I was watching this YouTube earlier today, I think it's around the 2015, 2016 years of R1 crank had been experiencing failures, this guy has done some pretty extensive investigations as to why and it seems to be supported by changes Yamaha made in subsequent years, which suggests Yamaha knows it is a fault.
Have a look and make up your own mind, just posting in case you're running these in your mini.

I think nearly all R1 powered Minis are RN09 (5PW Engine) and older.

This seems to be the 2CR Engine (RN32 model R1).

 

Interesting Video though!
