I came across this video and was wondering what this technique is. It looks like half of a double blip. Maybe a zap, but the more I read about the zap VS double blip, the more confused I am as to what the difference is.
In this video, Mori-san pops the bike over a log by simultaneously revving the engine and letting go of the clutch. In some attempts there is a small bounce. He does the same thing over a rock. When going over the rock, the faster attempts look like a double blip to me.
If you have the patience for videos you don't understand, this channel has some interesting content. Like a demonstration of riding an XT250 Serow up a rock taller than the bike is.
