[NSRCA-discussion] YS 140 Sport stuck exhaust header

[Duane Beck]

The pin punch worked well. Thanks for the suggestion. 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."

Having a similar problem with many head bolts over the years I found that a solid rap top the head of the cap screw with a pin punch with a light ball peen hammer usually loosened them.

Here's a photo of the header, showing the mangled fastener.

Couple of possible options. 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. A photo for all to see might help with ideas.

I have a YS FZ140 (Sport) that has an exhaust header attached with what appears to be a 10mm socket cap screw, or similarly broached fastener. 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. Any suggestions for how to remove the header?
