The black is normal. Looks ok from what I can tell.
hahahahaha 1 inch he says

EDIT: whoops forgot i was on my gf's cpu
Yeah I tell my wife that it's 12 inches all the time... it's ok to strech the truth.
normal. The black ring at the top of the cylinder is because the rings on the piston do not reach the top of the bore.
looks like someone was burning gasoline in there.

LOL..that was pretty funny!

"Oh no, not the 1" down black ring"!!

Looks like your going to have to replace the crank, flywheel, cylinder head, and rear fenders on the bike.... hehehehe

Just take a scotch brite pad or brillo pad with some water and soap and rub that carbon away.
