2023 YZ450F turned into YZ350F with Yamaha Power Tuner

Dialing back the 2023 Yamaha YZ450F to 350F using the Yamaha Power Tuner. The app says fuel and ignition settings can be adjusted +-10 steps. To see how much response and power feel could be dialed back I created a map with -10 on both Fuel and Ignition. Wow! Really slows down the engine RPM build and dials back the power. A nice option and kind of like having two bikes in one with the push of a button. Fire breathing 450F moto bike or much slower revving easier to ride 350F.
