The process of checking the oil level has probably been described. If not, this is what I do: In the morning, I start the bike cold, without revving, let the engine run for 1:15 minutes, then stop, open the cap, pull the dipstick out a little (so it's cleaner and the oil drips off it) and after 3:30 minutes I check the level.
Now the question for million dollars: How much oil should there be? Some people (including those in the automotive industry) say somewhere in the middle between the marks. Never fill to the top line. My question is: Why not full? WTF is the top mark there for, if not as a full mark??? Because if it's only supposed to be half, the bike manufacturer would put it on that half! Right?
After my last oil change at an authorized service, I checked it the next day and ****, there was almost no oil on the dipstick! I sent them a complaint and a photo, they sent me a 1l bottle and I put almost everything in there to reach the upper mark! Then they apologized to me and said that they changed the procedure and are putting more oil in because they checked that I was really right. But they don't put it all the way to the top, only about 1cm above the lower mark. So I must after each service interval buy next bottle to fill it properly!
Honestly, in my opinion, this stupidity about filling the oil halfway (or only 1cm above the lower mark) is outright theft. With the wholesale price of 1l of oil being, say, 10 euros (even if only 5), and with the production of 3-11 million cars by the largest car manufacturers, we are talking about completely different numbers that they save and pass on to us in small amounts. Basically, they rob each of us of those 10 euros, we don't mind, and they have 30-100 million euros in their pockets. Every year, I remind you. For every one (big) producer. And in smaller money also for each service, because we pay for oil change really big price.
