The stock JH 907 has next to no compression (8.5:1) and still fast combustion chambers, so octane rating is not likely to be an issue. I run a higher compression 907 (9.4:1) from a Lotus Eclat and see no issues on regular 95RON. My VW flat-4 in the family barge has 10.5:1 compression, slower chambers and still runs with no issues on 95RON... But beware of alcohol content, since it eats gaskets and fuel lines if they are not compatible, and fuel lines from the 70's are most likely not! -- Joachim
