What gearing are you running? That is just a wheelie machine. IMO wheelies are cool for about 2 seconds and then they get real old, what fun is power when you can't turn cause your front wheels are in the air or you when you can't do anything cause you flipped over backwards!
Stock gearing 17/68, i play with trottle for break in the aluminium clucth pad and i turn slowly for not scratch the body the second run, he is too beautiful hihihi but the 3908 with big tire are more stable and roll over less than the 3905
