When I took my Boyer equipped r80 to South America in 1980, I did take a set of points along with me. I ails the bike in Bolivia, took the Boyer to Australia, put it on a R90/6 and then rode around Australia. Boyer seemed to work better crossing rivers at running when underwater.
Not bad temperatures from -5c to +45C.
There a number of failures that I could envisage with points that would also require having replacement parts to hand to get you out of a fix..
