I honestly do not know how Yamaha designed it. Checking it on the center stand. Remove dipstick, wipe it off and insert till threads touch and remove. When I change oil I only put in 2300cc of oil.Does that mean, it would read Full if the bike was on original centre stand? To be clear, that would mean that when they designed the dip stick, Yamaha assumed bike is on level floor and allowed for the engine being slightly tilted forward when on the stand?
Jim had a very good idea.
To be honest David, none of this matters... threaded in... resting on threads... on the centerstand, front wheel chocked.... tongue situated just so... none of that matters. Fill it with 2.5l, configure it however works best for you whilst on the road and check the level. Mark the dipstick at that level (file or whatever) and call it a day. That's your full mark. If you want to get real fancy, fill it with 1.5l and put a mark for 1l low... add the extra liter and now you have a full and 1l low mark. Just make sure you set your configuration so it's easily repeatable on the road.... threads and chocks be damned.
