How many don't have stators?

I have a designated track bike (09 ZX6R), had my first track day of the year yesterday. While prepping for it Saturday, i realized the rectifier/stator was not charging my battery.That night i pulled the batteries out of both my street and track bike, charged them fully. Plus had a 3rd laying around so I was able to bring 3 full batteries to the track. First 1 lasted 3 sessions (having to push start on 3rd). Next 2 lasted 2. I'm thinking I could have got down to 2 batteries lasting all day if I brought my tender for in between sessions.So how may of you removed the stators on your designated track bikes? From what I've read, the are about 5% of your bikes weight. And changing batteries like I did was not a big hassle. via /r/Trackdays https://www.reddit.com/r/Trackdays/comments/8ecety/how_many_dont_have_stators/?utm_source=ifttt
