Hi All!
I'm relatively new to motorcycle maintenance and am in the middle of replacing the push rod seals on my 1974 R90/6. Once I got down to the cylinder and cylinder head things started to look a bit carbonized (see attached pictures). Is this something that should be cleaned up? If so, are there any recommendations on how to go about doing it? Thanks!
