Clearly on the nearside there was what could be described as a pressing around the holes, a little like a cup washer. I can easily make a suitable repair.
On the offside I presume the holes where just plain holes and the protruding metal visible in the photograph is just from damage or movement of the rear fork bolt at some point?
As both the engine mounting bolt and the rear fork mounting bolt both need to be tight it is important the dimensions of the mounting holes are correct. I have established that all the correct spacers and washers are present bar the rear fork bolt locking piece.
I would appreciate confirmation of what I believe the frame holes should look like.
