SR50 with Aprilia/Morini engines are having an electrical oil pump which needs to be bleed differently than a mechanical pump. When you are rebuilding it, if you missed oil or you are changing the oil hoses, this should be done to keep your engine alive!
Rear fairings need to be off the scooter and you oil tank should be full. 1: Disconnect the larger oil feed line on the pump if it's not done. Let the oil flow till it spill out of the oil hose then reconnect it on the oil pump. 2: Disconnect the oil feed from the intake manifold. 3: Apply full throttle then put the key at ON position. Don't release throttle until you hear the oil pump. 4: Wait until the oil spill out of the hose that goes on the intake manifold. 5: Put the key at OFF position and reconnect the oil feed to the intake manifold. Wipe any oil drops on the floor or on the scooter. 6: It's done!
P.S. don't do like I've done on this video: don't let the pump take all the air out of the oil feed line from tank as it will take FOREVER ! The video is just to show how to activate the oil pump bleed. The pump may stop after some time. Just turn the key off, make sure there is no air in the oil feed line (from tank) and that the oil line from tank is not bent/clogged somewhere and restart from step 3.
Hope it helps !

Fox: Anyone who is logged in can see it but it's down at the bottom so most have either chosen to ignore it or haven't discovered it yet.
