Degrees of ignition advance explained

When you see “+3°”, it means the spark happens 3 crankshaft degrees earlier than stock (at the same RPM point on the curve you’re comparing).

A stator mod shifts base timing across the whole range. A CDI curve can add/remove timing differently across RPM.

More advance can make more torque, but increases heat and detonation risk.

  • Small steps matter: +1° to +2° is noticeable.
  • Detonation = back timing down immediately.
  • Fuel quality and squish/compression control how much timing you can safely run.
