1995 MZ 660 tour engine parts needed

[buzzbom]

At worst I`ll need the entire engine and just do a transplant . At best , I may get away with just the left hand crankcase.
I say this because I`ve just noticed an oil leak somewhere behind the cylinder on the left side , maybe just a base gasket ,could be a busted case , although I cant see any cracks anywhere .Hoses are tight and no holes anywhere .
Any engine parts that you may have , which you think may be of use to me , please email , coross@xtra.co.nz
