[KA240SX808]

What's your setup?
I'm assuming that your in 2nd at the time of leaving the shack?
If you haven't already up your Rear Tire pressure to at least 55. That's normally what I run. Sometimes I step into 60psi but rarely do.
Sounds like a few clutch kicks could help keep that going.
You may need to come in a little more wide and shallow to keep it going though. But I know your not gonna keep that sweep coming from the shack in one shake especially from that low a speed in a KA.
So you can either come out the shack shallow and hold it as long as you can or come in a make like your gonna do a complete circle around the shack but switch to a right real quick and then kick it back out left.

Now idk the course nor have a driven on it. Just giving insight from what your video shows.
