High RPM Valve Spring Upgrade Kit

$39.99 $49.99

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.

Amazing

There is good reason many places will refer you to CJR for flashing services and parts. Cameron was super helpful and answered all my questions. I needed two CRF125’s flashed and back to me in a hurry!!! After speaking on the phone they were back in my hand three days later, and I’m on the west coast. I can’t say thank you enough Cameron for your help and expedited service, I will definitely do more business with you and send anyone I can your way 👍🏻
