Frequently Asked Questions

Q: Is this a direct bolt-on upgrade for my YZ65?
A: Yes, the V-Force 4 is designed as a direct, bolt-on replacement for your stock reed cage, making installation straightforward and hassle-free.

Q: Will this improve the bike's bottom-end power?
A: Yes. The improved airflow and efficient sealing characteristics of the V-Force 4 typically result in snappier throttle response, especially in the low-to-mid RPM range where 65cc bikes need it most.

Expert Pro-Tip: When installing your new reed set, clean the intake tract thoroughly. Any dirt or debris left in the intake boot can find its way into your engine or compromise the new reed seal. Also, check your intake boot for any small cracks—if you find one, replace it now to ensure a perfect vacuum for your carb.
