If going to YouTube and search for "Mushroom Gorge no-glitch" there will be many world record runs that, right before the finish line, the players will jump over the canyon gap. They usually use Funky Kong and the Flame Runner bike.
I tried that but simply can't jump over though. Using a Mushroom boost, Funky Kong always fall a little and not able to catch the road, but hit the side of the mountain instead and fall off. I also tried Wheelie first, and then use the Mushroom boost, and the same thing happened.
Is there a way to do it? Such as Mushroom over some bump, and then also perform a trick for the jump, so that the jump is higher? -- How is that done?
