same mine always has a little extra in better to be safe then sorry and dont get to much in my airbox either

Good grief what a sad story, if the dealer do not check the work of their mechanics then the fault is always of the service manager. I seem to remember that my old Honda 750 was also dry sump but I used to check the level cold, but the dip stick was in the engine and not the oil tank???? Anyway good luck......

On my XT600 the oil level didn't show on the dipstick at all when cold either, but I did maintain the correct level when warm. So what I used to do with it on an oil change, was empty the basin I drained the oil into into a measuring jug, then pouring from the jug into an old oil bottle for disposal. That way I could measure exactly how much oil I had drained out. Then wipe the old oil and any particles out of the measuring jug with kitchen roll, then use it to measure out the amount of clean oil going back in. That way even though I can't see the level on the dipstick I know that the level is approximately the same as it was before I drained it. There was always a drop lost in the bottom of the basin or soaked into the kitchen roll, but it was near enough to go for a ride and get it hot, so you could check it properly.
