The replay is clean. I compared it to KLR's (fastest NTSC I could find) and it's all in the first lefthander. He starts braking way later but slows down more (down to 114 kmh !!!) and from there he can accelerate harder - better exit speed - faster thru the next turn (131 compared to your 126)
I made exactly the same mistake, my T1 time was 24.3xx too.
