When I say back off adn on again I mean, roll off the throttle quick enought to compress the forks and then roll back on the throttle quick enough that the preload along with your tug get the front wheel up. Once the front wheel is up then you can practive getting it higher and higher until you can ride it out adn eventually shift (no clutch) to 2nd and 3rd.
As far as throttle position after rolling up to 8G then roll off the throttle to get the front end to dip, then roll the throttle back on (pretty quick but use caution adn take it in steps as to not loop it) to about half throttle or so. Make sure you have you foot on the brake ready to check the bike in case it comes up too fast which generally isn't a problem if your going fast enough.
Whatever you do when getting back on the throttle, do it in steps and to diffrent throttle degrees. You'll start to get a feel what I'm talking about but by all means DO NOT GUN THE SHIT OUT OF IT!!
Ther biggest thing to get it off the ground is after you spin up to 8G, back off quick and then right back on when the forks compress while giving a tug on the bars.....
Sorry if my explaination is bad, I'm trying...
