High RPM Valve Spring Upgrade Kit

Extremely fast shipping

Was a pain to install, like all small valve springs but was well worth it!!!!

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 👍🏻
