The official line is that you should not split the brake caliper into two halves. There is a rubber seal between the two halves and Yamaha do not supply a replacement.
If that inlet valve clearance of 0.07mm is correct then it is well below what it should be and I would bite the bullet and put it right. It would be worse if it was the exhaust that was tight be still not good.
One of the carbs coated in oil/crud could be a small oil leak after previous work or maybe a leaking carb. Give it all a good clean and then see if you can spot where it is coming from.
