The next problem is that what I thought was a fastener, was just a cap. I can turn it with a big crescent wrench, but the header pipe runs into the carb before it turns very far. I've uploaded more photos at the link below. For what it's worth, the crankcase is stamped "FZ-140 S."<br></div><div aria-label="Compose body"><a href="https://goo.gl/photos/K1VHJ5n5h16aMGHM9">https://goo.gl/photos/K1VHJ5n5h16aMGHM9</a></div><div aria-label="Compose body"><br></div><div aria-label="Compose body">Duane<br></div><div><br></div><hr id="zwchr"><div style="color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt;" data-mce-style="color: #000; font-weight: normal; font-style: normal; text-decoration: none; font-family: Helvetica,Arial,sans-serif; font-size: 12pt;"><b>From: </b>"James Hiller" <jnhiller@earthlink.net><br><b>To: </b>"Duane Beck" <duane.e.beck@comcast.net>, "General pattern discussion" <nsrca-discussion@lists.nsrca.org><br><b>Sent: </b>Saturday, August 1, 2015 4:54:16 PM<br><b>Subject: </b>RE: [NSRCA-discussion] YS 140 Sport stuck exhaust header<br><div><br></div><style><!--

If the socket is metric, try forcing on the closest larger us size. You might also be able to cut a slot in it with a cutoff wheel and use a large screwdriver to get it out.

The socket has been damaged a bit by previous installation and removal, to the point where I can't get an allen wrench to hold tightly. When I try to turn it, the wrench slips.
