Agreed, you dont want to be pulling the cluthc in, letting your revs go up, and then dump the clutch. What you want to do is give gas, slip the clutch(one or two fingers, pull in just enough to take power from the wheel, and immidiatily release(let it slip right out of your finger, dont actually let it out), as you let it go give it a little more gas. Chances are what you are doing is pulling it in, givivng it a bunch of throttle, letting it out to slow, and letting of throttle. This is bad for the clutch and bad for wheelies. The idea is to have the bike pulling, and then cut power just long enough to give a wieght transfer, annd then allow abrupt power to the wheel to bring up, with power constant or increasing after clutch is released, then let of power as you approach bp, or as close as your skill allows. cover your brake. Good luck and ask more questions as you go.
