hey all, im new here, so thought i'd give this ago.
well straight to the point.
i bought a cheap honda rebel 125. to (hopefully learn something) so far so good got it starting etc with a little help from uncle. BUT we have hit a problem. there is a small pipe inside the exhaust up at the flange and it goes down it is sitting around 3 inches in from the flange. problem is it is loose, and no one seems to know what it is. it rattles something awful aswell. so any help from here will be great. and a really good first impression.
also have tryed to pull it. (didnt work)
