A leak down test will test the sealing on the Rings as well as both inlet and exhaust valves, Carried out at TDC on the compression stroke.
Ideally you would carry it out at 100psi so as to get a percentage reading, but I find 60psi to be better as you need to lock the engine at TDC with a bit of wood between the swingarm and rear wheel as even 60psi would spin the engine over
