I'm inclined to think there are 2 arguments here.
1) Is a higher octane petrol going to offer discernible benefits in engine performance and / or fuel economy to a carbureted Fazer 1000?
2) Are the additives in a premium petrol such as Shell V-Power going to offer discernible benefits in engine performance and / or fuel economy to a carbureted Fazer 1000?
My personal opinion is;
1) No - The engine was not designed to nor has the ability to make use of higher octane fuel.
2) Quite possibly - If the additives clean up deposits that have built up in the jets and other areas of the fuel system that have formed over time.
I'd argue that folks who report an improvement in performance / fuel economy from using V-Power are more likely to be seeing this through the effect of the additives than the higher octane rating.
