When moving the forks up and down on standstill they seem to work fine, it's putting me off going out for a ride. :'( :'(

Make sure no one has put washers/spacers on top of the springs ;)
Trigger what would be the reason for adding spacers on top of the springs ?
The previous owner supposedly gave the bike a full service including new fork seals and oil before selling it to me, so i will try changing the oil to 5w.

The bodgers way could involve stacks of 2p coins.....which gave you a regular size and was...well...cheaper than buying big washers! I found that one first when I unscrewed a top cap and got a surprise shower of small change.

Adding spacers to teh top of the forks is an old-school way of stiffening up the springs. You are basically preloading the spring. It has a side effect of reducing the travel leading to some interesting effects under load and bottoming out if you hit a bump on the brakes.

The mind boggles :o

All adding spacers does is limit the amount of travel in a spring. It doesn't stiffen springs at all. The spring rate is the spring rate no matter how many spacers are put in.
Do not confuse a springs, spring rate with a springs, load/design rate.

Are your wheels correctly trued and balanced ?. My front wheel was not fully trued, it had a flat spot , I have improved it but it needs another go, as does the rear wheel. Making a slight improvement on the front made a slight diffence to the bounce I was experiencing although I still need to properly true them both. I have also picked up some 5w oil which I will add to improve the damping. Like you it puts me off riding the Honda a little, but with some patience I suspect it will get sorted.
That's something i'll have to check.

I'm not saying I have in fact cured it yet as I would like a second opinion on the 're Truing ' of the wheels by someone.
Another issue I guess mentioned by a previous party was that we should not I guess expect too much from these bikes, they are heavy, old tech and should not be compared to a modern machine. I find I am doing this constantly with the ride and the engine noises and quite frankly it drives you a little mad.

Not sure for values of your weight you provided (stone - is that kind of slang, equal to feet of what? Sorry that I don't understand...)
My weight is 80kg (naked :D)

By way of an update, I have just added a 5w oil to my forks and the bounce has in fact reduced quite considerably.

You want to try going for a ride on something old then. ;)

Have the same issue with my CB750K7...Where are you located Erny ? not in the UK i would guess. 1Kg = 2.2lbs(pounds), 14lbs = 1stone, (old british weight measurement). Personally i can't get to grips with a persons weight in kg, too long in the tooth :'( 80kg means nothing to me, i have to convert it to stones to know if you are a lightweight or a fat b*stard like me (16stone)

I live in Slovakia, we use metric system only. I knew about pounds, pint, gallon, ounce, inch, foot, yard, mile.. But never heard about stone.

I must admit though.. I cant visualise 173cm but I can 5Ft 8in... but then I can also visualise 85 or 90kg but have no idea what that would be in stone.. so I guess I am just as bad.. :)

Oh dont get me started on different variations.. I sell pumps (irrigation pumps...big ones) and the mixture of standards I get as enquiries... a bore will give X Gallons per hour while they want X litres per day at X feet of head and they have X metres of pipework... Problem is most Cocky's (Farmers here in Aus) are older guys and still live in the pre-metric age.. or they mix and match.The reason you can't visualise stones is because you live DOWN UNDER, you have to be standing the right way up then it's simple ; ::)
