MCX Compression Test

Anyone have a step by step on how to do a compression test. I have the pressure gauge, but more wrt the specifics of this engine - how to disable the coil, etc.
Doing some spring maintenance, thought I'd do this as well.
Thanks

Pull the kill switch cord and find the fuel pump relay. Remove the relay and do a normal test.

Yours is fly-by-wire throttle so if you don't have the diagnostic tool to run it in compression check mode you will need to unplug the fuel pump (under rear seat bin) and unplug the coil so you don't have spark. Next put the handle right down as far is it will go and you should find that it will open the throttle plate right up and then you are ready to go.
