Dont worry too much about it.
Just get on and go, sounds like your bikes in good order.
Ive done +300mi on a day trail ride on/offroad.
Think of it this way, its a tank and a half of gas or 3 tanks round trip.
Think about how many times you've filled it up since you've had it.
Think about the guys who ride beater 250s all over the world.
Why should you have any worries riding along interstates in the center of
civilization on a perfectly good motorcycle.
Have a great trip and remember, it is an adventure after all.
