Ok first off the system voltage is your voltage regulator is going over volts.
If it continues you will burn out your head lights.
You have a couple options. Depending on purchase date if it's under 2 years it will be covered under warranty.(warning this can be hard for the dealer to verfify take a video if u have a smart phone)
Option 2
Buy an upgrade voltage regulator I did a how to for the shindo f00012aa.
Buy a stock replacement I have a used one about 4000 miles on it if your intrested.
Heat yes there's lots of it I herd the grip pads form amercan sport bike help.
I know there a couple with header wrap and I'll probaly do mine when I put my new body work on.
