I have a 1979 R65 and am still running points. They seem to be fine and I have no great issue with them.
All is well at 110,000 miles.
I would not worry about changing unless you have some definate issue to resolve. But thats me....Lazy.
If you have some spare cash, I could find a use for it

If you do have a specific issue to resolve, like a sticking advance mechanism, then there are several kits on the market.
Watch out, prices vary wildly, so do your homework.
Boyer are one of the local suppliers - Can be sourced from Motobins, I believe.
