Good luck.
I've done three Trackdays on my Connie, the only three I've ever done in my life...so don't consider me an expert.
Things I've learnt which you should consider.
-Suspension, if you haven't already dialed it in, use the Track day to experiment and dial it in once you have sag set. While it may not match what you want on the road, I learned a lot about how the bike behaves with a few tweaks.
-tire pressures, I run 42 on the road, but on the track experts have suggested dropping down into the low 30's. Last day out I think I ran 34 or 35. Research Dave Moss videos on the net and you can learn a lot.
- body position, this year I had private instruction on my track day and I learned a lot. The key thing I learned which help get the big connie around the track smoothly was leading with my head and body. As in my head/ body should be moving first, then countersteer, then bike. This enables you to ride ahead of the bike, versus trailing its movements.
Oh dragging pegs was a common experience in some corners. I've been able to improve on that with body position and ride the right line. But you may need more preload to lift the rear depending on your weight. On the track the bike Squats down a little more under power.
Otherwise enjoy, I know for sure I ride smoother and safe on the road for having done it.
