yo, first off, try using some punctuation in your post. when you type the whole post as one whole sentence it makes it hard for people to follow. if you want help, use some punctuation..
that said, there is no reason to take off the clutch basket. if there is a piece left in there, its down at the bottom.. check under the basket and in the surrounding area. if you cant find anything there, i recommend draining the oil and using a small magnet to try to pull any loose metal out.
remember, it wouldnt take much for a piece of metal to get wedged in between gears and tear all kinds of shit up.
