Been Around the Block
Sounds like quite a successful session. I think you have enough hp to crack 100mph. Team Afflick over here holds quite a few records in smaller classes, mainly 100cc. Here's what he once wrote "To go 100mph without a fairing you will need 23-25 rear wheel HP. We ran 94.5mph with 21hp and then 106mph with 28hp unfaired." Keep in mind this was with a bike that was physically smaller than yours. But if you drop the nose down and keep it as clean as possible drag-wise I think you'll do it.
