With the bike on the ground, the forks are putting the top triple in tension. If you use a triple tree stand, the same thing is happening, but in the opposite direction.
Think of the whole fork & wheel assembly as pivoting at the lower triple clamp. When there is weight on the wheel, the top of the forks are pushing the top triple clamp towards the back of the bike. The opposite happens with the weight off the front end (even with a stand that uses the triple clamps and not the bottom of the fork legs).
Take the bike, put it on the rear stand.
Assuming that everything is already tight on the front end: loosen your top triple clamp bolts around the forks and the steering stem nut.
Then take a small jack and put it under the oil pan as far forward as you can get. (bottle jack from a small truck or scissor jack from a car works too) A small piece of wood between the jack and the oil pan helps steady everything and keeps you from marring the oil pan.
There will be a "sweet spot" where the top triple will just slide off by hand. Jack the bike up until you find this sweet spot. If you get to where the front tire is off the ground, you've gone too far because now all the weight of the front end is pushing the top triple forward.
Be careful jacking the bike up, as it will want to pivot side-to-side on the jack, and will be easily knocked over. You can steady it a little bit if you have a stand to put under the fork legs. Just remember to watch the fork legs. If they come off the stand, you've gone too far (just like when the front tire comes off the ground if you have no stand up front).
