you got to take out the servo, and open it up. Dont try to force it to turn, it will break the internal gear, once you got it open it a sample job to move it.I disconnected the cables by removing the mounting plate at the exhaust valve and pulling them out, thus leaving the settings intact. I could not really tell much difference on a test ride, maybe a little less abrupt ?
However the upper cable is now fully retracted and won't move, and there is loads of slack in the lower one so I can't refit them. Plus the F1 light is on!
The actuating device is buried deep and looks like a lot of work to get at.
Does anyone know how to reconnect the cables?
