Yes, sir, and you've come to the correct place to do that work!
Welcome to EM. Is your name pronounced similar to "pierce"?
Your Honda CB250 is definitely a good jumping off point for working on good mileage, but as with most bikes, you're going to need to work out some aerodynamics enhancements to really get good numbers. Gearing could be a starting point for you, though.
