I really have to thank you Sr.KXRdr, the torque values for the cylinder and jug were important! My dad and I had to make a tool though to reach the bolts, I'll get a pic of it soon.
Here is something I typed up for some friends:
"First I drained all the oil from the crankcase, put the bolt back in, filled the case with fresh oil and swished it around. Then I drained that oil and did it again. And again, and again and yet again until no water was present in the oil.
Next I took off the plastic, you know, side panels, shrouds, tank. Then off with the sub frame.
Next I took off the carb and set it aside. I put all bolts I took off into labled plastic bags, so I don't forget where they go.
I then drained the coolant from the bike and took off all the hoses, and then the rads.
Once all that was off I took off the pipe and then went on to take off the cylinder head and then the jug.
Then off with the piston and the top end bearing and put them aside.
Now there was a LOT of sand in my lower end. Along with water. So I filled the lower end with alcohol and then sucked it out with a little hand pump. After the alcohol I flushed the bottom end with kerosene several times.
After that I had at it with a can of WD40. I sprayed it everywhere in there! It does a great job of getting the sand out. So 2 cans later and about 5 more kerosene flushes the bottom end is clean, I coated the parts with a little 2-stroke oil and covered it all up with a few clean rags.
Next came the cylinder jug... I hit it with some B-12 chemtool to break down the oil and get the power valves cleaned out. I then filled a bucket with hot soapy water and stuck the cylinder in. I have it a good washing then hosed it down with clean water. Then I dried it off the best I could and hit it with the WD40 to drive out all the water.
I did the same with the head, making sure to clean out the spark plug threads with an old toothbrush.
Then I got after the expansion chamber with some Castrol ‘All wheel cleaner’ and a scotch bright pad. Gave it a good scrubbing and then washed it off, again I used WD40 to drive the water out.
I then also cleaned the plastics, re-sealed the airbox and painted the sub frame."
