I’d somewhat suspected TPS but my continuity checks appeared to rule it out. Igniter connections, can’t quite remember so will check.
How did you do the continunity checks of the TPS? Did you do a rotation test on it?
The Tachometer error codes are not foolproof as they only react to three conditions Disconnected, Short Circuit or Locked in position.
Ufortunately they fail due to wear which causes the TPS to disconnect and reconnect quickly internally at certain rotation, but the ignitor reacts by changing the timing suddenly thus causing the surging. The disconnection of the TPS tracks are to short for the Tachometer error codes to show.
Since your bike is Ivanised and if it is surging then it would be caused by a failing TPS.
