I think you've missed the point of what people are trying to say. (shocking)
Take the advice of arsey30.
There are very few 'broken' engines, most will have some useful parts, which is why I don't think you will get one for free.
If you want to see how things go together then look at the microfiche, that is what it is there for. Then buy a bag of nuts and bolts.
All stripping an engine will do is let you undo many bolts.
Without taking things apart with the view of repairing / overhauling something you won't know if you have fixed it or made it worse, hence not learning anything.
Your engine doesnt need stripping and rebuilding so stay away from it, I estimate that a simple strip and overhaul will cost at least 500gbp, if you take into account gaskets, valve stem seals, bearing shells.
You will also need specialist tools to take the engine apart.
Take arsey30's advice as he knows an awful lot, practice your service and maintaiance, oil and filter, cable adjustment, chain slack adjustment, cleaning and lubricating the bearings in the rear hub, adjusting the head bearings.
Instead of paying some shipping for an engine do the sensible thing, buy a decent set of feeler gauges for valve clearances, maybe some decent single spanners like 10mm, 12mm for adjusting nuts.
If you have the above then some decent oils and greases for lubcricating things.
Strip and clean the rear hub, lubcricate the chain and check the cables are clean and adjusted, learn how to change front wheel bearings without knackering them.
Strip and clean front forks / oil.
This is the kind of stuff that will give you a good reliable bike that is safe and not likely to break down, working forks, cleaned and lubricated parts with good bearings.
An old engine in pieces will not help, most VFR engines providing they are maintained regularly will easily cover over 100,000km before needing any internal work.
