I replaced the bleed screws in my forks with bleeders(can't recall the name brand) so I can bleed the air off every so often while I ride. They worked great when I first got them, but now they blow a small amount of fork oil out the little hole when I bleed the air. So I disassembled them and attempted a cleaning. After I cleaned 'em up real good with WD-40. Hopefully they will bleed off just air now, no oil. Wasn't enough oil to change the height, just enough to make the top of my forks and triple clamp a little greasy.
