Battery
Oddjob:
I tend to try and find the original battery as fitted by Honda, see what's it's measurements are then see what available in replacements. In the 500/550 range the AGM batteries are 1mm taller, 161mm as opposed to the standard 160mm. I doubt 1mm would cause any problems. Width and depth are the same.
royhall:
All mine have been specified for the relevant bike and have been between 6 and 8mm higher.

Interesting video - I have read about how to de-sulphinate lead acid batteries previously the video method looks as though it can be dangrerous.
On later smart chargers like my C-TEK there is a Reconditioning mode that they advise you only use once a year on a battery - I belive it uses pulse charging at higher voltages to reverse the effects of sulphination.

When I lifted my cb750 engine out I made a platform just in bit higher than bike frame the put jack under engine with a piece of wood on jack and then slid it out I did it on my own but if you got help even better I left on platform to work on

Neat idea. I have a couple of mates offering to lend some muscle. I'll remove the ancillaries, including the exhaust flange fixings (the parts that screw into the head). But I'll leave in the stator / dynamo, clutch etc. and see how we get on.
Your idea, plus with some 4"×2" strapped to the barrels, to lift it each side, should work. It doesn't matter if I scratch the frame getting it out, as I'm planning to strip it and paint it up. Getting it back in though...!
