I gotta agree with the previous posts, 3.5k isn't a lot if you are already thinking of upgrading....
My first blast on a bigger bike was in October last year (Bandit 1200) and I knew when I rode the thing that I was nowhere near ready for a bigger bike, and I'd done probably 15,000 k's by that point.
Only a week or so ago when I rode the same Bandit again did I realize I'm now ready to upgrade. I've talked to riders who have said they actually wished they'd spent more time on their 250s before getting bigger bikes.
I really wouldn't be too hasty from jumping off the 250 onto something bigger, even once you do get your full. Your life is at stake. Enjoy the 250 while you have it, and use it to learn as much as you can about bikes and how to ride them. That experience will prove invaluable once you do upgrade.
What you have in your heart will be revealed through what you have in your life.
If things are going badly in our circumstances, the answer to what is happening to us outwardly is more often than not found in the mirror.
