This is great information. Thanks for sharing!
So, as I understand this,
250 EFI stock ECU bored to 300 while using the 270cc injector should work as desired. And makes perfect sense!.
300 EFI stock ECU bored to 351 while using the 270cc injector should work as desired.
Assuming KLX 250 and KLX 300 have same injector stock, just different map in ECU.
If this is correct, it makes this so much easier.
If I am wrong, please correct me as to where my mistake is.
Also, how do we data log this bike?
I have a wideband afr and would like to log afr vs RPM vs throttle position.
Thanks again!

Guess it is not that easy,
you need to make trail and error.. If it is not working get a bigger fuel injector.. like 300cc or 330cc or so..
let us know your result.
