So I'm going to change my oil now, after a question i posted earlier about white residue on my dipstick.
I haven't had the bike for a long time, so I have only changed oil once before. I drained all the oil out, put in half of the new oil, let it run for about 5 minutes and then put in the other half. I also changed the filter. Is this the right procedure?
Also, I read somewhere about a sort of filter inside the frame that needs changing. What is this and where is it?
