Take off your sub frame and get a punch you need to loosen the lock collar's. keep the rear wheel off the ground. When you do this do 16 or so turn's of top collar and then bring the second one up. Then make the two tight. Turn the bottom one into the top. Then turn the spring and let the bike down the rear will sit lower. Keep doing this and then you need to move the fork's up. get the front wheel off the ground then loosen the pinch bolt's and slide the fork's up to compensate for the rear. Then tighten the pinch bolt's.
Good luck,

A word on the advice given above...
Yes, you can lower the bike by reducing pre-load, but not 2-3 inches. Most manufacturers have a
maximum and a
minimum installed spring length specification. See what yours is.
Do go ahead and reduce the pre-load on the srpring to the maximum allowed distance specified by the manufacturer and see what it buys you. However, don't use a punch as crguy said to use... go ahead and spend the few $$$ for a spanner wrench and avoid damage to the shock and/or neighboring components.
If that doesn't work, you can have a local shop shorten the rear subframe a bit to effectively lower the seat without dramatic impact on bike/suspension setup.
