Can't seem to raise front forks! - They only go lower!

I bought a 2013 BMW S1000RR that was lowered and I'm in the process of attempting to raise the front forks. They're pretty low. I've loosened everything up, but I can't seem to lift enough to raise the front end and push the forks back down through the triple.

I need some advice or I'm never going to get to ride this thing....

I just watched a video and the kid was hitting the top of the fork with a rubber mallet to force it back down through the triple. Someone else was helping to pull upwards on the handlebars and/or triple at the same time. Is this an approved way of doing it or would that damage the tops of the forks and the adjusters?

Are you using a triple tree lift?

No, I only have the bike on a Pitbull rear stand on spools. I thought you couldn't use a triple tree lift because the brake line splitter is mounted in the center of the bottom of the triple?

There is one screw holding the T in place. Undo it and use a triple tree lift. Lightly tap the fork caps with a rubber mallet. They will come down.

Are you able to use some ratchet straps and lift from the upper triple tree?

fork alignment

Put the bike on the rear stand and a floor jack under the header to unload the front end (removed the front wheel) with the T clamp pinch bolts loosened you should be able to tun the upper tubes in the triples. If you cannot then spray a little lube in there and try. If you are still unable you may have a triple that is twisted and binding the forks. You should not ever need to resort to using a hammer to move your forks. Also when you get one tube where you want it bring the other in alignment using the axle as your guide. When it is correct it should thread into the other fork leg smooth and easy with two fingers. The forks may even appear to be uneven sticking out of the top clamp, that's ok as long as the axle is perfectly horizontal and suspension is NOT in a bind.

Never lift a bike by the headers. This is bush league stuff.

Thanks everyone for your comments and suggestions on this. I was able to finally push the forks back down through the triples. What I did was:

-- Raised the bike with the rear stand
-- Put a jack with a small block of wood under the center jack point
-- Jacked the bike up just enough to take the compression off the front wheel. Don't jack it up too much or the bike may want to become unstable and come out of the rear stand.
-- I put the appropriate socket on top of the front tube. I can't remember the size, but it's pretty large.
-- I used a 4 lbs dead blow mallet that I picked up at Harbor Freight ($11.99) to strike the top of the socket. This prevents any damage to the top of the fork tube.

After following this method, the fork tube moved down where I need it to be. Don't forget to use a torque wrench when tightening the bolts back on the tube. I believe the bolts on the tubes are only supposed to be tightened to 19nm (14 ft\lbs) or you risk crushing the tube.
