Are there folks using (semi-) synthetic oil? Is there a reason not to do this?

I don't but I see no reason not to.

I have always used good quality 20/50 in mine - that is what they were designed for.

I am sure there are arguments for and against but I stick with 20/50, and I don't feel like arguing

Oil threads are always contentious.

You can use semi synth but it's a waste of money really.
You also don't need a motorcycle oil as the clutch is lubed separately.
I just use a decent 20/50

I use a very special oil that can take me days to find. Traveling from supermarket to auto shops its hard sometimes to find the cheapest possible oil in town. Usually a straight 40 which is what I use in every engine I got.

The factory specify 20/50 - which is what we should put in - why argue with the people who built the bike?

Because they aren't very good at engineering?

Don’t forget; when pulling up chairs, no closer than a Covid compliant two metres apart....

Its easy to criticise the Indian factory but lets not forget that it was an Englishman who designed this engine and who with what ever parameters specified decided on 20/50 oil. I assume we all know better than him.
