Hi Leigh,
Its a low oil pressure buzzer I setup, just a hobbs style switch and a really loud (really loud) buzzer so I can hear it over the engine and helmet and not look for lights or gauges. I think I had it set around 15PSI.
The reality is with the wet sump you will have issues with braking and oil pressure which is "ok" but you want to make sure if comes back on with the power.
Cool video......whats the audible warning thats going off intermittently during the run?
