Valve Lift .630 – .630

The W-9B is known for its strong mid-range and top-end power, while the W-6 is known for its strong low-end and mid-range torque. The best choice depends on the rider’s power delivery preference and the specific engine design.

Wood’s W-9B Camshaft:

Strong Mid-Range and Top-Range Power:
The W-9B is designed to deliver significantly more power and torque at higher RPMs.
Higher RPM Range:
This camshaft is better suited for riders who prefer higher RPM and want a more aggressive power band. Potentially more aggressive idle:
Due to its longer duration and overlap, the W-9B can have a slightly more aggressive idle compared to the W-6.
To maximize its potential, the W-9B may require a higher compression ratio, typically around 10.5:1 to 11.0:1.
