Have a Y2K Ultra with 13,000 mi and I had to replace the shift levers and shaft due to excessive wear. The teeth were worn down to nothing in some areas. I maintain the bike and am pretty light on the shift pressure when shifting. Anyone else had to replace these parts with so little miles and is it a comman thing with HD? Any recommendations on aftermarket parts that might last a little longer. This is my first Harley. Thanks...
