Yo! Have a bit of a wierd one going on with id'ing a slabside 1100 engine. Been loaned a 1052 motor, however the displacement has been scrubbed off the barrels and the crankcases are stamped beginning with N, which translates as a 600cc engine. The clutch cover casing has 4000ml for the oil capacity, whereas my 1052 motor has 3300ml.
The cam cover breather exits to the left on the loan engine and a slabbie on the right of the cam chain tunnel facing rearwards.
Sprocket cover looks slabbo, but the sump pan oil cooler ports exit at the front of the sump on this one, not the underside as per 1052.
The carbs that came with the engine are 38mm, way to big for a standard slab. assured engine was 1052, but having doubts.
Any other info to help ID would be greatly received.
Cheers.
