Find yourself an engine stethoscope and see if you can identify the area the sound is coming from.

Between the injectors, valves, and all the moving bits, including external stuff like the PAIR valve, there are plenty of sources for minor ticking.


This is usually during the warm up phase so idle is higher. Once the bike is warm I don’t notice it.
