You are 100% correct. I’ve made several pipes . Each used the same formulas to determine all of the dimensions you described. No pipe is universal in my opinion. You’re spot on. Two stroke tuners handbook has the formulas. Great video
Dude that setup is absolutely sick! But yeah man absolutely in the 2 stroke world people were actually trying to squeeze the berry for all its juice they’d have a pipe built to the actual spec of the engine. If you weren’t totally worried about fit then you’d have just an elbow and a straight cone. Unfortunately these AM parts companies have to make them fit on the chassis. There is sooo much to pipe building. I love your style of building.. People need to pay attention to your vids. This is the real real
Comes down the timing of the sonic wave in the pipe going back and forwards on each stroke .If you don't get that right, the pipe will not work right at all rpm’s. One wave helps drawing fuel in the chamber, and the other wave seals the exhaust port, stopping the fuel mix from going in the exhaust pipe. It's called pipe timing.
