Starting the Worlds Most Powerful Two Stroke again - 100% Wide Single Port, FU*K U!

Welcome back to my garage. The moment we've all been waiting for is here. Later in this video I'm starting this engine. After more than four weeks the pistons finally arrived. USPS tracking still says they're stuck in the US, so strange. These pistons are slightly different to the old version. More threads to make it more stable. Extra ring here, which will be pushed up against the ledge in the piston top to keep the gap, the ring consistent. Give the right clearance for the ring. Enough talking, let's get the piston assembled, installed in the engine and let's get it started. So And we lost power, and it's back. I'll spin it over without the ignition and the fuel hooked up for a little while just to see that nothing goes wrong, and then we'll start it. If the ring catches or anything else goes wrong in the bore, now we're wrecking a prototype custom 3D printed metal cylinder worth maybe $2,000. The ring broke. The cylinder is fine, thankfully. From how it's curled over, it looks like it caught the exhaust port floor. We're giving it another go with better chamfered ports. If that doesn't work, I might just put this 100% off bore exhaust port idea on hold and make a port with bridges. Here's my old broken spindle motor controller, and here's a new one, thanks to Keith Phillips. Thank you, you really saved me here. So now this seems to be plug and play, so I'll get this into the mill and adjust it properly, and I'll be back when the mill is working again. A huge thanks to Jim Locke at Sprint. I sent him a mail for the fast and helpful replies, and he sent me the schematics and the specs for this transformer, and what the hell, I ripped one of the legs off here. Well, it doesn't matter because it is shot anyway. I can't find a suitable replacement locally without hacking something together, but Jim kindly offered to send me a new replacement. Awesome. Chamfered the cylinder better, new ring. Let's see. Exactly the same thing happened with that ring. Here's the previous subject. So obviously there's a weak point here. There's not enough material around that pin, and it breaks. The reason for this is obviously the force from that ring being pushed in by the exhaust port, so I'm saying **** this 100% of bore single port. Just **** it. I'm not going to abandon the idea completely, but I'm going to separate the 100% of bore experimentation out of this cylinder, bore it out, sleeve it, and put a bridge in there. A bridge or two. I'll start with one, maybe make two sleeves to compare them. In blowdown specific time area, this actually doesn't mean more than support for one less horsepower. I've got plans for testing a lot of exhaust port related stuff. We'll put that 100% of bore into that stuff and get this engine running. It's been three years now. Yeah. We're not abandoning the pistons though. We're running them with normal rings. There's a few more advantages of these pistons apart from the captive ring. First of all, they're just as light as a comparable piston. Completely symmetrical as far as heat is concerned. The expansion is more symmetrical in these pistons. Should be. And there's no holes here, so there won't be any short circuiting between the exhaust port and the transfers when that wrist pin passes by. I'm feeling kind of freed from the 100% of bore cage now. You can't let things become a cage. At least I can't. I hate cages. Let me grab my computer and I'll show you the sleeve I've designed. And also I'll give you a sneak peek on what I'm working on for after this. The aftermath of this. Here's the cylinder and it's now been bored out to accept a five millimeter sleeve. There's also a step here for kind of a ledge. So there we have it. And as you can see, there's now a bridge in the middle there. Not ideal with this shorter bridge, but that's all you can do with a sleeve. At least this will make the cylinder usable for now until we find a way to make that port work. So that's... I have an idea about a company in Norway which have the machinery and the capabilities to do this for me. So I'm going to send them a mail and see what they say, how much they want for it. I really need a five axis mill. At least a four axis mill that would make this doable, I think. Or do it by hand. It's actually possible to turn this down. I want this to be an aluminum sleeve with plating. So Blixen Racing, I'll be talking to you too. That sneak peek, that sneak peek. I'll give you a hint. There's supposed to be a supercharger involved here. And these are rotary valves. This is just a sketch, by the way. It's not a final design and it's just to see how things will work together. It's made to fit my existing head. And the same crank. Still 50cc. Okay, thanks for watching. Can't wait to play with an actual running engine again. It's been a while now. Clyde Labonte, that's probably pronounced incorrectly. Thank you. Thank you for... He sent me the 1987 rulebook from Bonneville. And a CD with pictures of cars at Bonneville that year. I need to find a CD player. Kind of funny how CD players are not around anymore. But anyway, thank you. Thank you. It's a really interesting and really cool piece to own. So thank you. And again, thank you Mark for making the pistons. Thank you Blixen Racing for the plating. Thank you Proto Labs for printing the cylinder. Just thank you everybody. Thank you. A special thanks to everybody supporting me on Patreon. Thank you for watching. Thank you for supporting me. Just thank you. See you next time. If you saw the video about this thing, I'll have you guessed what it's going into yet.
