Hi guys,
I dropped my bike to mechanic for oil change. Had fresh Motul in it, but wanted to go back to Shell advance, which is recommended in manual.
It surprised me that mechanic didn’t position bike vertically to let all the oil inside to drain.
When he filled in the new oil, the oil in window was still green (Motul). He told me that it is normal and certain amount of oil ( about 200g) will stay in there anyway. He also says that nowadays it doesn’t matter which brand you are using, there is a standard for oil production which makes them all to work together.
Today after short ride I inspected the window and there was some bubbles in it. I have attached photos. Is it normal? Also the oil level was above max in fact it covers all window, but I guess that is because of hot engine. Tomorrow I will check the oil level again.
I realize that this questions may seem foolish for somone, but I need to make this thing clear to myself.
