I second the other ideas in this thread.
If you have the sissy bar setup, take it off and switch to the non-sissy rails.
Dyna muffler and a
earthx battery can shave off some decent weight.
Removing stock air filter (convert to cone) and remove the battery box/toolbox(relocate new lithium to muffler bracket) will shave some weight, open up the middle of the bike and will move the battery weight lower.
Changing the shocks to some diy struts can also shave off some serious weight but will change the handling and ride.
I wish there was a place that I could ride up to and get my bike weighed.
