Copperglobe, The BRP is a dry sump system. Oil will collect/pool in the casing when the engine is shutoff. This means that the oil must be pumped into the circulating system. The frame is part of that circulating system. Until the oil is pumped you cannot get an accurate oil level reading using the oil dip stick. When you change the oil and filter, you can add the first quart of oil normally. Then you must use the kickstarter to circulate the oil before adding the rest. Use the decompression lever and gently cycle the kickstarter several times, then add a little more oil and repeat. Do this carefully or you will have oil all over the place. Put in the recommended amount and start the BRP. Let it run 5 minutes and check the oil level using the dipstick (threads sitting on top of the hole). Do not top-off the oil without letting the engine run first (circulating the oil) or you will overfill the system. Overfilling causes excessive oil pressure. Recommend you change your oil after 100 miles. Mostly to remove the milling flakes that will come loose during your breakin period. The high-frame oil screen will catch most of this. The real fine stuff will be trapped by the oil filter. The screen in the bottom of the casing rarely sees any debris. This screen can be left alone for several oil changes.
