I wouldn't have thought twice as high, as there will be more destructive interference of the sound waves as the number of cylinders increases. One must also consider stroke length and piston speed, who cares anyway I like the sound the little beast makes!
@tpvalley Yes 13,000, don't forget it's a twin so not that high pitched. Standard cam, modified head and CBR250 carbs. I do everything myself, don't think anything is available off the shelf.
That bikes got spunk!

@Kompins A twin sounds twice as high-pitched as a single at the same RPM.. (unless you're comparing it to a 125cc four!!)
