Joe,
I hope to see you in Loring in July. It's just too close to you to miss it! I plan to be there early to help with tech inspection. Regarding making changes, you might want to try it with the stock set up to see if you have any problems at 186 mph. If you do lower the front without lowering the back, it will reduce the trail which could make your bike more prone to a tank slapper.
In my opinion, sport bikes are designed to turn easily and quickly, not especially to run flat out in a straight line. I would advise to take the headstock bearings apart, clean, and re-grease, but don't overtighten them on replacement. Any resistance to steering inputs can set up a weave. The steering damper is still required because it is designed to restrict larger motions which happen in a wobble or tank slapper.
Check the LTA rules and make sure you're bike meets them, including tires less than 10 yrs. old, a metal battery hold down, and safety wire to prevent your oil filter from unscrewing (ask me how I know that one!)
