ACL Motorcycles have heavily invested in the latest diagnostic equipment to help fault find most problems. Some of this kit is shown below (we like to show off).

This is a MAC Scanner. This will read all the fault codes on all modern bikes and interfaces directly to ECUs to analyse faults and errors. If you want a list of all the bikes it will analyse, click here (PDF download).
This is a fuel pressure tester. It's amazing how many fuel problems come down to low or non-existent pressure. This is the ONLY way to safely diagnose this.
