Now, about the method of exhausting around the baffle…
Failure! It got really quiet, but it’s too restrictive—when the Akrapovic revs, it swells up and the exhaust pipe looks like it’s about to blow out.
It was vibrating like crazy before… and it won’t rev! Ugh, this won’t work.
For now, I’ll add an exhaust port to the center of the baffle too!
For now, I’ll drill through it with the biggest drill bit we have (13.5 mm)!
If this doesn’t work, I’ll have to expand the inner diameter on the lathe…
Let’s see!
Vroom vroom vroom vroom!
That’s a pretty nice sound! Let’s try it!
Roar! Roar! It revs! Perfect!
Sound level measurement… 107 dB at 4500 rpm…
Not bad! I’d like to ride it now, but there’s no seat rail…
