Pooping a wheelie? I've eaten some pretty odd and/or spicy things, but never had that happen!

Now, to pop a wheelie, it does come down to traction with the Jato. Hot days = more wheelies (greater traction). Like hyperman said, more weight toward the rear can help, as can stickier tires. I would skip the bleach idea, as that can simply deteriorate the rubber.

A wider tire and a medium compound can help you achieve more wheelies. The tires that I have are extremely soft (Imex skulls). They simply peel out 99% of the time.
