HTM - Yamaha ECU Tuning

07/15/2026

I had the privilege of taking a ride in a brand new @ Vexus with a Yamaha 250 SHO that I flashed yesterday at Bull Shoals Lake! What a smooth ride! 😎

We were able to gain a solid 5mph, and few hundred rpm, not to mention the increased fuel economy.

Want more out of your Yamaha SHO?
