I can't say I agree with some, and do with others. In my professional opinion, too much oil is just as bad as too little. It'll hit the crank counterweights causing air bubbles to form in the oil and subsequent air back into the oil system and components - THIS IS BAD. Too low and it can cavitate the pump and even worse air. I think the best oil level is in the middle. Now to check it properly, you must run the bike until pressure builds after it's changed, to fill the filter and nooks and crannies. Then the dipstick is to be unscrewed, wiped and reinserted but NOT SCREWED IN with the bike perfectly level and upright. It's best to check it cold, atleast 10min after running it. This way the oil can drip from the head and crank back into the cases. You'll find that if you check it right away then again after 10min, it can rise as much as 1/2 litre in some vehicles (this info applies to cars as well).
