You are making too big of a deal out of it. Falling into the trap many humans have - fascination with numbers. It's just a number in your head, and is really meaningless. How about you strive for 200 km/hour? Oh, you probably crossed that one already, so you deserve some sort of reward. Some people hit 200 on a regular basis, and don't make a big deal - maybe just a smile.
BTW, I think 1 mile is not enough, especially for a stock bike. In that quest for those extra few mph, you may not have enough room to slow down. You also may not have that moment to look at the speedo, or a GPS - unless the GPS records max speed. I would just go and have some fun, regardless of what speed you will hit. That's all that matters. I would also put some cones at the end, so you have a reference point of where to start braking. This way you can gradually change your braking points in reference to the cone. Remember the kinetic energy you will be carrying is proportional to the square of the speed. This means that close to 200, the bike will be slowing down a lot lazier than you would expect.
So, go out and have some fun, let your wives/girlfriends watch at the place where you will have max speed right before the braking point. After you had enough passes, have a picnic, and enjoy talking about your experience.
