I would not put much load on holes 1 and 2 (as in engine mount). They are in the alu front cover and I centainly would not hang my engine on that.
Holes 3, 4 and 5 should be fine for engine mounting.

On the "where does this hole go" I would like to know
where the lower left hole of the side engine mount
hole goes.

On the "how far setback" I am contemplating using
these holes as part of an engine mounting point.  I
was hoping somebody had already gone this route and
had determined the offset of the front cover bolt
holes from the end housing holes.  

Thanx...
