How do you set timing on a 79 Ironhead sportster with points and condenser?

To set the timing on a 1979 Ironhead Sportster with points and condenser, first ensure the engine is at top dead center (TDC) on the compression stroke for the front cylinder. Remove the timing plug and rotate the engine until the timing mark aligns with the mark on the engine case. Next, loosen the points plate and adjust the points gap to 0.018 inches, then rotate the points plate until the points just begin to open at the timing mark. Finally, tighten the points plate screws and recheck the timing to ensure it’s correctly set.
