The 103 stage 4 kit i built 15k miles ago on a 09 flhx. Got the RB LSR 2-1 pipe on and put it in the dyno, made a few runs and started making all kind of racket in the rear rocker and cam ares. Pulled it apart and the rear intake lifter/ roller went south and took out the cams, pump and plate. Bike had a total of 27k miles when the stock B lifters went south. Replaced with S&S lifters with the travel limiters in them and S&S 585 chain drive cams. IF you run stock lifters in a high lift/agressive ramp cams, dont expect to get any mor than 30-40k miles out of em. Been wondering about mine, has almost 40k on my stock lifters and se260 cams. Rebuilding soon, so i hope she'll last.
