Your dream or possibly nightmare just come true!
A genuine 1980 900SS for restoration, It came to us just like this but will be sold with a full set of serviceable desmo valve gear and all the parts you see in the pictures so you won't have a massive list of missing unobtanium to find. Imported by us from France it has no documents but we've taken care of the NOVA so UK registration should be quite straightforward once it's in an MOTable state. If you're purchasing from abroad it will come with a bill of sale.
Dont ask us why anyone would do this to their cylinder heads we have as much idea as you! it's a relatively easy welding job to fix though.
