The GX390 cam, and stiffer valve springs. A header is the first thing you want, and maybe the GX390 carb. Or better a aftermarket carb.

i kinda wanna trade it for a smaller engine to fit my bike. so if anyone around here has a modded clone or nice tecumseh 6hp+ flathead let me know. if not i will see what i can do with it, but reality is starting to set in lol and i dont have the patience
