Yamaha - Shifter Gear Selection Mechanism 6E5-45641-03-00. Overview. When shifting isn't crisp, this is one of the components I start looking at right away. The shifter plays a direct role in how smoothly the engine moves in and out of gear, and even a little wear can make things feel off. I've worked on setups where a worn shifter caused hesitation or rough engagement. When everything's tight and working right, shifting feels solid and predictable every time..
