Just take it slow and steady - like 2 or 3 years of gentle practice.
I only use the "off/on the power" technique - with a the ZX10r it's easy. I first started with fast getaways from the light's making the front go light, then progressed onto giving it deliberately large handfuls of power over crests in first or second gear. After that, coasting at 7k and off/on - weeeee - up it comes !!!
You need to get to a stage where you're not shitting yourself everytime the front comes up - which took me about a year.
After that, it'll just develop.
I'm now at the stage where I need to master changing gears while up - which I think will come next year - I can almost change the gear now, but every time I do the front goes down, I don't know how the biek will react when I gas it on in second - I think I'll be back to the "shitting myself" stage.
I've not crashed yet - but clearly it's a dangerous pastime.
An added benefit (if you can call it that) is that you don't panic when the front comes up unexpectedly - like powering through the gears on Welsh A roads when it comes up at 130mph, where argueably it's not the best time to panic unduely - just calmly shift your weight forward and try to land it before you hit the mountain.
