I am struggling to find the cause of the following error codes: Front Injector low Rear injector low Front combustion Reading these forums I have gone through the injector wiring and cannot recreate the fault. I purchased the new HD Code reader which is actually very good. The fault only comes up when the bike is moving usually between 25-45 mph. If I slow down for stop sign etc it goes away but then the light comes back on when I get up to a steady speed. Checked plug wires and also replaced voltage regulator. Cannot recreate unless riding the bike! Thanks for any thoughts!
