Was going to say he needs to bump from Intermediate, after seeing the video on YouTube never mind. He's one fast rider, to be moving like that in advanced. He's rock-in it.
Made that video after doing a race in Miami the first week of December. On the way north I took five days and rode a different MX track each day. What a great few weeks. I had so many race take offs to get rid of and actually put one new tire on the rear each session for two days. getting ready to go for a run so I can hang w/ some sportbike tracktime folks in 2018
