The Most Powerful Two Stroke Assembly Part 1.5 

Spot on, develop your ideas and others can create the basic components

Super cool!!!!!!!!

You go girl ! Did not think 2 Strokes turned Women on .

@@peterbaranyai6057 I grew up around all kinds of motors and engines, I just love POWER! I find that 2 stroke engines are in many ways superior, and some of their alleged drawbacks are most likely due to engineering flaws, not flaws in the principle of being a 2 stroke cycle engine in and of its self. Detroit diesels, back when they were 2 stroke, were much more powerful than the 4 stroke engines, but got booted because of 'emissions' issues, which, if properly corrected [which the MTD corporation went on to do] would not be any problem. I know that the same is true for 2 stroke gasoline engines as well. They are just not engineered properly for 'acceptable' emissions and efficiency for the most part. I can not say wholesale of course, because, like this one here being made so marvelously, the final results are far from known still.

Chris Valin electric just doesn’t have the same charm or visceral appeal to me - no matter how allegedly efficient they are. Once you see what Lithium poisoning does to people, you realize that they’re not the “white technology” they’re touted to be.

@Chris Valin I see you are a dupe of the globalists and religiously buy into the hoax of clean energy. You are trying to sell these bullshit propaganda lies of the globalist left to one far more aware and knowledgeable than you shall ever become. Walk on home boy.

@@DeliciousDeBlair oof, just when I think I agree with someone, they turn out to be crazy. lol!

how is the 4 cyl doing?

I decided to win the lottery, but the Universe is still minding its fucking own business.

I watched your casting wow good stuff, I've thought about 3d printing something and casting it. I'm pretty sure there is plaster that you can pull and vacuum on. Anyway great vids!

He did the nikasil coating himself, it's not the the same compound, but it's similar and has a lower friction coefficient.

Who is sv seeker?

@@guxyguy7909 An asshole building a boat on YT.

Oui ce montage est très étonnant, le piston est spécial..

Or just bore the bottom a lil more, It won’t matter if you bore just the bottom cuz the piston rings won’t go pass the exhaust port. When you open an old top end the bottom of the cylinder looks brand new

You can not bore a plated cylinder to achieve a tight tolerance and the necessary cross pattern honing produces. Without honing the oil has no place to stay inbetween the piston and the bore so it will rub mechnical and fail due to overheating caused by friction. All thats needed is a proper hone, just give that thing to a dedicated machine shop an tell the piston diameter, they will hone the bore to the right or demanded size.

@@daniel_6741 I can bore any metallic surface you can throw at me. I might need diamond to do so, but I can doi it all the same. Technically what would be best is what is called a 'bore-grind' where the cylinder is set up on a bore grinder/honer machine and carefully sized then surfaced. Since they make some low melting point aluminum solder, one could even go so far as to clean cut the entire bore, carefully aluminum solder it back INSIDE minimum dimension, THEN re-bore it to pre-plating bore diameter [with proper surface resolution] and THEN go back and re-plate it. A helluva lotta work? Yeah. Wiorth it? That's subjective to the individual. Better plan? Laser print the whole cylinder from titanium and then bore, hone and plate. As far as the 'required surface roughness for holding oil' that is a quality that a highly skilled and informed machinist can pre-program into the boring/finishing process just as accurately as an old world high precision manually operated engine hone, and far more precisely than a human hand. Ideally a steel, cast iron, or ceramic type cylinder sleeve could be incorporated into the engine when it is being cast for a far more rigid, reliable and long lasting surface for the piston and its rings to travel within, even if you skipped casting and actually laser printed the engine head in place around it.

@@DeliciousDeBlair maybe could bore it out more and get someone to make a sleeve for it

Wait a couple years. They're getting cheaper

I'm sure the Russians also know a variant of the old English saying "If you want something done right, do it yourself." I suggest you get cracking.

Liners/sleeves are a bit 18th century. There's a reason competition machines use Nikasil or similar coatings.

I'm not sure about today's 2 stroke racing tech, I've been out of it for too long. But back in '98 a good friend of mine ran a high performance Gilardoni cylinder on his scooter, and it definitely had a replaceable sleeve. A Nikasil coated sleeve.

@@remcovanvliet3018 4-stokes use Nikasil coated aluminium blocks too! And it certainly is not new; introduced by Mahle in 1967; used by Porsche, Jaguar, Honda, Suzuki, Kawasaki, Yamaha, KTM, etc

@@DepakoteMeister any sleeve or coating is as good they all have good and bad but iron sleeve are way easy to make at home not like some nikasil coating and all the dangerous chemical it need And nikasil is only use in small engine

@@legros731 What rubbish, some Porsche 911s use Nikasil, some Ford Mustangs use a different coating. This guy is designing and building the world's most powerful 50cc 2-stoke, for that he needs cutting edge technology, not what's 'easy'!

Diminishing returns, larger than 100% bore width doesn't gain much power, and would also reduce the structural strength of the cylinder.
