The balance and cam timing points and installation for the Yamaha YZF-R25 are described as follows:

- Balancer Drive Gear: Align the balancer drive gear between the projections on the lower side of the timing chain guide.
- Timing Chain Tensioner: Ensure the timing chain tensioner rod moves in and out smoothly. Replace it if there is any rough movement.
- Camshaft Installation:
1. Install the intake camshaft sprocket and exhaust camshaft sprocket.
2. Ensure the exhaust camshaft is identified by the groove on the camshaft as shown in the illustration.
3. Position the cam lobes as specified in the manual.
4. Tighten the camshaft sprocket bolts to the specified torque (20 Nm or 14 ft·lbf) using the rotor holding tool.

Proper alignment and torque specifications are crucial to avoid engine damage.
