Fill Up The Oil Filter With Oil Before Installing
The CBR500R oil pump seems to take a (worrying) long time to circulate after an oil change with new filter (suggesting slower oil flow, compared to a car); the oil pressure light stays on for a long time that is.
I found a cure.
Fill Up The Oil Filter With Oil Before Installing It.
I fill the oil filter fully, wait for it to soak through, fill it again until it is full of oil.
When installing, get into position, tip it slightly and screw it in. Surprisingly, no drips!
When starting up, the the oil pressure light goes off a lot quicker; 3-5 sec i think (i did not time it).
