I have removed the sump & oil pick up strainer all of the upper engine brackets are out. I have undone the rocker cover bolts in readiness for engine final stage lift out.
Engine is now being supported by what looks like one long rear lower shaft plus a pair front lower bolt(s) that appear to screw into the engine separately?
I have lots of blocks of wood if I need to do some sort of support when I remove the last bolts.
Bearing in mind the lifting of the engine itself is there a good way/order to remove the last of the engine support bolts

I prefer to remove the cam cover, cam, head and barrels while the engine is still in the frame - makes it much lighter and stops it wriggling around when removing the head bolts. After that, the two front bolts with the sump resting on a suitable wooden block.
Then the remaining long bolt at the rear - usually the top one for me.
Very important: the lower front bolts are different lengths - the longer one MUST NOT be fitted at the side where the main oil gallery plug is - it WILL puncture the case.

Thanks for the tip about the lower front bolts I will be sure to label the bots when I take them out.

When the time comes to putting the engine back in your shinny newly painted frame the best way to do it is to place the engine on its side and place the frame over it. You need to leave the sump off, I replaced the sump pan before taking the photo. Keep the sidestand off as well until the engine is in otherwise it gets in the way. If you put the forks and swing arm on before placing over the engine you can pop the wheels back on whilst it's on the floor and lift it up as one complete unit.it is a two person job though but much easier and no chance of damage to the frame paint.

Another great tip thanks. Ted

I used a length of M10 (or was it M12) threaded rod through the mounting lugs front and rear. With a strong assistant it was quite ease to get the engine out and in.
I had to jiggle it a bit taking it out, so left off the rocker cover and breather when reinstalling it and wrapped some bubble-wrap around the frame, just in case. And of course left sump off too.

no need for wood block engine is wider than the frame so it will rest on the frame

I like that method - sort of lifting it out with stretcher handles.
