I didn't realize it was dual plugged and had two cams, one for each cylinder.
With the low compression I'm surprised it needs 91 to 93 AKI.
The R1200 takes 89 AKI and the R1250 takes 90 AKI.

Quote:As is usual in large-bore engines with a substantial compression ratio (R 1800’s is 9.6:1), mandated fuel is 95–98 RON (Research Octane Number).
