Sorry but this actually does not work for a dry sump engine. The oil level in the tank where the dipstick is located, after a few days sitting. will be significantly lower than it was when you finished riding. Two things contribute to this, the temperature of the oil changes the volume of oil in the system, IE oil expands, and not by a small amount, as it heats from 50degF to 250degF. The second change in measured oil level is because oil slowly leaks back to the engine sump from the tank. This is much different than a wet sump engine like most automobiles where the oil simply drains back to the pan at the bottom of the engine. In a dry sump system, the oil tank is not the low point where the oil drains to over time.
All this aside, the BRP Spyder owners manuals used to have 2 procedures for checking oil, one cold and one hot and it cause lots of confusion. I can tell you that a Spyder (998 or 1330) that has proper oil level at operating temp will be just at the bottom of the dipstick when cold. Not an exact measure but its great for a go / no go for a ride.
