"Wheelies will ruin your stem bearings fast.Sometimes a forkspring will break unless you learn to set it down gently. This is a quality product.AVOID your dealer if not under warranty. Disassemble front end.Knock out old races.I use a long nut & bolt with fat washers to slide the new races in(grease them alittle to ease future removal).Be sure to generously pack the bearings with quality grease from the inside untill it comes out between rollers,too much grease is impossible....reassemble,and resume wheelies. To check your bearings,the front must be elevated...turn wheel left and right.If it favors being straight,it means the bearing is starting to wear,and you should consider replacing before it starts to make a clunking noise.There should be zero play detected when puling on lower fork tubes."
