Whilst up close to the sump ive noticed a large bolt on the left front side of the bike hanging out, its clear from looking at it that the thread is very worn on the mount and the bolt has been given a chemical metal treatment of some sort to hold it in

After that I noticed a rather worrying lack of bolt at this mounting point again on the left at the rear cylinders

Also spotted a cracked header bolt hole with a missing bolt so one header is held in with only one bolt

Have I been riding around on a deathtrap or are these auxiliary mounts or somesuch? Or is the engine being held in with magic??
was wondering what these mount holes are at the front of the engine, just at the right, beside the header in the pic:
