I've done this "test" on both my other bikes, and the front wheel never actually came off the ground. I'm wondering if this is due to a unique weight distribution in the 929, if its a by-product of the racetech mod, or, if when I put the forks back on the bike, I torqued something incorrectly (I don't have a torque wrench) and the forks are binding somehow.
Depending on just how hard you are "pulling it up hard", that doesn't sound right to me at all. It could possibly be caused by rotational misalignment on the upper and lower triples, incorrect procedure used for tightening the front axle or anything else in the "chain of events" required when reassembling the front end.
I suspect you may have the bottoms of the tubes pinched (or spread) by not following a standard procedure for tightening the axle clamping bolts.
You need to keep the bike on the front stand during the entire procedure. To eliminate any binding from the stand, I recommend a full front stand or hang the bike from the rafters (since you had the forks off the bike, I'm assuming you have a means to hold the bike up without using the forks).
Since I no longer have a 929, I forget which side you tighten first, but you put all the pieces together without tightening the pinch bolts or axle bolt. Tighten the pinch bolts on the side the axle bolt goes in, finger tighten the axle bolt then with the front end still off the ground, spin the front wheel and hit the front brakes. Do this a couple of times and then tighten the pinch bolts on the other side. Now torque down the axle bolt.
This aligns the wheel and fork legs to the axle center and prevents the axle from being overtightened and the forks from being out of line.
