Than 2 strokes right?
Guy out of portland is a KX500 guru and has been dynoing all sorts of configurations.
This is his latest. 2019 YZ450, I believe stock in blue.
Dinosaur KX500 with an induction crank and lower port timing, also jetted correctly. Other than that stock in red.
Also just a smidge of hp difference
