I especially like that it does not have a separate head; no head gasket. The hard plumbing of the fuel line and air line behind the front engine plate speaks volumes of its dependability. This Fastwin was taken care of and properly stored. Thanks for posting the parts manual.
Parts list calls for 2 different versions of crank pin rollers. 50 on the early and 100 on the later so double row on the later? Mine is the early version.
