I would back it off the limiter and I would daresay you'll pick up a little time rather than keeping it on the limiter. Was the seat moved when the kart was scaled? Honestly, I know it might make your kart a little heavier, but if you had to add some weight to get it balanced better you could always play with gearing to get some speed back. Is 81 on the front left and 79 on front right what you got on the scales? If I'm right, it looks like you're roughly 40% front and 60% rear. It's pretty close to a 50/50 split from side to side which is good. If I remember right, we always shot for 45/55 front/rear weight balance or something close to that.
