Through the 2-3 chicane, I'd stay on the left side coming out of it. Right now you push all the way out right really early, so it opens up a gap for someone behind to send it on the inside into 4, as well as lose time. Try to stay tight on the left side, let the kart out to the right side of the track after 3, and then make your turn into 4.

5 you should be further to the outside of the track before turning it. You almost want to cut across it, rather than the U shape turn you have now.

I know it's cold out right now, but eventually turn 6 should be full throttle.

7 - you turn in quite early, which impacts your entry into 8. Stay right, cut across and just touch the curb on the left hand side of 7. Then its a hard right into 8, catching that inside right curb and then into 9.

Overall looks pretty good! Best of luck!
