lol i think most of these guys "wheelies" are these i meter long "pop" the tires up and slam them back down sort of things. lots of good advise here for that. "popping wheelies"
i consider the word "wheelie" as raising the front tires and holding them up as long as possible. almost anything could "pop a wheelie" hell ollieing a blaster would be more impressive.
why i say this is even a stock blaster can "pop a wheelie" no problem. he asked how to get better wheelies out of the bike.
shorter gears?? wont help, yes it will want the front to come up easier (aswell as tire spin) but at the same time as soon as its up the gears are too short and the bike revs out hurting your pride and bike. Longer gears is what you want, i know what most are thinking longer gears will kill power and torque and make it harder. This isnt true, i did a small jump to a 14 tooth sprocket on my blaster when it was stock and it would pull every gear it would with the 13 it just extends the tourque/power curve longer so that when you pop the bike up and get it in balance point you have more rpm to help ride it out.
theres many other ways to help setup a bike for better catwalks. ive seen many youtube videos of blastys wheeling and i havnt been much impressed. most of the good ones are using rear brakes to help which takes skill (this is good). i havent quite seen anyone do them like i doo. 70-80kph stand up haul on the bars get the bike up in balance point and hold throttle at that point. If dont perfectly you can go forever and not have to stop, the highspeed is bittersweet it helps smooth out the transition abit aswell as makes it much more dangerious
