What is the proper oil level on a motorcycle?

I have an 06 Suzuki SV650s and I just did an oil change, well the manuel to my understanding says to fill to the top line on your oil window. I did this but when the engine is running and you look into the window, you don't see any oil. So should you be able to see the oil in the window when the bike is on and running?What is the proper oil level on a motorcycle?
Turn the bike off first.





Lean it totally upright, then fill it to the line in the window. It should say how many oz.'s it takes in your manual too.





The problem with filling it when the bike is on is that your oil is being spun up into your head and crankcase, so it's not a valid reading-therefore you'll overfill your engine with oil!What is the proper oil level on a motorcycle?
run engine for a few min to get oil into the head then turn engine off , with the bike on the center stand check oil level,top up if necessary.


you will not really see the oil when the engine is running,
I usually dont see any on mine. I think its because of the running bike has oil pressure so I think thats normal or else both are bikes are messed up :)
Your not supposed to check the oil when the engine is running. Stand the bike straight up with the engine off and look in the sight glass. The oil should be at the top line. (engine should be warm when you check it)
