KLX 300 S / SM reprogramming. Nothing can compare to the power it provides. Nothing.

It's almost done. Here is an idea of how good our ECU reprogramming is for the 2020-24 KLX 300 S and SM models. Anyone can add fuel, but we fix the ignition timing and open the secondary throttle plate with thee ecu. No need to take that out. 6 hp gain for less than $400 and it's quiet

My first bike was a 97 klx 300. Had a full pipe and a 36mm mikuni pumper, it was a beast. Can't believe they are still making this ancient motor.
