Recommended for use together with racing camshafts, the adjustable timing gear from UMA Racing allows a range of 5 degrees ignition timing advance/retardation for fine tuning to suit your specific performance tune.
An adjustable camhaft gear will allow you to move the powerband up or down in the RPM range without using a mappable Cdi/ECU, and allows for easy ignition timing tuning to suit your specific riding requirements. As a general rule, to improve bottom end power advance the timing, and retard timing to move power to top end RPM.
