:welcome:
many of us have lowered the front end and had no clearance problems at all. i lowered mine 1.5 inches with no loss in movement or functionality. i'll be lowering another .25 inches soon and will still not have any issues. others have lowered even further and i don't believe there were any issues even then. keep in mind though that if you do lower the front end it is best to lower the rear with a lowering link or new spring setup to match how much the front is lowered to keep the dynamics of the bike as even as possible. it'll also help to relieve wrist strain and thus provide for a more comfortable ride.
anyways, i'm rambling. hope the lowering goes well and post some info and pics if you can. the members here love to see the progress we all make on our bikes, even with a mod that's been done a thousand times before
