There is a relay to the pump under the seat. when the ignition is turned on it runs for a few seconds and primes the bowls. After that, I believe it is triggered by ignition demand. It does not run continuiosly. There is at least one thread that goes into the diagnostics of the fuel pump. Check both the How-to as well as the specific F3 sections for fuel pump/priming threads.
Hope this helps, Ern

+1, high octane just drains the wallet faster.

I thought these bikes had a high compression ratio like 10:1 or 11:1 or so i was told or read somewhere, i don't recall where i got the info but whom i bought it from said it needed premium 91+ petrol .
Have i been played?
EDIT: I found this website with the info saying it's 12:1 compression which i would say requires 91+ octance unless you like pinging.

If you read the F3 owners manual, you'll see that Honda recommends 86 or higher.
Now here's where the even bigger confusion comes in.
In the USA, we use the AKI rating system for octane. Most other places use RON. Some manuals (and fuel stickers) will show the recommend RON rating of 91 octane or higher. 91 RON = 86 AKI (US regular pump gas).
Running anything higher than regular 87 in the USA should not be necessary in an F3.

It's a common misconception that higher compression is what decides the recommended octane rating. However, it's just part of the equation. Plug temp, ignition timing, etc play a larger role.
