I've acquired an early '86 R80GS motor which the unknown PO had begun to rebuild with a 1000cc big bore kit. I am trying to ID the maker of this kit. It could be Siebenrock but doesn't exactly look like the pictures on their site. It has a mark which resembles a dollar sign with the right hand vertical slash mark being 'C' shaped. See attached pic and please let me know what I've got. Not sure why I can't upload more than 1 pic but will try via answers.
