Howdy! I'm Chris and I own a 2025 Kawasaki KLX 300. It's a turd from the factory and only makes 23 HP stock due to the emissions. It uses a secondary throttle plate to detune the midrange, a PAIR valve that dumps air into the exhaust port, making it run hotter and skewing AFR, and it pretty much runs stoich everywhere in the rpm band based on how white the spark plug is. The only aftermarket standalone ECU for it is an APITech Standalone 8.9 from Thailand. This makes life hard. I bought these courses to make life a little easier. Thanks for the help.
