I got really good at doing them on sv650's (like I can pop it in 1st gear and walk it through 5th), the only problem with them is that eventually the crank bearings get starved for oil, and so far i've gone through 3 engines, and my new SV is doing really good so far... I try to not do wheelies, but they are just so fun to do.... but I havent ridden it at all since I got a ticket for reckless driving for popping a wheelie..
