Checking the sliders

- Check that the guide slider and the tensioner pad
are not excessively worn.
- Replace the sliders if they are worn.

Cam timing

The ignition advance is determined electronically on the basis of parameters known by the control unit.
For this reason it is not possible to state the reference values based on the engine revs.
The ignition advance value can be measured at any time with the Axone.
It is possible to check whether the ignition advance determined by the injection system does in fact
correspond with the value actually activated on the engine, by means of the stroboscopic light.
