ORDER PART NUMBER: 0917 for 75cc Combustion Chambers

Note: Hydraulic roller cams typically experience valve float at 6200-6400 RPM because of their fast ramp rates. We suggest you upgrade your springs to AFR part #8605, 1.290 O.D. with higher spring pressures and use our Patented “Hydra Rev Kit” to reduce chances of valve float associated with RPM 6200 or higher.
