My Satchmo is Always starting fights with his brother, and he does not play friendly! When he does it I grab him by the scruff of the neck and carry him into the spare bedroom, whilst saying 'NO' in a strong, loud voice. Then I shut the door and leave him there in 'time out' for about 10-15 mins. When I let him out I will put him next to Kitchen and stroke them both for a moment or two so they know they are both loved. I think in my case it is jealousy between the two. Since I've being doing that Satchmo is not nearly as bad with his attacks!
Your kitten may be suffering from an excess of energy, for which the time out is a good idea. Or it maybe the age old instincts (like Lions) where the young, healthy male forces the old, past his prime male out of the pride :( Either way, you need to show the young'un that his behaviour is not acceptable, and cats hate being ignored.
