Roxburd. I have to say that, after adjusting the pulley cable on the Exup (initial indication of Exup fault on the speedo - 0 to 7000rpm), the fault persisted. I was impressed how the Exup operates directly proportional to the amount of throttle given - but it moves gradually rather than a sudden leap open/closed. It can be heard snapping back closed when I hit the kill switch. I didn't notice any change in performance after this adjustment. Given the state of my plugs and balancing, though, it's no surprise.
The signs and symptoms I got before any remedial work were:
Difficulty starting (not an Exup fault symptom, I understand),
Uneven tickover,
A brief delay in engine revs pick up when revving her up (it was possible to twist and release before the engine revs picked up!),
Holding the throttle open, she ran as rough as a bag pf spanners until eventually picking up and screaming,
Intermittent pick up from low revs (static and moving off), and
Scarily low power, jerking and running on three sometimes, at low revs at any speed.
Now that's all done, I've just noticed the Exup warning again. Grr.. It's coming out this time - the slack cable was obviously not the only thing that needed doing.
