You say "up here" as in Canada"?I fill with bike on sidestand. Up here they won't turn on the pump until everyone is off the bike. That means rider and passenger as well. I asked about it and was told it was a safety issue if ever there was a gasoline fire .
I have NEVER filled up the bike without being on it and the bike upright.
And who ever said above they didn't want to climb on the bike with the gas hose in hand, I never do that either:
1/ Ride up next to the gas pump and turn bike off
2/ Take key and remove gas cap
3/ Fill tank
4/ Return hose to gas pump
It's just a habit, more gas is more better.....
