It is my pleasure to view, enjoy and comment on your brilliant work. Some good news and some bad news.
Good news is that if there is a healthy oil supply going to the cam shafts, then it is safe to say that the oil is also going to the cylinder walls.
Bad news is that I made my oil testing tool for my Triumph motorcycl back when I owned it sometime in the early 1980's. Since then I moved to many many locations and the tool has been long lost in all these movements. So I am no longer in a position to provide any pictures. If I was in your place, I'd go and buy one a/c gas testing tool. That is the tool the a/c mechanic uses when you go to check the refrigerant pressure in the car. You will end up with most of the hardware already made. The only thing needed will be the threaded connector that will allow the hose to be connected to the bike. your lath shop will be able to manufacture such a connector for you.
Regarding the "chotay chotay kaam" ..... If you have managed to do the "baray baray kaam to chotay chotay kaam bhe ho jain gayy".
Just keep at it and one day it will all be done.
