You will have to do some math to figure out the Duration- the amount of degrees each port is open- and then you are *almost* ready to plug numbers in to your software. Continue rotating, taking note of when the ports open and close. Make a note of which port is opening and the degree at which it opens. Rotate engine slowly in the direction it runs until you see the top of one of the ports. it doesn't matter where the wheel is oriented, as long as whatever it is oriented with is pointing at ZERO. Attach the Degree Wheel to the flywheel, and align it with something on the engine or use a laser like I did. Set the engine at Top Dead Center (TDC)- meaning the piston is all the way to the top of the cylinder as far as it will go. Remove the engine side cover over the flywheel. You need a degree wheel, which you can print from here: Here is a VERY basic rundown of what you need to do:Д«efore you can start at all, you have to know your port timing. You will have to figure out all of this information. You have to know a lot of things about your engine- port size and location, port timing, desired application, etc.

I'm not going to go into great detail, but you can't just build a pipe and throw it on there expecting it to work well. Someone who knows what they are doing, so you can ask questions! In my case, that was The Book Two Stroke Performance Tuning by A.

I tried a few free ones, but the first attempt at making a pipe from those didnt work so well. Cost $20.00, came with a 4T header design program and a cone printing program that breaks large cones up to fit on 8.5x11 pages you can cut out and tape together.

2 Stroke expansion Chamber Software- I used 2 Stroke Wizard by Build and Click. Grinder and/or file Other Usefull Things: Welder (something capable of welding thin metal!) and related supplies- wire brush, clamps, gloves, helmet, safety gear, etc. Box and Pan Brake (could just use stake table but.) Measuring & Marking tools- marker, scratch awl, steel rule, dividers, etc Safety equipment- safety glasses, ear plugs, gloves, etc. LOTS of welding rod- I used a 110v wire feed welder Cold Rolled sheet metal- I used 18 gauge

Ability to use expansion chamber design software (OR, be really good at math or want to build 50 different pipes (trial and error)) Understanding of and ability to use Shears, Brakes, and other metalworking tools There are alternate ways to make pipes, which I will discuss at the end of this instructable. I'm lucky enough to have access to a shop that has everything I needed. It requires a lot of big, expensive tools. I think there is an easier way- done by cutting out two sheets in the correct shape, welding the edges, and the pumping ultra high pressure water in to 'expand' the pipe, but I didn't have the tools at the time to do it like that. Please note, this is NOT the only way to do this. I dug it out of storage a few years ago and began this process, so follow along as I make mistakes and learn a thing or two about building your own expansion chamber! found it in a grain bin around '95, back when I wasn't allowed to have bikes. This Piece Of Junk was (and is) my first motorcycle. I've always wanted to build an expansion chamber. That's a very loose explanation, but there you go. Check out this link, it will make a little more sense.ДЄnimation of Two Stroke expansion chamber: ДЄs the pressure wave reflects back, it has a similar effect to turbocharging or supercharging a 4 stroke- it rams fuel and air that leaked into the pipe back into the cylinder under higher pressure, causing the motor to have more power (more fuel & air = bigger bang). A tuned pipe has a set of cones- Divergent (meaning the cone gets bigger) and Convergent (meaning the cone gets smaller) that are built to cause 'echoes' or pressure waves to reflect back, which if done properly can increase the power of the engine. The way a two stroke motor works causes them to be fairly noisy and a bit inefficient. There are many ways to boost the power, one of which is by installing a 'tuned' pipe. They are so simple and fun that I've always enjoyed tinkering with them.
