75 CB400 "Dad's old bike" project
mike the bike:
The easiest way to get engines in and out is to make a little table from MDF the same height as the frame tubes.
To remove the engine...
Make sure the sump and oil filter housing are removed.
Place the table on the right, as close to the frame as possible
Jack up the engine and place two 2 foot lengths of hardwood, about 20mm thick, under the engine. This allows the engine to clear the lower engine mounts.
Slide the engine out onto the table.
Dead easy, piece of piis.
Nice size workshop you've got there, I'm well jealous.

That's info I could have used 24 hours ago, Mike. ;D
I'd love to say the workshop is all mine, but I only rent the bit my car is shoved in, I just sneaked the bike out into the open whilst some folk had their stuff out of the way. It's very, very dusty and very cold, so I'm on the lookout for somewhere else, but it's been a Godsend today to be able to walk round freely.

When the time comes put the engine back in, you know how it's done. Just don't mix up the lower engine bolts.

I am enjoying watching this build, keep up the good work and the pictures coming. If you think the 400 is a heavy engine, wait till you get to lift a 750 out. :o

Brilliant account of how you're getting on and something to look back at when you get to ride it.
Just a bit to add to the ad-hoc approach, a friend of mine always uses a slab of that rigid building insulation instead of cardboard as if you drop something like the engine it won't snap any delicate bits like fins off it.
Also if you need to support the engine at any angle for storing or dismantling then an old car tire let's it sit securely at any angle you need without toppling over.
I've two kids and don't think you can beat doing anything together really, I remember alot of stuff the same with my father and the fond memories it brings.
You're doing a fine job, it'll just take time to work through it but well worth it in the end.
