I've pulled them at 70 in second and had to come down , it just wanted to acellerate. I know the pros use the rear brake to keep the bikes up at Slow speeds . But if you are going to doit for long rides You need to get a windage tray (?) so you don't starve the motor on oil.
i was under the impression the windage tray was to keep the crank from frothing the oil.
i'm not much of a wheelie guy. fine to pull one at 45-50 til the end of first, just for fun, but extended wheelies are not my thing. acceleration, now that's my thing, and that's why i bought the busa. well, that and my wife liked the second seat. says it's comfy
