This is a must have for all drag racers (car or motorcycle) using a hydraulic clutch system who are looking for that competitive edge.  With the CFM Performance Hydraulic Clutch Flow Control Valve, or HCFCV, that edge is just a button away.  The HCFCV allows for adjustable hydraulic fluid flow to control exactly how hard you want the clutch to engage during launch by simply holding down a switch before releasing the clutch.  After the switch is released all clutch functions are back to normal so there is no clutch slippage through gear changes.  The HCFCV is the answer to stop breaking drivetrain parts when using sticky tires and racing clutches and helps with consistency as well.
