Points gap — 12.77 sheet

Value
0.35–0.40 mm
Applies · /7 range
BMW-WSM7 Contact spring pressure 450 p. The '79 sheet raises this to 0.45 ±0.05 mm (0.018 ±0.002) — a real change, not a rounding. Dwell is the better check either way: BMW gives 65–68%, printed as 120° ±3° on the '79 sheet (the 12.77 sheet's 78° ±1° uses a different convention and the percentage is what to trust). N/A on '81+ Hall systems — nothing to gap, nothing to wear.
