I threw all my steel offcut bits & bobs about 30 years ago!

I honestly can't remember off the top of my head, and I am not in the same place as the bike now to check.

I think it was M10 for the front and M12 at the back lower mounting points. The parts book doesn't give sizes, but the mounting points I used are shown here:

And the bolts here:

Just see what'll fit in. Length wise, they just have to be long enough to allow you a good hold, so longer than the bolts, but if they are too long, they may start to bend - threaded rod that is.

For supporting an engine without work frame bolted to it, an old car tire is effective to sit it in any orientation.

Who reads a newspaper these days?  ;D ;D

But I like the car tyre idea; never thought of that!

That looks a good way - especially if my brother isn't available to act as a human crane.

Frame over the engine every time makes it a doddle  ;D
