Cone Engineering

That's a 16 inch cone on there. That's a little 12 inch there. Zeke, we're here with Craig at Cone's Inc. Tell them what we're trying to do with Lucky. Do the time, you can go 100 miles an hour. Wow. See you. So you want to run a Bonadil? So you want to run flat out? Yeah. Throt a wide open. So you want to build your exhaust pipe a little shorter. If you don't need the torque, for the longer your exhaust, the more torque you'll have, the shorter your exhaust, the less torque, because the more arms you'll get. You're carrying these short on your lap. So you want to run a little shorter. You want your head pipes to come out. You're no longer than 12 inches, probably even a little less. And when you get to your collector, your secondary pipe should be no longer than 3 inches, 4 inches. And then you just put a pipe on there. And you don't want to go too big. People make the problem of going too big. So when you build exhaust, you have pulse velocity, or you have pulse vol So velocity builds a good tune motor that has torque and horsepower. You can ride around corners. You can do all that other stuff. And this pulse vol Guys that just want all the horsepower they can get, they just will have nothing on the bottom end. So if you shift gears, it will take you a long time to go through the revs with the pulse vol So we always But in your case, if you want to just go straight as fast as you can, just know that it will take you a long time to go through the RPMs. Once you get up there, you'll be great, right? And so you want to focus on pulse vol So you want a little bit bigger diameter. But don't ever go more than an eighth of an inch increments as you test. So when I build a pipe, I built pipes for race bikes when I set up for customers. I may go through 15 to get it right. And I've been doing this for a long time. Actually, it'll be younger than you actually, with my dad. But the biggest problem is that they make two big adjuncts. And when you change exhaust, you make one change at a time. You never make two changes. Never. Never do it. Just make one change. If you want to change a little bit of length, just change the length. Don't change the diameter and the length. You want to test that. You want to learn. You want to learn from the failure. What you basically want to set yourself up for is to fail about five times. Once you fail the five times, you're going to gain ten times the amount of information. But you can't learn from it if you make two changes. Because you don't know which one affected the result. Pulse vol It makes for a better tuned bike. So if you lose the tune, you have a hard time getting your car set up. So why? You've gone too big. So you either out capacity the carburetor and you just can't find the right jets to get it going right. Or you need to come down on your exhaust and diameter a little bit and bring back that tune so that you can start to tune the bike so it runs properly. So But on our bike we need pulse vol Correct. Because all you want is wide open and the maxim The only problem that you're going to have is that it's going to take you a long time to get through the RPM range. Yeah, hardly any problem. Right. So we call that a pipey bike. A bike that's real pipey is a pipe that has a very narrow power band. It'sort of It just takes off. And that little take off point, we call that a pipey pipe. Okay. And we need to be at 10,000 RPM. Exactly. So if you'really short, you can go with vol You want to stretch that torque curve out and make it a little bit more rideable and get through the RPM's better. So in Bonneville, one of the biggest problems is getting up to speed. Yeah, because it'solid. It's your whole setup. You have such a tall gear that a lot of guys, He's on Bob's big week out there. Yeah, he wants to run the Bob. I will, if you get, you got my card, you call us back up. I'll call Dennis and have him talk. He's done a land, well he's held a land speed record. He knows what he's talking about. But one of the big issues that they always have when they're trying to go really fast is just getting up into that gear. Because you've made the pipe so pipey, it'so narrow in horsepower band, you can't get there. So that's where you just play. Vol So is there a way to have vol That's the art part of exhaust. That's why there'so many people that sell exhaust. I'm one of a hundred people. There'science. So the science is your stroke, your bore capacity, right? Yeah, exactly. You need to learn the value of speed, right? So that when the exhaust port opens up, how fast it goes, so that you can tune your tune to one properly. Because you don't want two pulses happening at one time, right? You want the pulses to come in staggered, so the one pulls or pushes the other. Normally we'd You don't want to push. Because for every horsepower that the motor needs to produce to push the exhaust out is a horsepower that you don't have driving the rear tire. It'such a large field. But people make the mistake of going too big. So there's that magic balance and that is the art. Science will get you the diameters that you need, will help you with blank, and then it j If you think about it that way, it could be frustrating. I find it fun, but that's my emphasis. I We So just be, it's better to fail at trying a theory and learn from that than it is trying to ask ten people. How to do it? You're going to get twelve answers. My favorite thing is you ask ten people one question and you get twelve answers. So it's much better for you to keep those two in mind, one change at a time, and be happy to fail so that you have some other learning curve. And you just keep stacking it. Give yourself a couple years. You'll have a lot more information. I guarantee you half my competition and half the people out there. Craig, thank you very, very much. It was a pleasure.
