Description
Honda upgraded valve springs for OEM cylinder head. When running OEM or aftermarket camshafts this will provide a safe increase for RPM limit.
This HD Valve spring kit will support RPM up to 12,000RPM unlocking an additional 20% more overrev over the stock RPM limit. This allows a shorter gearing setup to really help get out of the idle-3,000rpm range where the semi auto clutch is engaging. All while allowing more top speed in every gear.
Highly recommended to be used with larger diameter exhaust.*USE ONLY 1 INTAKE AND 1 EXHAUST SPRING, OEM SPRINGS REMOVED COMPLETELY.
