Westy - Absolutely. the Key I think is not to be too abrupt with the throttle (not that I'm an electronics expert or riding god by any means), which I think causes the electronics to jump in and cut power very quickly. Are you clutching up or just bringing it up on the power? In second gear just sit back a bit from your usual riding position and roll it on. As the power comes in as revs rise just give a pull on the bars and up it comes. It'll do this in sport and race, and definitely comes right up. It wont stay up for ever because the electronics do bring it down eventually (not sure if its five seconds or what), but more than satisfying fairly vertical wheelies (depending on mode). In fact, I would go so far as to say that the anti wheelie has saved my ass on one particular cack handed experimentation, i was literally that vertical. If you just crack the throttle in first for sure the electronics will cut in quick and hold in down, but try my suggestion above and you can have some beautiful second gear overtakes on the rear (on the track of course).
Wish the roads weren't covered in salt to I could go try this just now! Of course I would only try this on the private roads around where I live
