Yes, and no.
The engines we are working with are terribly de-tuned, and capable of much higher rpm, and power.
That's the no part.
The yes part is if EVERYTHING is not done in balance the engine will self destruct. Just like building a cocked building.
It's not rocket surgery but all the parts need to be tuned. Meaning, all sharp edges chamferd. All ports/passages made symmetrical.
If you add a better scavenging exhaust pipe, you need to create a more efficient intake system, and that has to be capable of the proper 14:1 air fuel ratio in the required volume.
It is simple stuff, and everything you need to know is either right here, or hundreds of other sites on the net.
Nothing beats experience from trial, and error so right here i'll wager there is well over two hundred years of combined experience, and tens of thousands of trial, and error dollars. (that's just me)
These small cc 2t engines can add another third as much rpm, and seven times the original power output. Reliably if you treat them right.
