2 stroke is not where I would start. They have put me on my ass a couple of times. Now my YZF 450 used to pull 'em up in 3rd and it was a 4 speed tranny.
Trail riding I power wheelie and some clutch up's on the 2 stroke (300exc) but that's a lot different from getting to an maintaining balance point, which is the stuff wheelies are made of.

BTW Ultimate wheelie machines
