omg. dont listen. go read www.stuntlife.com
i guarantee theres a sticky on how to wheelie.
the bouncing is to compress your fork springs, b/c when they unload its supposed to help bounce the bike up.
i guess i've never done wheelies on a 600, but 8k seems pretty high.
i have a 929 and can do power wheelies in first at 4k..just going at about 25 steady throttle, then get off the gas, then back on the gas..as he said power wheelies come up quick.
clutching it is the way to go. go for 2nd. dont clutch first till you learn second. i do em around 4k on my 929 you might have to go a little bit higher. Its like doing a power wheelie except when you get off the gas, hit the clutch, gas it, then let the clutch out.
for an in depth description check out stuntlife, cuz i dont really want to type that much.
btw. are you doing sit down or stand up?
