Im guessing its the choke thing.
Change the oil FYI. Now that it has some time on it its a good idea to get all the metal out of it.
"I followed a break in procedure of letting the bike idle for about 30 min then cool all the way down till I could touch the cases before starting the same prosecure once more"
The surface of the rings and bores is microscopicly rough and need to be worn. In order to make them wear you need the rings to push against the bores, so you need gas pressure.
The theoretically correct way to bed in rings (lowest leak down) is to start riding immediately, constantly varying throttle and rpm until operaring temperature. Then full throttle burst, preferably in high gear from as low rpm as it will pull, for about 3/4 of the revrange then snap the throttle shut to engine brake which draws up excess oil in the bores. Do this 3-5 times and go ride.
Seems to be a lot of different theories.
