Since this was the first service nothing major was involved excepting an oil change and filter replacement.

The engine oil discharged from the vehicle had its usual share of metal dust. What was heartening was that the oil had not lost much of its properties, difference in volume was negligible which meant no blown oil seals, smelt normal with no burnt tinge to it. However the drain cover in my bike had come without an over ring which was surprising to me. The setup from factory was so good that there was no leaking oil. However the service guy ensured that a new over ring was put in its place. When seating the drain cover in place the filter (not the oil filter) needs to be put properly in place lest it brakes. It did look fragile though and am sorry I missed taking photos of them.

Bike has improved in terms of better ride. The clutch adjustment has made the shifts very smooth. So I believe the clutch needs to be check for any additional play once in 800 kms when the chain is cleaned/lubed. The engine clatter has sobered down and the noises made during the low end of the rev range have eased a bit. Does a single change of oil do so much of stuff?
The service set me aback by 930 Rs with the oil filter, 1.8 Liters of Engine oil, Consumables replaced.
I will have another replacement of oil and oil filter once the vehicle does 2000 Kms. The stipulated second free service is at 5000 or 6 months whichever is earlier.

I cannot explain the missing O-ring in the cover but the fact that it did not leak oil says a lot about the quality of the parts machining.
As a side note, I once owned a 1958 Mercedes Benz 220 sedan.
The engines oil pan, a aluminum casting that covered the entire bottom of the engine was machined so well a gasket or sealing compound was not required.
In fact, MB did not even sell a gasket for that joint.
Getting back to the O-ring, as long as the O-ring and the adjacent surfaces are totally clean and the O-ring has not been damaged by someone trying to remove it it should last for years, even if the cover is removed at each oil change.
I intentionally did not change the O-ring seals on my 2011, Royal Enfield G5 (Electra), 500cc, fuel injected UCE oil filter cover and oil pump inlet screen cover for 4 years and 15 oil changes without a problem of any kind.
I did replace them on the 16th oil and filter change just because I had a large collection of them building up from the previous changes. (O-rings come in each filter kit)
A question was asked about the early oil and filter changes Royal Enfield requires:
As the moving parts wear in during the break in period, a lot of fine metallic particles are deposited in the oil.
The large particles end up trapped in the oil filter but it is a good idea to get even the very fine particles out of the engine.
This explains the early oil and filter change requirements.
Cleaning the oil pump inlet screen (filter) is also a good idea during the initial oil change.
Often, debris that was lurking in the nooks and crannies of the engine become washed out during the break in period and these end up on the outside of the inlet screen.
I know that the Royal Enfield UCE's that were built during its early years of production often had large masses of cloth-like fiber found covering the pump inlet screen during the first oil change.
It was joked that someone had literally "thrown in the towel" while he was working.
Later it was found that some of the mechanics were wearing cotton gloves and it was fibers from these that were found in the pump inlet screen.
Royal Enfield changed its policy so these gloves are no longer used and the pump inlet clogging problem no longer exists on the newly built motorcycles.
Anyway, after the first early oil changes have been done the oil and filter change interval can safely go to the 10,000 km distance the book mentions.
