Thank you for your interest in Dynatek ignitions. Depending on the year and model of your Harley you may need to add a mechanical advancer like the one shown here- American Prime Manufacturing Inc. Comp Master Advance Unit - APM-1104-0001 | JPCycles.com. You may also need to change the coil to a 5 ohm one like our DC7-1. If we can be of any future assistance please feel free to contact us anytime.
