750 Brawler vs 650 AVS 2 at the track, right OOTB !

What I cant figure out is how you can alternate the wheel differential for the burnouts. Another good video by the way.
I have separate brake lines.. Kidding! The passenger tire will want to break loose first, so it heats up first. once it's sticky, then on the next try, the drivers side breaks loose because it's still wet, and it heats up.
