This is for an 04 sportster 1200 conversion with hi flow intake and exhaust
getting pinging under load
i am on the highway a lot and thought installing a cooler plug wouldn't hurt. Was surprised to see this
Am going to start tackling jetting. Timing is fixed so may need to shell out for an aftermarket module
