Miles per Tank?

[freak400]

I am curently building a 250r. Motor will be stock (except a pipe), how many miles should I expect on a tank of gas just running normal?? Stock tank by the way.

When I ran GNCC, I could go the entire race on one tank (IMS 3.6 gallon) and still have some left. No need to ever stop and refuel.
