Welcome - hope you enjoy your new bike - I'm sure you will. Not sure if there are any Must do mods - but I haven't seen a stock Connie
except on the floor at a dealership.
I don't know why people keep calling a Throttlemeister a cruise control - IT'S A THROTTLE LOCK - nothing more.
If you want a real cruise control get a McCruise - not cheap but the good stuff never is. Mine works better then my 4 wheel vehicles.
Handlebar risers are a popular addition.
A top case is another - after a Phil's plate to mount it on.
Exhaust, seat and windscreen are often changed soon after getting a new bike for some people.
You state your parents live in FL - Where do you live and where are you getting the new bike from?
