Last October i traded my 05 RK with a little over 85,000 miles on a 2010 Ultra Classic. At around 80,000 miles i had the Cam Tenn. changed to Hydraulic and i had SE211 cams think thats the right # put in. Other than putting on Rhinehart True Duals at around 50,000 miles it was pretty much stock the whole time i had it and yes, i do miss it, especially after i had the cams and the cam Tenn. put in
