the valves orientation on the crank right? Don't worry, i just tightened it down in a random spot to see how it rotated, will time it properly when assembling the engine.
dUDE! LOVE WHAT YA DOING!! KEEP IT UP! BUT USE A LITTLE CUTTING FLUIDE WHEN WORKING THAT DRILL PRESS? THINK YOU WERE GOING TO BRAKE THAT DRILL BIT!! BUT ALL IN ALL, LOVE WHAT YS DOING !! DO YOU KNOW THERE A WHOLE INDUSTRY THAT USES TWO-STROKE MOTORS BUT THEY DONT DO ANY OF THE TIMING OR IMPROVEMENTS THAT YOU DO? THEY DONT EVEN DO BACIS CHECK FOR LIKE PORT TIMING MOST OF THEM WORKING ON THESE ENGINES DONT EVEN KNOW WHAT PORT TIMING IS?? AND THIS BUSINESS IS WORTH LIKE 150 MILLION IN THE STATES ALONE! WHAT YOU DO WITH TWO STROKE AND THE ENGINE DESIGN I HAVE WOULD CRUSH ALL OTHER ENGINES IN THIS FIELD. JUST THINK DONE RIGHT, TAKE 50 PERCENT MARKET SHARE OF 150 MILLION? LET ME KNOW.
You shouldn't fast forward so much on the editing. If I'm going to watch a 10 minute video of this I'll watch a 1 hour video of this.
+Jason Henderson 👍 Noted, I'll slow down a bit.
Im 500 likers. Haha
+mohd aidil Sweet! Thanks!
.
Holy shi.. what a bad build...
Weld in the tungsten slugs? Weld over them? Or are you going to stake it into place by peen-ing the metal around it? Tungsten doesn't like welding, it could be brazed I guess.
+Toaster Chicken I welded them in with flux core(!) last time and believe it or not it held up! Probably going that route this time too. The slugs are some kind of alloy(actually derby car weights), and fused fine with steel.
Hey Brother I looked at those spark things and are they $125 wow that's a lot there ain't no cheap ones 10 20 30 Maybe let me know brother
