Take the left path. There are still boosts there, though you might have to do a drift boost or two to get through it. --- 3DS FC: 3050-7685-5267 PM me if you wanna play a match with me in Mario Tennis Open.
As you approach the ramp that shoots yo through the snakes mouth, position your racer so he's dead center. Be sure not to to any rolls as there's a chance you'll slim into the teeth, do a flip instead.
Since doing this I've never had issue with that route, that said however I no longer use that fork as even with persistent boosting you still end up short, the other fork is superior. --- I don't like killing people from geographical location A, but have no qualm killing people from geographical location B.
I just let go of the accelerator as I pass the last boost up into the mouth. If I have enough space, I do plenty of tricks, so that when I land, I can regain enough speed to get back in the race. --- http://backloggery.com/SetnaroX "Proper sound shatters glass. Proper sound shatters the Universe."
