I am new to these bikes, so someone please correct me if I'm wrong- but, as far as I know, this muffler will fit any K100 from 1986 on. It won't fit my '85 without modifications, which is why I'm selling.
Seems to be in great shape, no dents, no cracks, nothing rattling inside. Heat shield paint is pretty nice.
$100 plus shipping.
Thanks,
Andy
