Valve seals are not gonna cause that much oil residue to the point that the exhaust pipe seals are leaking oil. Pull the plugs and squirt some marvel mystery oil in there and leave over night. The next day put plugs back in, disconnect the ignition and crank it over for a little to get rid of excess marvel.
Reconnect ignition and start it up. It'll take a little to get all the marvel out. Take it for a good ride then check everything including a compression test and go from there...
If you have more that 200 cranking pressure then maybe on the compression releases.
I'm running 216 ccp and do not use releases...

Not sure what marvel mystery is or if I can get it in U.K.
The oil leakage is not massive in 60 or so miles I've had two thin streaks hit the chrome under the exhaust port now thinking how thin the oil would be when it's hot the streaks in terms of drips would be small.
As for compression releases I'm certainly no expert at all I'm just goin by what me pops said.
Not sure any other reason you'd get this Horrid metal clunk when it doesn't fire.
When it doesn't fire it sounds exactly like this soft tail
You have to understand that the noise is not there at all when the bikes fires only when it doesn't fire. It almost always fires from cold with choke on. When Luke warm it needs throttle.

These may be possible, did dad add oil to the cylinders to store the bike,? Some people did this back in the day, squirted oil in and then reinstalled the plugs.
Maybe your timing is too advanced causing the hard starting like in the video and maybe starter drive is on its way out...also, how good is the battery..

Battery is brand new just replaced it along with new 8.8 spark plug wires and plugs. Gonna change oil tomorow and see if new plugs and lead help it out.
But starter could be on way out. I believe it's the original
Not sure on timing but it rides ok.

you need to slow down some. if i had to guess, i doubt the starter is on the way out. if your bike starts like the one in the video, i would look at the starter drive before buying a new starter. get that fixed first before anything else. as far as oil in the cylinders goes you can use any ordinary oil in there to see if the rings get unstuck. it sounds like you want to throw all kinds of money at it without knowing what you're doing.

My starter sounds like that on a cold unstart, (wouldnt start), dont sweat it, either it starts or it dont, low amp starter will struggle with compression but will do the job. Im just too cheap to upgrade mine. 
When it dies ill get a bigger one. Run it a bit, keep it full of oil and see if the oil seep clears up. Im betting it does, its wanting to be running down the road

Again im no engine expert at all, but i was thinking that oil is being pumped up throgh the push rods to lubricate the rocker arms, it is then seeping through my valve oil seals into the combustion chamber and then being splattered onto the spark plugs
And out through the rear exhaust port.
Again i could be wrong my knowledge isn't great

The internals of an engine are a perfect storm of oil mist while its running, but there are only two routes for the stuff to find itself onto your plugs, through the valves as you suggest, or up the bores passed the rings. To diagnose and fix either or both of those requires removing the heads.....
